Sediment Profile Imagery
NOAA Office for Coastal Management
This imagery records the nearshore sediment to the depth of camera penetration, as well as the physical, chemical, geological, and biological features of the organisms living on the seafloor. Descriptive attributes of sediment type and character, as well as biological taxa—groups of organisms judged to belong to discrete units—are documented for each sample. These data are useful for quick assessment of bottom character, especially the interface between sediment and water, the presence of methane, the stage of biological succession, and other characteristics. The data are often collected at various locations within a project area, determined by a systematic pattern or local environmental factors (substrate type, depth, etc.).
