ITEM 1.		BUSINESS

     Organization. Marine Petroleum Trust (“Marine”) is a royalty trust that was created in 1956 under the laws of the State of Texas. Marine was organized for the sole purpose of providing an efficient, orderly, and practical means for the administration and liquidation of rights to payments from certain oil and natural gas leases in the Gulf of Mexico, pursuant to license agreements and amendments thereto between Marine’s predecessors and Gulf Oil Corporation (“Gulf”). As a result of various transactions that have occurred since 1956, the Gulf interests are now held by Chevron Corporation (“Chevron”), Elf Exploration, Inc. (“Elf”), and their assignees. Marine may not engage in any other trade or business.

     The indenture pursuant to which Marine was created (as amended, the “Indenture”) provides that the corporate trustee is to distribute all cash in Marine, less an amount reserved for the payment of accrued liabilities and estimated future expenses, to unitholders of record on the last business day of February, May, August and November. Payments are to be made on the 28^th day of September, December, March and June of each fiscal year. If the 28^th falls on a Saturday, Sunday or legal holiday, the distribution is payable on the immediately preceding business day.

     The Indenture also provides that the term of the royalty trust will expire on June 1, 2021, unless extended by the vote of the holders of a majority of the outstanding units of beneficial interest.

     Marine’s wholly-owned subsidiary, Marine Petroleum Corporation (“MPC”), holds title to interests in properties subject to Marine’s interests that are situated offshore of Louisiana. Ninety-eight percent of all oil, natural gas, and other mineral royalties collected by the subsidiary less the cost of receiving and collection are paid to Marine. MPC retains the remaining two percent of the overriding royalties along with other items of income and expense until such time as the board of directors declares a dividend out of retained earnings. MPC, like Marine, is prohibited from engaging in a trade or business and does only those things necessary for the administration and liquidation of its properties.

     Marine’s only industry segment or purpose is the administration and collection of royalties.

     Royalties. Marine’s rights are generally referred to as overriding royalty interests by the oil and natural gas industry, and we sometimes refer to them as overriding royalty interests in this annual report. All production and marketing functions are conducted by the working interest owners of the leases. Revenues from overriding royalties are paid to Marine either (i) on the basis of the selling price of oil, natural gas and other minerals produced, saved and sold, or (ii) at the value at the wellhead as determined by industry standards, when the selling price does not reflect the value at the wellhead.

     Marine holds an overriding royalty interest equal to three-fourths of 1% of the value at the well of any oil, natural gas, or other minerals produced and sold from the leases described in the “Properties” section below. Marine’s overriding royalty interest applies only to existing leases and does not apply to new leases that Chevron or Elf may acquire.

     Marine also owns a 32.6% equity interest in Tidelands Royalty Trust “B” (“Tidelands”), a separate Texas trust, which owns interests in the oil, natural gas, or other mineral leases acquired by Gulf and/or its transferees and assignees in a 1,370,000-acre area of the Gulf of Mexico (the “Royalty Area”). The term of the Tidelands royalty trust will expire in 2021, unless extended by the vote of the holders of a majority of the outstanding units of beneficial interest. Tidelands’ indenture provides that the corporate trustee is to distribute all cash in the trust, less an amount reserved for payment of accrued liabilities and estimated future expenses, to unitholders of record on the last business day of March, June, September and December of each year. Such payments are to be made within 15 days after the record date. Distributable income is paid from the unconsolidated account balances of Tidelands. Distributable income is comprised of (i) royalties from offshore Texas leases owned directly by Tidelands, plus (ii) 95% of the overriding royalties received by the subsidiary that are paid to Tidelands on a quarterly basis, less (iii) administrative expenses of Tidelands. We recommend that you read Tidelands’ public filings for a description of its risks, business, properties and financial condition and results of operations.

     As of the date of filing of this Annual Report on Form 10-K, the leases subject to Marine’s interests cover 238,084 gross acres (including Tidelands’ interest in 22,948 leased acres). These leases will remain in force until the expiration of their respective terms. Leases may be voluntarily released by the working interest owner after all oil and natural gas reserves are produced. Leases may also be abandoned by the working interest owner due to the failure to discover sufficient reserves to make development economically worthwhile. In addition, the federal government may force termination of a lease if the working interest owner fails to fully develop a lease once it is acquired. The Tidelands lease on West Cameron Block 262 covering 2,500 acres was terminated during the year.

     For the year ended June 30, 2007, approximately 57% of Marine’s royalty revenues were attributable to the sale of oil and approximately 43% were attributable to the sale of natural gas. The royalty revenues received by Marine are affected by a number of factors, including seasonal fluctuations in demand, ability of wells to produce due to depletion and by changes in the market price for oil and natural gas. The following table presents the percent of production from various companies which paid over 90% of the royalties in each of the past three years.

