King Harbor, Redondo Beach 1975-1978

Section Responsible for Processing (Top)


Significance (Top)

This collection was part of a coordinated study of the ecosystem in the King Harbor area (Redondo Beach, California). The study had two main criteria: (1) to separate the influence of Southern California Edison's activities from those of the other man-made and natural stresses in the area; (2) to provide information that can be used to help predict the possible impact of future power generating plants on the southern California marine environment.

Background (Top)

This study was funded by Southern California Edison. Dale Straughan was the principal investigator on the substrate component. She was with the Institute of Marine and Coastal Studies at the University of Southern California. The fish population component of this study was directed by Dr. J. Stevens.

Straughan, Dale. 1975. Influence of Power Generating Facilities on Southern California Coastal Waters. Phase I: Study of Environomental Conditions in King Harbor April 1, 1974 - March 31, 1975. Report on the Field Biology. Submitted to Southern California Edison.

Collection Location and Dates (Top)

King Harbor is located near the southern end of Santa Monica Bay, close to the mouth of the Redondo Canyon. Samples were collected between September 1975 to August 1978. The substrate component was divided into four categories:

1. Intertidal unstable substrate (sandy beaches)
2. Subtidal unstable substrate (benthic sediments)
3. Intertidal stable substrate (rock and concrete walls and piers)
4. Subtidal stable substrate (rock and concrete walls and piers)

Taxonomic Contents (Top)

Vermetid mollusks, bivalves, gastropods, polychaetes, crustaceans, echinoderms, tunicates, algae.

Documentation (Top)

There is no auxiliary hard copy documentation for these specimens. All data is contained on the specimen labels.

Description of Collection (Top)

The collection is presently preserved in 70% ethanol. The original fixative was formalin for the algae samples. The collection is housed on the MBPC shelves in the LACM Polychaete Collection Range.

Collection Inventory (Top)

Thirty seven of the sixty two lots contain unsorted vermetid mollusks with some crustaceans, polychaetes and echinoderms. There are two gallon jars of tunicates and twenty one lots are primarily algae samples mixed with invertebrates. Two additional lots are polychaetes and crustaceans sorted into vials.

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.
