SCHEDULE 13D

Preliminary Statement

This filing amends a Schedule 13D filed by The Laitram Corporation, the predecessor of Laitram, L.L.C., a Louisiana limited liability company (“Laitram”) on March 25, 1999 and amendments thereto filed on April 28, 2003, January 13, 2004, July 2, 2004, March 23, 2005, December 8, 2015, September 12, 2016 and October 5, 2016, and a Schedule 13D filed by James M. Lapeyre, Jr. on February 4, 1999 and amendments thereto filed on April 28, 2003, January 13, 2004, July 2, 2004, March 23, 2005, December 8, 2015, September 12, 2016 and October 5, 2016. Information in this Amendment No. 8 to the Schedule 13D is presented as of November 3, 2016.

This filing relates to equity securities of ION Geophysical Corporation, a Delaware corporation (“ION”). Only the amendments to the Schedules listed above resulting from the transactions reported in Item 5 and from events occurring after October 4, 2016 are reproduced below. On February 4, 2016, ION completed a one-for-fifteen reverse stock split. Information in this Amendment No. 8 to the Schedule 13D is presented as adjusted for the reverse stock split. For a discussion of prior acquisitions and related matters, please see each original Schedule 13D and the amendments thereto.

James M. Lapeyre, Jr. is the President of Laitram. He is also a director of ION and Chairman of its Board of Directors. As a director of ION, Mr. Lapeyre may take an active role in corporate strategy and business decisions involving ION. As a precautionary measure, Mr. Lapeyre and Laitram have elected to file this Statement on Schedule 13D rather than Schedule 13G given Mr. Lapeyre’s role as Chairman of the Board of ION, and in case Mr. Lapeyre’s actions in his capacity as an ION director are attributed to Laitram or should Laitram, as a shareholder of ION, be a participant in a transaction involving ION. The election to file on Schedule 13D shall not be deemed an acknowledgment or admission by Laitram that the actions of Mr. Lapeyre are attributable to Laitram, and Laitram hereby disclaims any such actions by Mr. Lapeyre. The election to file on Schedule 13D shall not be deemed an acknowledgment or admission by Mr. Lapeyre or Laitram that such a statement is required to be filed pursuant to Section 240.13d-1(e), or otherwise, or that Mr. Lapeyre or Laitram hold securities of ION with a purpose or effect of changing or influencing the control of ION, or in connection with or as a participant in any transaction having that purpose or effect. The election to file on Schedule 13D shall not be deemed an acknowledgment or admission by Mr. Lapeyre or Laitram that they do not continue to be eligible to file a statement on Schedule 13G, pursuant to Section 240.13d-1(c), as persons who, among other things, have not acquired such securities with any purpose of, or with the effect of, changing or influencing the control of ION, or in connection with or as a participant in any transaction having that purpose or effect.

Mr. Lapeyre, the President of Laitram, is a director of ION and chairman of its Board of Directors. In his capacity with ION, and in keeping with his fiduciary duties as a director, Mr. Lapeyre may from time to time consider, discuss with senior management, and participate in Board deliberations about plans or proposals relating to: the acquisition or disposition of securities of ION; extraordinary corporate transactions involving ION or any of its subsidiaries; selling or transferring a material amount of assets of ION or any of its subsidiaries; changing the present board of directors or management of ION; materially changing the present capitalization or dividend policy of ION; making other material changes in ION’s business or corporate structure; changing ION’s charter, bylaws or instruments corresponding thereto or other actions which may affect control of ION; causing the ION Common Stock no longer to be quoted on the New York Stock Exchange (the “NYSE”); causing ION securities to become eligible for termination of registration pursuant to Section 12(g)(4) of the Securities Exchange Act of 1934, as amended (the “Exchange Act”); or taking any action similar to any of those enumerated above.