		Year Ended June 30,
Company		2007				2006				2005
Chevron USA, Inc.			63	%			65	%			78	%
Walter Oil & Gas Corporation			7	%			8	%			—
Anglo Suisse Offshore Partners LLP			6	%			6	%			—

Others			2	%			8	%			9	%
			100	%			100	%			100	%

In addition, Marine’s revenues from its equity interest in Tidelands accounted for approximately 19%, 9% and 14% of Marine’s revenue for the years ended June 30, 2007, 2006 and 2005, respectively. Tidelands has reported that royalty revenues from Baron Petroleum, Noex Energy Inc., W & T Offshore and Devon Energy Production Company accounted for more than 95% of Tidelands’ royalty revenue for the years ended December 31, 2006, 2005 and 2004.

     Marine derives no revenues from foreign sources and has no export sales.

     Trust Functions. Marine is administered by officers and employees of its Trustee, Bank of America, N.A. See “Management and Principal Unitholders.”

     All aspects of Marine’s operations are conducted by third parties. Oil and natural gas companies that lease tracts subject to Marine’s interests conduct the production and sale of oil and natural gas and the calculation of royalty payments to Marine. Marine’s distributions are processed and paid by Mellon Investor Services, LLC as the agent for the trustee of Marine.

     MPC leases office space in Dallas, Texas to provide work space and record storage for MPC and Tidelands’ wholly-owned subsidiary corporation, Tidelands Royalty Trust “B” Corporation. The cost of this office facility is shared by MPC and Tidelands Royalty Trust “B” Corporation proportionately based on each entity’s gross income.

     The ability of Marine to receive revenues is entirely dependent upon its entitlement to its rights with respect to the leases held by Chevron and its assignees in the Gulf of Mexico (as more fully described in “Properties” below). Moreover, no revenues are payable to Marine until sales of production commence from any such lease.

     The royalty interests held by Marine are depleting with each barrel of oil and mcf of natural gas produced. No funds are reinvested by Marine; thus, these depleting assets are not being replaced.

ITEM 1A.		RISK FACTORS

     The following is a summary of the principal risks associated with an investment in units of Marine.

     Marine’s quarterly distributions are highly dependent upon the prices realized from the sale of oil and natural gas. A significant downward movement in the prices for oil and natural gas could have a material adverse effect on our revenues and operating cash flows, which could decrease our distributions to unitholders. Historically, prices have been volatile and are likely to continue to be volatile in the future due to factors beyond our control. These factors include, but are not limited to:

	•		political conditions worldwide, in particular political disruption, war or other armed conflicts in oil producing regions;
	•		worldwide economic conditions;
	•		weather conditions;
	•		the supply and price of foreign oil and natural gas;
	•		the level of consumer demand;
	•		the price and availability of alternative fuels;
	•		the proximity to, and capacity of, transportation facilities; and
	•		the effect of worldwide energy conservation measures.

     Moreover, government regulations, such as regulation of natural gas transportation and price controls, can affect product prices in the long term.

     Lower prices may reduce the amount of oil and natural gas that is economic to produce and reduce net profits available to Marine. The volatility of energy prices reduces the predictability of future cash distributions to unitholders. Substantially all of the oil, natural gas and natural gas liquids produced from the Royalty Area is being sold under short-term or multi-month contracts at market clearing prices or on the spot market.

     The occurrence of drilling, production or transportation accidents and other natural disasters in the Royalty Area will reduce distributions. These occurrences include blowouts, cratering, explosions, environmental and hurricane damage that may result in personal injuries, property damage, damage to productive formations or equipment and environmental damages. For example there were two major hurricanes in the Gulf of Mexico during the fiscal year ended June 30, 2006. Some wells were lost due to these hurricanes. Other wells were off production for most of the quarter that ended December 31, 2005 and did not start recovering until the quarter that ended June 30, 2006. As a result, oil and natural gas production for the first, second, third and fourth quarters of fiscal 2006 were down 45%, 61%, 41% and 7%, respectively, from the oil and natural gas production realized in the fourth quarter of fiscal 2005.

     Oil and gas operations have been, and in the future will be, affected by federal, state and local laws and regulations and other political developments, such as price or gathering rate controls and environmental protection regulations. Although we are unable to predict changes to existing laws and regulations, such changes could significantly impact our royalty interests.

