Los Angeles County Sanitation District 2006

Section Responsible for Processing

MBC

Significance

These collections were made specifically to get fresh material in good shape for morphological studies and molecular analysis.

Background

The Los Angeles County Sanitation Districts consist of 24 independent districts which collaborate to manage wastewater on a regional scale. The agency maintains a marine biology laboratory to assess the health of the marine environmental impacted by wastewater discharge. Monitoring surveys of fish and benthic invertebrates are conducted on a regular basis as part of the assessment. Museum personnel occasionally participate in these cruises in order to procure new material. This particular collection was made by Leslie Harris (Polychaete Collections Manager).

Collection Location and Dates

Samples were taken from van Veen benthic grabs in Santa Monica Bay, California, on 12 June 2006.

Taxonomic Contents

Most specimens are polychaetes. Some are crustaceans, molluscs, nemerteans, and 1 enteropneust.

Documentation

Electronic files in the Polychaete Section. MBPC 6745-6748 (LACSD 1C, LACSD 7C).

Description of Collection

Wet preserved specimens. They were collected live and brought back to the museum for identification and preservation. Subsamples of selected individuals were put into 95% ethanol and frozen. The rest of the material was relaxed with 7% magnesium chloride-distilled water, fixed in 5% formalin-seawater, rinsed briefly in fresh water, and transferred into 70% ethanol.

Collection Inventory

59 lots total

Curatorial Status (Click to view)

Specimen Condition

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
02/19/2010	0%	0%	100%	0%

Container Condition

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

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

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.
