Layer: Seismic Water Bottom Anomalies (ID: 24)

Name: Seismic Water Bottom Anomalies

Display Field: TYPE1

Type: Feature Layer

Geometry Type: esriGeometryPolygon

Description: 230,000 sq km of seismic data interpretation mapping over 32,000 seafloor seismic amplitude anomalies in the Gulf of Mexico using 3-D time-migrated seismic surveys. This mapping program means to understand the distribution of natural hydrocarbon seeps and the related benthic fauna, and to characterize other seafloor features related to the geological framework of the seafloor. These areas show anomalously high or low amplitude response over the background response. Four classes of water bottom anomalies interpreted to be caused by hydrocarbon seepage include High-Positive, Low-Positive/Negative, Pockmarks and Water-Column Gas Plumes. Six classes of water bottom anomalies that are non-seep related include Cretaceous, Cretaceous Talus, Fan, Salt, Slump, and Channels. Please visit http://www.boem.gov/Seismic-Water-Bottom-Anomalies-Map-Gallery/ for more information on these anomaly types.