     The properties in the Royalty Area are owned by independent working interest owners. The working interest owners manage the underlying properties and handle receipt and payment of funds relating to the Royalty Area and payments to Marine for its royalty interests. The current working interest owners are under no obligation to continue operating the properties. The Trustee, Marine and its unitholders do not have the right to replace an operator.

     The working interest owners may at any time transfer all or part of the properties in the Royalty Area to another unrelated third party. Unitholders are not entitled to vote on any transfer, and Marine will not receive any proceeds of any such transfer. Following any transfer, the Royalty Area will continue to be subject to Marine’s royalty interest, but the net proceeds from the transferred property would be calculated separately and paid by the transferee. The transferee would be responsible for all of the obligations relating to calculating, reporting and paying to Marine its royalty interest on the transferred portion of the Royalty Area, and the current owner of the Royalty Area would have no continuing obligation to Marine for those properties.

     The current working interest owners or any transferee may abandon any well or property if it reasonably believes that the well or property can no longer produce in commercially economic quantities. This could result in termination of Marine’s royalty interest relating to the abandoned well.

     The Marine trust may be terminated and the Trustee may sell Marine’s royalty interests if holders of 80% of the units of beneficial interest of Marine approve the sale and vote to terminate the trust. Following any such termination and liquidation, the net proceeds of any sale will be distributed to the unitholders and unitholders will receive no further distributions from Marine. Any such sale may not be on terms acceptable to all unitholders.

     The net proceeds payable to Marine are derived from the sale of oil and natural gas, which are depleting assets. Accordingly, the portion of the distributions to unitholders attributable to depletion may be considered a return of capital. The reduction in proved reserve quantities is a common measure of depletion. Future maintenance and development projects in the Royalty Area will affect the quantity of proved reserves. The timing and size of these projects will depend on the market prices of oil and natural gas. If operators of the Royalty Area do not implement additional maintenance and development projects, the future rate of production decline of proved reserves may be higher than the rate currently experienced by Marine.

     Voting rights as a unitholder are more limited than those of stockholders of most public corporations. For example, there is no requirement for annual meetings of unitholders or for an annual or other periodic re-election of the Trustee. Unlike corporations which are generally governed by boards of directors elected by their equity holders, Marine is administered by a corporate Trustee in accordance with the Indenture and other organizational documents. The Trustee has limited discretion in its administration of Marine.

     Terrorist attacks and the threat of terrorist attacks, whether domestic or foreign, as well as the military or other actions taken in response, cause instability in the global financial and energy markets. Terrorism and other geopolitical hostilities could adversely affect Marine’s distributions to its unitholders or the market price of its units in unpredictable ways, including through the disruption of fuel supplies and markets, increased volatility in oil and natural gas prices, or the possibility that the infrastructure on which the operators of the underlying properties rely could be a direct target or an indirect casualty of an act of terror.

     The leasehold working interests that are subject to the rights held by Marine are owned, in most cases, in whole or in part by Chevron, or other oil and natural gas exploration and production companies. Certain information as to reserves, availability of oil and natural gas, average production cost (lifting cost) per unit, undeveloped acreage, net wells and net acres, with respect to the particular leases subject to Marine’s interests, lies solely within the knowledge of these concerns. Engineering data, if any, regarding these leaseholds would have been compiled principally by or for the working interest owners of these leaseholds. Historically, Marine has not had access to this information and does not expect to have access to this information in the future.

     The Trustee does not intend to pay any amounts for the new Texas margin tax for tax year 2007, based on Marine’s belief that it is exempt from tax as a passive entity; however, there is currently no clear statutory authority that Marine meets requirements for the margin tax exemption as a passive entity. If it is subsequently determined that Marine is not exempt from the margin tax, Marine would be required to deduct and withhold from future distributions the amounts necessary to pay the margin tax for the entire 2007 year, including the tax liability accruing on income distributed after December 2006, attributable to 2007 revenues, from which no tax was withheld.

ITEM 1B.		UNRESOLVED STAFF COMMENTS

     None.

ITEM 2.		PROPERTIES

     General. Marine is not engaged in oil and natural gas operations, although its income is based upon the oil and natural gas operations of others. Marine’s income is derived from contracts that provide for payments in the nature of overriding royalties made to Marine based on oil and natural gas sales from certain leases in the Gulf of Mexico.

     Reserves. Marine is not engaged in the production of oil or natural gas. Marine’s income is derived from overriding royalty payments that are carved out of working interests in oil and natural gas leases in the Gulf of Mexico. Marine does not have the engineering data necessary to make an estimate of the proved oil and natural gas reserves attributable thereto (nor the present value of future net cash flows from such reserves), and is not entitled to receive such data from the owners of the working interests from which Marine’s interests are derived. Similarly, Tidelands does not have access to the engineering data necessary to make an estimate of the proved oil and natural gas reserves attributable thereto. See also “Difficulty in Obtaining Certain Data” below.

