High-Resolution Autonomous Underwater Vehicle (AUV) Geophysical Survey of a Large, Deep Water Pockmark Offshore Nigeria

P056 HIGH-RESOLUTION AUTONOMOUS UNDERWATER VEHICLE (AUV) GEOPHYSICAL SURVEY OF A LARGE DEEP WATER POCKMARK OFFSHORE NIGERIA 1 ERIC CAUQUIL 1 LAURENT STEPHANE 1 ROBERT A. “TONY” GEORGE 2 and JIH-PING SHYU 2 1. Introduction : This paper presents results of a deepwater pockmark detailed investigation from a geophysical and geomorphologic point of view. AUV high-resolution results are compared to seabed and sub-seabed imagery from 3D exploration data and provide new insights with regard to pockmark generation and fluid migration. Since their first description in the early seventies (King and MacLean 1970) pockmarks have been observed and analyzed almost in all
