San Diego Bay Survey, 2011

Section Responsible for Processing (Top)


Significance (Top)

A collection with good identifications and preserved in 95% ethanol.

Background (Top)

From Sorensen et al 2013: "The purpose of this study was to conduct an ecological index, early detection survey to identify and catalog native and non-indigenous species near naval facilities within the four hydrographic regions in the bay. Work was similar to a Rapid Assessment Survey (RAS) methodology and a team of taxonomists identified live specimens for 5 days. The focus of this study was to identify native, introduced, and cryptogenic species present on multiple natural and artificial habitats within the four hydrographic regions. This overall goal was broken down into four key objectives: (1) to understand and summarize historic data on species distribution, including presence of exotic species within the four management regions of the San Diego Bay; (2) to plan and execute a Rapid Assessment (5-day) Survey using a random sampling strategy to identify species in each of the four hydrographic regions of the Bay (marine, thermal, seasonally hypersaline, and estuarine); (3) to assess feasibility of using DNA barcoding as a tool for augmenting species identification in a rapid assessment platform; and (4) to provide summary of data relative to the four management regions, including species distribution and relative abundance relative to U.S. Navy facilities." Leslie Harris, NHMLAC Polychaete Collections Manager participated in the survey by identifying the polychaetes and retained all the specimens for the collection.

Collection Location and Dates (Top)

San Diego Bay, California, July 2011. 18 sites were sampled prior to and during a Rapid Assessment Survey. Settling plates were deployed the previous year at 17 sites and retrieved during the survey. Soft sediment grabs were taken at 17 sites using a 0.25-m2 van Veen grab deployed from a Boston whaler.

Documentation (Top)

Data files and project report available from Polychaete Section. Official report had not yet been released by the U.S. Navy (12/31//2014).

Description of Collection (Top)

Wet preserved collection. All settling plate specimens were live-sorted and identified, then preserved in 95% ethyl alcohol. Soft sediment specimens were first preserved in 90% ethyl alcohol then sorted and identified.

Collection Inventory (Top)

Approximately 300 lots of polychaetes.

Collection Assets (Top)

No collection assets available.

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.