     Since Marine does not have access to this reserve information, Marine is unable to compute the standardized measure of discounted future net cash flows therefrom.

     Marine did not file any reports during the fiscal year ended June 30, 2007 with any federal authority or agency with respect to oil and natural gas reserves.

     Due to the nature of Marine’s business, it does not have any delivery commitments.

     Production. Information regarding the net quantities of oil and natural gas produced with respect to Marine’s overriding royalty interests (excluding its equity interest in Tidelands) for each of the last three fiscal years, as well as the average sales price per unit of oil and natural gas produced upon which payments to Marine are based, is set forth in the following table:

		Year Ended June 30,
		2007				2006				2005
Net Quantities Sold
Oil (in barrels (“bbls”))			42,260				35,336				49,132
Natural Gas (in thousands of cubic feet (“mcf”))			292,326				231,811				309,951
Average Price
Oil (per bbl)		$	65.98			$	54.53			$	46.02
Natural Gas (per mcf)		$	7.30			$	8.65			$	6.29

     Information about average production cost (lifting cost) per unit of production has been omitted due to its unavailability and inapplicability to Marine. For more recent information regarding prices, see “Management’s Discussion and Analysis of Financial Condition and Results of Operations” below.

     Productive Wells. Based on the latest public records reviewed by Marine, there were approximately 240 producing wells subject to Marine’s interests, some of which contained multiple completions. Approximately 100 wells were classified as oil wells and approximately 140 wells were classified as natural gas wells. Most of the wells produce both oil and natural gas. See “Difficulty in Obtaining Certain Data” below.

     Drilling Activity. The following table shows the number of wells drilled in which Marine has an interest (including its equity interest in Tidelands) for each of its last three fiscal years:

		Year Ended June 30,
		2007				2006				2005
Development
Oil			15				10				20
Natural Gas			30				15				27
Dry			3				2				8
Totals			48				27				55

     Information regarding net wells or acres is not included since Marine does not own any working interests.

     Lease Acreage. Marine has an overriding royalty interest (including its equity interest in Tidelands) in 64 different oil and natural gas leases covering 238,084 gross acres. These leases are located in the Central and Western areas of the Gulf of Mexico off the coasts of Louisiana and Texas. This acreage is presented in the following table:

Leases Granted by(1):		Producing
United States			232,554
State of Texas			640
State of Louisiana			4,890
			238,084

     Expired Leases. The 2,500-acre lease on West Cameron Block 262 expired at the end of its 5-year term. There were no wells drilled on the lease.

     The overriding royalty interest owned by Marine is a fractional interest out of total oil and natural gas sold, and is free and clear of all operating costs. The actual percentage interest in a lease attributable to Marine’s interest varies from lease to lease. The acreage weighted average percentage interest attributable to Marine’s interest in all of these leases is 0.5811%.

     Present Activities. As of June 30, 2007, public records indicate that nine wells are either being drilled, re-drilled or worked over on tracts in which Marine has an interest. Public records indicate that operators have designated locations for four additional operations. There is no assurance that these wells will be drilled, and if they are drilled, that they will be successful.

     Difficulty in Obtaining Certain Data. Marine’s only activities are the collection and distribution of revenues from overriding royalties on certain oil and natural gas leases in the Gulf of Mexico, pursuant to purchase agreements between Marine’s predecessors and Gulf and its transferees. The leasehold working interests that are subject to the rights held by Marine are owned, in most cases, in whole or in part by Chevron, or other oil and natural gas exploration and production companies. Certain information as to reserves, availability of oil and natural gas, average production cost (lifting cost) per unit, undeveloped acreage, net wells and net acres, with respect to the particular leases subject to Marine’s interests, lies solely within the knowledge of these concerns. Engineering data, if any, regarding these leaseholds would have been compiled principally by or for the working interest owners of these leaseholds. In the past, Marine has asked for such information and was told it is not entitled to receive such information. Marine believes that it will not be provided access to such information in the future. As a result, Marine is not able to obtain all of the information required to be disclosed under Item 102 of Regulation S-K and Securities Exchange Act of 1934 Industry Guide 2.

ITEM 3.		LEGAL PROCEEDINGS

     Neither Marine nor MPC, nor any of their respective properties, is a party to or subject to any material pending litigation as of the date hereof.

ITEM 4.		SUBMISSION OF MATTERS TO A VOTE OF SECURITY HOLDERS

     No matters have been presented to the unitholders to be voted upon during the fiscal year ended June 30, 2007.

