Abstract
Analysis of side-scan sonar, subbottom profiler, processed sparker, and fathometer data (approximately 5060 km) from the 136 blocks in the proposed Outer Continental Shelf Lease Sale 49 disclosed features that are potential geologic hazards to oil and gas exploration and development operations. These potential hazards are past mass sediment movement (slumping or sliding) in parts or all of 57 proposed lease sale blocks (27 of which are virtually covered by slumped materials), shallow gas deposits in three proposed lease sale blocks, and recent shallow faulting in one proposed lease sale block.
Other features considered merely to be developmental constraints can be accommodated by existing standard design and engineering technology: erosion and scour, sand waves, filled channels, acoustically turbid zones (gassy sediments), lagoonal sediments, potentially unstable slopes (due to gradient), unidentified bottom objects, and a shipwreck.
