Crustacea / Southern California Coastal Water Research Project / 60 m Survey

Section Responsible for Processing

MBC

Significance

This survey identified possible control areas for contrast with existing municipal wastewater discharge sites and was to define the apparent normal variations in the chemistry and biology of the fine sediment areas covering much of the mainland shelf.

Background

Sponsored by the Southern California Coastal Water Research Project (SCCWRP).

Collection Location and Dates

Seventy-one benthic infaunal samples, 71 chemistry samples, 53 trawl samples, and 67 water quality samples were taken at 71 stations between Point Conception, California and the U.S./Mexico border between 28 April and 9 August 1977. The stations were located at intervals of approximately 10 km along the 360 km of coastline at a depth of approximately 60 meters. See map for the station locations.

Taxonomic Contents

Over 37,000 specimens representing 710 species of animals were found in the 71 biological grab samples taken during this survey. Generally, the fauna was dominated by polychaetes (303 species), crustaceans (194 species), molluscs (135 species) and echinoderms (30 species). The 53 trawl samples taken in this survey contained over 23,500 specimens of vertebrates (representing 64 species and 22 families of sharks, rays and bony fishes) and nearly 20,400 specimens of invertebrates (representing 224 species). The most abundant species were the following:
Urchin, Lytechinus anamesus 10,801 (no. of individuals)
Stripetail rockfish, Sebastes saxicola 8,074
Pacific sanddab, Citharichthys sordidus 5,895
Ridgeback prawn, Sicyonia ingentis 5,663
Calico rockfish, Sebastes dalli 2,812
Plainfin midshipman, Porichthys notatus 1,507
Sandstar, Astropecten verrilli 1,478
Speckled sanddab, Citharichthys stigmaeus 1,076
Tellowchin sculpin, Icelinus quadriseriatus 736

Documentation

Most materials about these collections which are available from the Polychaetes library shelves have been scanned and OCR’d. Refer to the Collection Images below for PDFs.

Description of Collection

These wet preserved specimens were originally fixed in 10% formalin and stored in 70% ethanol. The collection has been sorted to phylum or order, transferred to cotton stoppered vials and incorporated into the appropriate invertebrate section’s holdings.

Collection Inventory

The collection was originally contained in approximately 12 small cardboard boxes each containing 120 vials. It has been curated and incorporated into the appropriate taxonomic collections.