ITEM 5.		MARKET FOR REGISTRANT’S COMMON EQUITY, RELATED UNITHOLDER MATTERS AND ISSUER PURCHASES OF EQUITY SECURITIES

     The units of beneficial interest in Marine trade on the Nasdaq Capital Market under the symbol “MARPS.” Distributions of cash are made to unitholders quarterly. The following table presents the range of high and low sales prices by quarter for the past two years. The per unit amount of cash distributed to unitholders for each of these quarters is also presented in the table.

		Sales Price
										Distributions
Quarter Ending		High				Low				Per Unit
September 30, 2006			31.00				19.58				0.568
December 31, 2006			26.24				22.29				0.576
March 31, 2007			27.79				23.20				0.613
June 30, 2007			32.64				26.05				0.703
September 30, 2005			28.50				24.90				0.609
December 31, 2005			31.98				27.50				0.789
March 31, 2006			34.00				22.82				0.392
June 30, 2006			25.60				20.00				0.447

     Marine is authorized to issue and has issued 2,000,000 units of beneficial interest. On June 30, 2007, these outstanding units were held of record by 449 unitholders.

     Marine must distribute to its unitholders all cash accumulated each quarter, less an amount reserved for accrued liabilities and estimated future expenses. The amount reserved varies from quarter to quarter and amounted to $35,000 for the distribution paid on June 28, 2007. Such distributions have been made since Marines’ inception and will continue so long as the income from oil and natural gas royalties exceeds administrative costs.

     Distributions fluctuate from quarter to quarter due to changes in oil and natural gas prices and production quantities. Distributions are determined by the cash available to Marine on the determination date.

     Marine does not maintain any equity compensation plans. Marine did not repurchase any units of beneficial interest during the period covered by this report.

ITEM 7.		MANAGEMENT’S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND RESULTS OF OPERATIONS

     Critical Accounting Policies. As an overriding royalty owner, actual production results are not known to us until reported by the operator, which could be a period of 60-90 days later than the actual month of production. To comply with accounting principles generally accepted in the United States of America, we must estimate earned but unpaid royalty from this production. To estimate this amount, we utilize historical information based on the latest production reports from the individual leases and current average prices as reported for oil by Chevron USA and the spot market price for natural gas delivered at the Henry Hub in Louisiana for the period under report.

     Results of Operations. Marine’s revenues are derived from the oil and natural gas production activities of unrelated parties. Marine’s revenues and distributions fluctuate from period to period based upon factors beyond Marine’s control, including without limitation the number of leases subject to Marine’s interests, the number of productive wells drilled on leases subject to Marine’s interests, the level of production over time from such wells and the prices at which the oil and natural gas from such wells are sold. Marine believes that it will continue to have revenues sufficient to permit distributions to be made to unitholders for the foreseeable future, although no assurance can be made regarding the amounts thereof. The foregoing sentence is a forward-looking statement and is subject to numerous factors. Factors that might cause actual results to differ from expected results include reductions in prices or demand for oil and natural gas, which might then lead to decreased production; reductions in

production due to depletion of existing wells or disruptions in service, including as the result of storm damage, blowouts or other production accidents, and geological changes such as cratering of productive formations; and the expiration or release of leases subject to Marine’s interests.

     Marine’s income consists primarily of oil and natural gas royalties and is based on the value at the well of its percentage interest in oil and natural gas sold without reduction for any of the expenses of production. “Value at the well” for oil means the purchasers’ posted price at its receiving point onshore, less the cost of transportation from the offshore lease to the onshore receiving point.

     Summary Review. Marine’s net income for the year ended June 30, 2007 amounted to $5,950,819 or $2.98 per unit as compared to $4,175,357 or $2.09 per unit in fiscal 2006 and $4,739,610 or $2.37 per unit in fiscal 2005.

     These results also include income from Marine’s equity interest in Tidelands which amounted to $1,189,027 for fiscal 2007, $405,260 for fiscal 2006 and $710,818 for fiscal 2005. Income from Tidelands contributed approximately 19% of Marine’s royalty income for fiscal 2007 as compared to 9% and 14% of Marine’s income for fiscal 2006 and 2005, respectively.

     Marine’s administrative expenses increased to $218,089 in fiscal 2007 from $217,665 spent in fiscal 2006. This increase was substantially due to increased fees for professional services.

     Interest income increased to $78,418 in fiscal 2007 from $53,492 realized in fiscal 2006 due to a moderate increase in interest rates.

     The following table shows the number of wells drilled or worked over on leases in which Marine has an interest (including its equity interest in Tidelands) and the number of producing wells for the past three fiscal years.

