Abstract
The REMOTS Digital SPI can be utilized to measure awide variety of features, including:· Grain size· Small-scale surface boundary roughness· Dredged material thickness· Apparent redox potential discontinuity depth (aRPD)· Subsurface methane gas pockets· Surface microbial aggregations· Infaunal successional stageIt has been used to detect changes in the benthos related to sewage orthermal plume discharge, and mapped habitat and sediment quality aswell as anaerobic regions of the sea floor.The combination of side-scan sonar and the SedimentProfiling Camera has proven effective as a rapid reconnaissancesurveying technique when a client requires detailed information aboutlarge-scale topographic features.
