Re:      Marine Exploration, Inc.
         Forms 10-K and 10-K/A for Fiscal Year Ended June 30, 2009 Filed
         September 28, 2009 File No 0-24637

Dear Mr. Thompson:

We are in receipt of your correspondence dated March 22, 2010 and our responses
are below. As a result of your comments we have filed the second amendment to
the Marine Exploration, Inc. Annual Report on Form 10-K for the year ended June
30, 2009, to amend for those items discussed below.

Form 10-K/A for Fiscal Year Ended June 30, 2009
- -----------------------------------------------
Consolidated Financial statements, page F-1
- -------------------------------------------
Consolidated Balance Sheets, page F-3
- -------------------------------------

     1.   In future filings please separately report the deficit accumulated
          during the development stage from the deficit accumulated from
          previous business operations. In addition, it appears that the deficit
          accumulated during the devel0pment stage disclosed in the balance
          sheet should agree to the net loss reported from inception of the
          development stage to the end of the most recent year presented in the
          statements of operations. Please revise future filings accordingly or
          advise.

          We have reviewed your comment and will make such revisions to our
          future filings. In future filings the Company will separate the
          deficit accumulated during the development stage from the deficit
          accumulated from previous operations. In addition, the Company notes
          that the deficit accumulated during the development stage of
          $7,099,889 on the balance sheet does not match the corresponding
          figure on the statements of operations of $14,240,460. These figures
          should match at $14,240,460. The discrepancy was due to an unnoticed
          typo error on the balance sheet. The cumulative development stage
          deficit on the balance sheets and statements of operations do match on
          the subsequent two 10-Q's.

Note 6.  Commitments, page F-13
- -------------------------------

     2.   Please revise your disclosure regarding the joint venture to fund
          salvage and treasure recovery operations for the specified projects,
          which appears to be further described in the description of your
          business, to comply with the requirements of EITF 07-1 (FASB ASC
          808-10-50). Your disclosure should clearly describe the following:

          o    The nature and purpose of the arrangement;
          o    Your rights and obligations under the arrangement;
          o    Your accounting policies for the funding provided under the terms
               of the arrangement; and
          o    The income statement classification and amounts attributable to
               transactions arising from the arrangement.

          Please also disclosure the funding provided and the remaining
          obligation as of the most recent balance sheet date. If you have not
          been able to make the required payments, please also disclose whether
          there are any penalties or uncertainties which are reasonably likely
          to result in a loss.

     After review of your comment we have expanded the disclosure in Note 6 in
the Notes to the Financial Statements.

Item 9A. Controls and Procedures Disclosures Controls and Procedures, page 17
- -----------------------------------------------------------------------------

     3.   Please revise the conclusion of your principal executive and financial
          officers regarding the effectiveness of your disclosure controls and
          procedures to state, if true, that your disclosure controls and
          procedures were effective to ensure that information required to be
          disclosures by you in the reports that you file or submit under the
          Exchange Act is recorded, processed, summarized and reported within
          the time periods specified in the Commission's rules and forms and is
          accumulated and communicated to management, including your principal
          executive and principal financial officers, or persons performing
          similar functions, as appropriate to allow timely decisions regarding
          required disclosure. Refer to the definition of disclosure controls
          and procedures in Exchange Act Rule 13a-15(e). Please revise your
          disclosure in future quarterly reports.

          After a review your comment, we have revised our Item 9A to use the
          definition of disclosure controls and procedures as set forth in
          Exchange Act Rule 13a-15(e) and have revised our disclosure to show
          that disclosure controls and procedures were not effective at June 30,
          2009. We will take action to insure such disclosures in our future
          filings are accurate.



                                                                     Page 3 of 4

Internal Controls Over Financial Reporting, page 17
- ---------------------------------------------------

     4.   It does not appear that the financial statement section of your
          document contains the management's report on internal control over
          financial reporting. Please revise to include management's annual
          report on internal control over financial reporting as required by
          Item 308T(a) of Regulation S-K. Please note that since the auditor's
          attestation report is not required pursuant to the temporary rules of
          the Commission, you should provide the disclosure required by Item
          308T(a)(4). In addition, please consider whether management's failure
          to perform or complete its report on internal control over financial
          reporting impacts its conclusions regarding the effectiveness of your
          disclosure controls and procedures as of the end of the fiscal year
          covered by the report and revise your disclosure as appropriate.

          After a review of your comment and our filing we have revised our
          Annual Report on Form 10-K to include management's annual report on
          internal control over financial reporting as required by Item 308T(a)
          of Regulation S-K.

          As a result of this failure to include the disclosure requirements, we
          have determined that our internal controls over financial reporting
          are not effective as discussed in the Amendment No. 2 to our Annual
          Report on Form 10-K.

     5.   Please revise your disclosure to state whether there has been any
          change, as opposed to significant changes, in your internal control
          over financial reporting during the last fiscal quarter, as opposed to
          the fiscal year, that have materially affected, or are reasonably
          likely to materially affect, your internal control over financial
          reporting. Refer to Item 308T9b) of Regulation S-K. In addition,
          please revise your disclosure in future quarterly reports to provide
          the disclosure required by Item 308T(b) of Regulation S-K.

          We have revised our disclosure to state that there were no changes in
          our internal control during the last fiscal quarter, rather than to
          say that there were no significant changes. We will make such
          disclosures in our future quarterly reports.

- -------------------

     6.   The report must also be signed on your behalf by your principal
          executive officer, principal financial officer, controller or
          principal accounting officer, and at least a majority of the board of
          directors. Any person who occupies more than one of the positions
          specified shall indicate each capacity in which he signs the report.
          Please amend the filing to include the appropriate signatures in the
          second signature section of Form 10-K. Refer to general instruction
          D.(2) and the signature section of Form 10-K.

          We have submitted our Amendment No. 2 on Form 10-K signed by our
          principal executive officer, principal accounting officer and at least
          a majority of our Board of Directors.

     7.   It appears the report of your independent registered public accountant
          is incorporated by reference in previously filed registration
          statements. As such, please provide the consent required by Item
          601(b)(23) of Regulation S-K.

     We have removed the exhibit list referencing our previously filed
registration statements.

In addition, we acknowledge the following:

     -    the Company is responsible for the adequacy and accuracy of the
          disclosure in the filing;

     -    staff comments or changes to disclosures in response to staff comments
          do not foreclose the Commission from taking any action with respect
          the filing; and

     -    the Company may not assert staff comments as a defense in any
          proceeding initiated by the Commission or any person under the federal
          securities laws of the United States.

We hope that our responses and the filing of Amendment No. 2 to our Annual
Report on Form 10-K for the year ended June 30, 2009 has satisfied your
concerns. Please let us know if you have any further comments.

                                      Sincerely,

                                      Marine Exploration, Inc.
