    • Seismic Water Bottom Anomalies

    Symbology (.lyrx)

    Since 1998, geoscientists at the Bureau of Ocean Energy Management (BOEM) have identified and mapped water bottom (seafloor) acoustic amplitude anomalies in the deep-water Gulf of America (GOA) using 3-D time-migrated seismic surveys. The purpose of this mapping program is to understand the distribution of natural hydrocarbon seeps and related benthic fauna (chemosynthetic and coral communities) in the GOA, and to characterize other seafloor features related to the geological framework of the seafloor. These areas show anomalously high or low acoustic amplitude response relative to typical background, with most areas having overlapping seismic coverage by two or more surveys. These results cover over 230,000 square kilometers of seismic data interpretation.