		Year Ended June 30,
		2007				2006				2005
Drilled			48				27				55
Producing			240				260				320

     Hurricanes Katrina and Rita are the primary cause of the 25% decrease since 2005 in the number of producing wells on leases in which Marine has an interest. The majority of the loss of producing wells was due to Hurricane Katrina. In addition, some wells have been lost due to depletion.

     A significant amount of equipment and personnel that would normally be working on drilling new wells and working over old wells had to be used to restore wells and facilities damaged by the hurricanes.

     The following table and related discussion and analysis shows the royalty income, the net quantities sold, and the average price received for oil and natural gas during the past three years excluding Marine’s equity interest in Tidelands.

		Year Ended June 30,
		2007				2006				2005
Income from:
Oil royalties		$	2,788,226			$	1,937,145			$	2,260,902
Natural gas royalties		$	2,133,187			$	2,004,925			$	1,949,859
Totals		$	4,921,413			$	3,942,070			$	4,210,761
Net quantities sold:
Oil (bbls)			42,260				35,336				49,132
Natural gas (mcf)			292,326				231,811				309,951
Average price:
Oil		$	65.98			$	54.53			$	46.02
Natural gas		$	7.30			$	8.65			$	6.29

     Oil and Gas Royalties — 2007 and 2006. Revenue from oil royalties amounted to $2,788,226 in fiscal 2007, an increase of 44% from the $1,937,145 realized in fiscal 2006. The average price realized for a barrel of oil increased 21% to $65.98 over the $54.53 realized in fiscal 2006. Oil production increased 20% to 42,260 barrels.

     Revenue from natural gas royalties amounted to $2,133,187, an increase of 6% over the $2,004,925 realized in fiscal 2006. The average price of a thousand cubic feet (mcf) of natural gas decreased 16% to $7.30 and production increased 26% to 292,326 mcf.

     Oil and Gas Royalties — 2006 and 2005. Revenue from oil royalties amounted to $1,937,145 in fiscal 2006, a decrease of 16% from the $2,260,902 realized in fiscal 2005. The average price of a barrel of oil increased 18% to $54.53 and production decreased 28% to 35,336 barrels.

     Revenue from natural gas royalties amounted to $2,004,925, an increase of 3% over the $1,949,859 realized in fiscal 2005. The average price of a thousand cubic feet (mcf) of natural gas increased 38% to $8.65 and production decreased 25% to 231,811 mcf.

     Production from existing wells is anticipated to continue to decrease in the future due to normal well depletion. Marine has no input with the operators regarding future drilling operations which could impact Marine’s future oil and natural gas production.

     Weather was the primary cause of the decline in oil and natural gas royalties in fiscal 2006. There were two major hurricanes in the Gulf of Mexico during the fiscal year ended June 30, 2006. Some wells were lost due to the hurricanes. Other wells were off production for most of the quarter that ended December 31, 2005 and did not start recovering until the quarter that ended March 31, 2006. Revenues for the first, second and third quarters of fiscal 2006 were down 34%, 45%, and 20%, respectively, from the revenue realized in the fourth quarter of fiscal 2005.

     Capital Resources and Liquidity. Because of the nature of Marine as a trust entity, there is no requirement for capital. Marine’s only obligation is to distribute to unitholders the net income actually collected net of general and administrative cost. As an administrator of oil and natural gas royalty properties, Marine collects income monthly, pays expenses of administration, and disburses all net income collected to its unitholders each quarter. Because all of Marine’s revenues are invested in liquid funds pending distribution, Marine does not experience liquidity problems.

     Marine’s Indenture (and the charter and by-laws of MPC) expressly prohibits the operation of any kind of trade or business. Marine owns an interest in oil and natural gas properties which are depleting assets. Marine cannot acquire new or additional interests due to the prohibition against these investments. Because of these restrictions, Marine does not require short term or long term capital. These restrictions, along with other factors, allow Marine to be treated as a grantor trust; thus all income and deductions of Marine, for tax purposes, should

flow through to each individual unitholder. Marine is not a taxable entity. However, MPC is a taxable entity and pays state and federal taxes on its income, excluding the 98% net profits interest to be distributed to Marine and deducting statutory depletion.

     Marine does not currently have any long term contractual obligations. Marine has not participated in any off-balance sheet arrangements.

