Organization, Consolidation and Presentation of Financial Statements [Abstract]
Basis of Presentation	NOTE 1 – BASIS OF PRESENTATION Organization Odyssey Marine Exploration, Inc. and subsidiaries (the "Company," "Odyssey," "us," "we" or "our") is engaged in deep-ocean exploration. Our innovative techniques are currently applied to mineral exploration and other marine survey and exploration charter services. Our corporate headquarters are located in Tampa, Florida. Summary of Significant Accounting Policies This summary of significant accounting policies of the Company is presented to assist in understanding our financial statements. The financial statements and notes are representations of the Company’s management who are responsible for their integrity and objectivity and have prepared them in accordance with our customary accounting practices. Recent Accounting Pronouncements Accounting standards adopted In August 2020, the Financial Accounting Standards Board ("FASB") issued Accounting Standards Update ("ASU") No. 2020-06, Debt-Debt with Conversion and Other Options (Subtopic 470-20) and Derivatives and Hedging-Contracts in Entity’s Own Equity (Subtopic 815-40). The amendments in this Update are effective for public business entities that meet the definition of a Securities and Exchange Commission ("SEC") filer, excluding entities eligible to be smaller reporting companies as defined by the SEC, for fiscal years beginning after December 15, 2021, including interim periods within those fiscal years. For all other entities, the amendments are effective for fiscal years beginning after December 15, 2023, including interim periods within those fiscal years. Early adoption is permitted, but no earlier than fiscal years beginning after December 15, 2020, including interim periods within those fiscal years. The Board specified that an entity should adopt the guidance as of the beginning of its annual fiscal year. The amendments in the above Update affect entities that issue convertible instruments and/or contracts in an entity’s own equity. For convertible instruments, the instruments primarily affected are those issued with beneficial conversion features or cash conversion features because the accounting models for those specific features are removed. However, all entities that issue convertible instruments are affected by the amendments to the disclosure requirements in this Update. For contracts in an entity’s own equity, the contracts primarily affected are freestanding instruments and embedded features that are accounted for as derivatives under the current guidance because of failure to meet the settlement conditions of the derivatives scope exception related to certain requirements of the settlement assessment. The Board simplified the settlement assessment by removing the requirements (1) to consider whether the contract would be settled in registered shares, (2) to consider whether collateral is required to be posted, and (3) to assess shareholder rights. Those amendments also affect the assessment of whether an embedded conversion feature in a convertible instrument qualifies for the derivatives scope exception. Additionally, the amendments in this Update affect the diluted EPS calculation for instruments that may be settled in cash or shares and for convertible instruments. We have adopted this ASU as of January 1, 2022. On October 31, 2018, the SEC adopted a final rule ("New Final Rule") that will replace SEC Industry Guide 7 with new disclosure requirements that are more closely aligned with current industry and global regulatory practices and standards. Companies must comply with the New Final Rule for the company’s first fiscal year beginning on or after January 1, 2021. We adopted this New Final Rule on January 1, 2021. Other recent accounting pronouncements issued by the FASB, the AICPA and the SEC did not or are not believed by management to have a material effect, if any, on the Company’s financial statements.
