Description: An anomalously low-positive amplitude response on seismic compared to the typical hemipelagic muds. The most active and dynamic of this type exhibit a negative amplitude response, or acoustic trough, at the seafloor, resulting from a total phase reversal of the seafloor’s typical positive acoustic impedance. These areas have been observed to have rapid hydrocarbon flux, often with sediment and brine being expulsed with the hydrocarbons.
