Map search display filtered to show recently added three-dimensional (3D) surveys, acquired between 1996 and 1998 within the Gulf of America. These surveys were permitted over 25 years ago and are therefore eligible for public release. The Bureau of Ocean Energy Management protraction areas are labeled.

Perspective view of horizon mapping and fault attribute detection on two combined three-dimensional (3D) volumes located in the Santa Barbara Channel, offshore southern California. The horizons show various marker beds mapped throughout the volumes, providing insights into the 3D deformation patterns.
