MetadataSymbology (.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.The Bureau of Ocean Energy Management (BOEM) provides the data for use "as is." BOEM provides this information with the understanding that it is not guaranteed to be accurate, correct, or complete and conclusions drawn from such information are the responsibility of the user. While every effort has been made to ensure the accuracy, correctness and timeliness of materials presented within the limits of the current state of the art, BOEM assumes no responsibility for errors or omissions, nor because of the failure of the data to function on a particular system.
