Crustacea / Mineral Management Service / Pac Baroness Survey

Section Responsible for Processing (Top)


Significance (Top)

On September 21, 1987, the 564-foot freighter, Pac Baroness, collided in fog with another freighter, theAtlantic Wing, approximately 20km to the southwest of Point Conception, California. As a result of the collision, the Pac Baroness eventually sank in about 450 to 500m of water, at a reported location of approximately 34°21.13'N latitude and 120°38.14'W longitude. The Pac Baroness was carrying a cargo of 21,000 metric tons of finely powered and concentrated copper ore consisting of refined chalcopyrite, covellite and native copper, and containing approximately 30% each of copper, sulfur and iron. The vessel was also carrying approximately 7,500 barrels of intermediate-grade fuel oil and 280 barrels of marine diesel. Batelle Ocean Sciences, through a joint research arrangement with the University of California at Santa Barbara (USCB), conducted a limited environmental study in the vicinity of the wreck, to locate the vessel, determine the extent of initial contamination and examine the potential impact on benthic communities of the immediate surrounding area.

Taxonomic Contents (Top)

Although all common invertebrate taxa were collected, our collections hold only the crustaceans. A total of 40-43 invertebrate species were collected from three control sites and 20-33 species were identified from the three wreck-sites. At the control site 559-736 individuals were collected compared to 137-381 individuals from the wreck-sites. Polychaetes and crustaceans dominated the samples. Molluscs represented the next most abundant taxon (8% of the fauna).

Specimen Condition (Top)

Date 4: New alcohol needed immediately (specimens will otherwise be irreparably damaged) 3: Containers need to be 'topped off' 2: New alcohol needed within next 6-12 months 1: No curation needed at present

Container Condition (Top)

Date 4: Immediate short-term (less than 5 years) storage container replacement needed. Present containers are inadequate. Curate in the short-term with plastic buckets, whirltop bags, or similar. 3: Specimens contained in museum-grade long-term (greater than 5 years) storage containers. Jars need new closures (e.g. replace Bakelite and metal lids). 2: Transfer to museum-grade long-term storage containers. Replace or transfer to new jars and glass vials, replace cotton and closures. 1: Containers are museum-grade and meet highest curation standards.

Label Condition (Top)

Date 4: New labels needed immediately (original labels in poor condition, paper torn/worn, legibility poor). 3: New labels needed within next 1-2 years (original labels beginning to wear, pencil writing fading, low quality paper was used). 2: New labels needed are as a result of curation and accretion of collection. 1: No new labels needed at present.

Label Content (Top)

Date 2: New label or additional label needed because original label data is incomplete and supporting documentation provides additional collection data which greately enhances significance and value of each lot. 1: Label content complete. All collection data are contained on label.
