Display Field: Feature

Type: Feature Layer

Geometry Type: esriGeometryPolygon

Description: Former seep_anomaly_positives polygons that the 3-D seismic vertical profiles show clear subsurface migration pathways to the seafloor, but subsequent visual investigations by manned submersible, ROV, or AUV (by government, academia, and/or industry) indicate that there are no exposed carbonates at the site, and/or remote sensing by multibeam or sidescan show no elevated acoustic backscatter, suggesting the presence of buried authigenic carbonates. Though clear seafloor indications of seepage such as bacterial mats (e.g., Beggiatoa) and/or brine seeps may be present, no suitable substrates for megafauna such as corals or chemosynthetic organisms (e.g., tubeworms, mussels, etc) such as hardgrounds are present. If shown to be buried by any of these methods above, the anomalies in question will be removed from the list of potential hard substrates suitable for benthic organisms and the 2000’ buffer to protect any communities are removed.
