The specimens identified by the Smithsonian Oceanographic Sorting Center SOSC were collected during numerous cruises ranging from 1962 to 1974. There were 94,724 specimens in the 9,923 lots of collected material all were identified to family level and, where possible, some were identified to genus and species. Specimens were either sized individually or, when numerous, grouped in size classes. Technicians from the Plankton Section of the Smithsonian Oceanographic Sorting Center have been sorting the pelagic marine invertebrates from 758 midwater trawl samples collected for the Naval Oceanographic Office. The sorting, counting, preservation, and labeling of this important collection is now complete. The characterization and distribution of the deepwater pelagic fauna of the marine biosphere is inadequate. Despite years of intensive oceanographic survey, collections of bathypelagic and mesopelagic fauna available for study are insignificant compared to the vast areas from which specimens are unavailable. Our knowledge of fundamental processes of deepwater pelagic environments lags far behind the more complete picture now emerging of the epipelagic and neritic zones. Against this background these midwater trawl samples collected will make a significant contribution to knowledge of the deepwater pelagic fauna.