ITEM 7A.		QUANTITATIVE AND QUALITATIVE DISCLOSURES ABOUT MARKET RISK

     As described elsewhere herein, Marine’s only function is to collect overriding royalties from leases operated by others and distribute those royalties to its unitholders after paying the cost of collection and administration. Marine’s income is highly dependent on the prices realized from the sale of oil and natural gas. Oil and natural gas prices have historically experienced significant volatility. Marine does not attempt to manage its commodity price risk through the use of fixed price contracts or financial derivatives.

     Due to the short length of time between receipts and disbursements, cash held by Marine is held in a non-interest bearing trust account.

     Oil and natural gas royalties received by MPC prior to payment of the 98% net profits interest are held in money market accounts that invest in U.S. Treasury securities and are considered not at risk.

     The retained earnings of MPC are held in either money market accounts or U.S. Treasury or agency securities to be held to maturity. Funds held in money market accounts and U.S. Treasury securities that mature in less than one year are considered not at risk.

ITEM 8.		FINANCIAL STATEMENTS AND SUPPLEMENTARY DATA

ITEM 9.		CHANGES IN AND DISAGREEMENTS WITH ACCOUNTANTS ON ACCOUNTING AND FINANCIAL DISCLOSURE

     During fiscal years 2007 and 2006, there have been no disagreements between Marine and its independent registered public accounting firm on accounting or financial disclosure matters which would warrant disclosure under Item 304 of Regulation S-K.

ITEM 9A.		CONTROLS AND PROCEDURES

     As of the end of the period covered by this Annual Report on Form 10-K, the Trustee carried out an evaluation of the effectiveness of Marine’s disclosure controls and procedures (as defined in Rules 13a-15(e) and 15d-15(e) under the Securities Exchange Act of 1934). Based upon that evaluation, the Trustee concluded that Marine’s disclosure controls and procedures were effective as of the end of the period covered by this Annual Report on Form 10-K.

     There has not been any change in Marine’s internal control over financial reporting that occurred during Marine’s last fiscal quarter that has materially affected, or is reasonably likely to materially affect, Marine’s internal control over financial reporting.

MARINE PETROLEUM TRUST AND SUBSIDIARY

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS
Three Years Ended June 30, 2007

(1)		Summary of Significant Accounting Policies

   (a) General

     The Marine Petroleum Trust (“Marine”) was established on June 1, 1956 with the transfer of property to Marine consisting of certain contract rights, units of beneficial interest and common stock in exchange for units of beneficial interest in Marine. The contract rights entitled Marine to receive a .0075 overriding royalty interest in oil, natural gas and other mineral leasehold interests acquired by Gulf Oil Corporation, now Chevron U.S.A., Inc. (“Chevron”), a subsidiary of Chevron Corporation, in certain areas of the Gulf of Mexico prior to January 1, 1980.

     Marine must distribute all income, after paying its liabilities and obligations, to the unitholders during the months of March, June, September and December each year. Marine and its subsidiary cannot engage in a trade or business. Funds held by the subsidiary pending distribution to Marine are invested in U.S. Treasury and agency bonds.

     A Louisiana trust can only exist for a short period of time; therefore, the unitholders assigned their contract rights off-shore of Louisiana to Marine Petroleum Corporation, a wholly-owned subsidiary of Marine, (“MPC”) reserving a 98% net profits interest to themselves. The net profits interest contract was transferred to Marine along with the other properties. Marine is authorized to pay expenses of MPC should it be necessary.

     Marine is to continue until June 1, 2021, or until such later date as holders of the units owning a majority of the outstanding units may designate, but in any event, not more than 20 years from such designation. However, the unitholders owning eighty percent (80%) of the outstanding units may terminate the trust on any date.

   (b) Principles of Consolidation

     The consolidated financial statements include Marine and its wholly-owned subsidiary, MPC. All material intercompany accounts and transactions have been eliminated in consolidation.

   (c) Producing Oil and Gas Properties

     At the time Marine was established, no determinable market value was available for the assets transferred to Marine; consequently, nominal values were assigned. Accordingly, no allowance for depletion has been computed.

     All income from oil and natural gas royalties relate to proved developed oil and natural gas reserves.

   (d) Undistributed Income

     Marine’s indenture agreement provides that the corporate trustee is to distribute all cash in the trust, less an amount reserved for the payment of accrued liabilities and estimated future expenses, to unitholders of record on the 28^th day of March, June, September and December of each year. If the 28^th falls on a Saturday, Sunday or legal holiday, the distribution is payable on the immediately preceding business day. Undistributed income includes $900,356 and $897,051 applicable to MPC at June 30, 2007 and 2006, respectively.

   (e) Federal Income Taxes

     No provision has been made for federal income taxes on Marine’s income since such taxes are the liability of the unitholders.

