Temporal and spatial variations in infaunal benthic community structure, grain-size composition of sediments, concentrations of hydrocarbons in sediments, and concentrations of total organic carbon, hydrogen, and nitrogen were studied at 14 stations over three sampling seasons. The station design also allowed comparison of gully and nongully environments, and canyon and noncanyon environments at several depths. Megafaunal populations were studied along a transect near the US/Canadian border and along the 2100-m isobath near Lydonia Canyon. Statistical analysis of the infauna indicated four major groups that corresponded to the four depth intervals sampled.
