Description: High-positive amplitude anomalies which have not yet been confirmed as seep-site hardgrounds – they are purely seismic interpretations. Due to the coarse vertical resolution of 3-D seismic (~30 feet), some of the high-positive anomalies visited by ROVs or submersibles have not had exposed authigenic carbonates at the seafloor due to soft sediment cover. There may be 28 feet of authigenic carbonate buried by 2 feet of hemipelagic mud, but the 3-D seismic amplitude will still show a strong high-positive anomaly.