MARINE PETROLEUM TRUST AND SUBSIDIARY

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS — (Continued)
Three Years Ended June 30, 2007

     Federal income taxes have been provided on the income of MPC, excluding the 98% net profits interest to be distributed to Marine and deducting statutory depletion. MPC uses the cash method of reporting for federal income taxes.

     The primary difference between the effective tax rate of the Trust and the statutory tax rate is the fact that only MPC income, excluding the 98% net profits interest, is subject to federal income tax.

   (f) Credit Risk Concentration and Cash Equivalents

     Financial instruments which potentially subject Marine and MPC to concentrations of credit risk are primarily investments in cash equivalents, U.S. Treasury and agency bonds and receivables. Marine and MPC place their cash investments with financial institutions or companies that management considers credit worthy. Marine has not experienced significant problems collecting its receivables in the past.

     Marine and MPC had cash equivalents of $1,636,082 and $1,454,283 at June 30, 2007 and 2006, respectively, which consisted of cash deposits, U.S. Treasury and agency bonds, and money market mutual funds. For purposes of the statements of cash flows, Marine considers all investments with initial maturities of three months or less to be cash equivalents.

   (g) Statements of Cash Flows

     MPC made federal income tax payments of $14,150 and $7,000 in the years ended June 30, 2007 and 2006, respectively.

   (h) Fair Value of Financial Instruments

     Marine and MPC define the fair value of a financial instrument as the amount at which the instrument could be exchanged in a current transaction between willing parties. The carrying value of cash equivalents, oil and natural gas royalties receivable, receivables from affiliates, accounts payable, and taxes payable approximate fair value because of the short maturities of those instruments.

     U.S. Treasury and agency bonds held to maturity are valued at amortized cost.

   (i) Use of Estimates

     Management of Marine and MPC has made a number of estimates and assumptions relating to the reporting of assets and liabilities and the disclosure of contingent assets and liabilities to prepare these financial statements in conformity with generally accepted accounting principles. These estimates include royalty earned but not yet remitted by the operators. Actual results could differ from those estimates.

(2)		Investment in and Receivables from Affiliate — Tidelands Royalty Trust “B”

     At June 30, 2007 and 2006, Marine owned 32.63% of the outstanding units of interest in Tidelands Royalty Trust “B” (“Tidelands”). The 452,366 units owned by Marine had a quoted market value of $10,978,923 and $4,862,935 at June 30, 2007 and 2006, respectively.

     Marine and Tidelands share certain common costs which are allocated between them based on their respective net revenues.

(4)		Supplemental Information Relating to Oil and Gas Reserves (Unaudited)

     Oil and natural gas reserve information relating to Marine’s and Tidelands’ royalty interests is not presented because such information is not available to Marine or Tidelands. Marine’s share of oil and natural gas produced for its royalty interests and Marine’s equity in oil and natural gas produced for Tidelands’ royalty interests were as follows:

		2007				2006				2005
Marine:
Oil (barrels)			42,260				35,336				49,132
Gas (mcf)			292,326				231,811				309,951
Tidelands:
Oil (barrels)			2,466				1,816				2,627
Gas (mcf)			152,936				41,424				94,703

(5)		Texas Margin Tax

     Texas does not impose an income tax. Therefore, no part of the income produced by Marine is subject to an income tax in Texas. However, corporations and limited liability companies (regardless of how taxed for federal income tax purposes) doing business in Texas are subject to the Texas franchise tax, for tax years through 2006. Beginning with tax year 2007 (and earlier for certain fiscal year taxpayers), the new Texas margin tax applies to almost all entities with liability protection (including trusts). The Texas margin tax is a significant change in Texas tax law. Trusts that meet certain statutory requirements are generally exempt from the margin tax as a “passive

entity.” Although the income of Marine is passive as it consists primarily of royalty income from certain oil and natural gas leases, there is currently no clear authority that Marine satisfies all the statutory requirements for the exemption for passive entities to apply. Therefore, pending additional legislative action in the 2007 legislative session or the issuance of applicable administrative rules promulgated by the Texas Comptroller, it is uncertain whether Marine would be exempt from the margin tax as a passive entity or subject to the margin tax at the trust level. Approximately 3% of Marine’s royalty income is generated in Texas. If Marine is exempt from the margin tax at the trust level as a passive entity, each Unitholder that is a taxable entity would generally include its share of Marine’s revenues in its margin tax computation. If, however, the margin tax is imposed on Marine at the trust level, each Unitholder would generally exclude its share of Marine’s revenues from its margin tax calculation. Under certain circumstances, Texas inheritance tax may be applicable to property in Texas (including intangible personal property such as the units) of both resident and nonresident decedents.
