Sediment profile imagery (SPI) (also known as REMOTS (Rhoads and Germano, 1982)) facilitates the assessment of the biophysical processes that occur in the benthic environment through the acquisition and analysis of high resolution images of vertical sections and surfaces of the seafloor. The SPI apparatus incorporates the use of a 12-megapixel Digital SLR camera to obtain in situ photographs of the first 20 cm of the seafloor. Because the sediment is not disturbed in the process, SPI photographs provide information on the physical and biological components of the seabed that is not readily available using traditional methods. From 2012 to 2019, 17 SPI datasets were acquired at 13 disposal at sea sites in British Columbia to monitor the environmental conditions of the sea floor. SPI & surface photographs, tabular data, and a geodatabase with attachments are provided in zipfolders for each study.
