California Abyssal Collection 1973

Section Responsible for Processing (Top)


Significance (Top)

This is a deepwater San Diego Trough and Santa Catalina Basin collection and comes to NHMLAC via Pete Jumars.

Background (Top)

Selected publications resulting from this collection include:

Jumars, P.A. 1978. Spatial autocorrelation with RUM (Remote Underwater Manipulator): vertical and horizontal structure of a bathyal benthic community. Deep-Sea Research 25: 589-604.

Jumars, P.A. 1975. Environmental grain and polychaete species' diversity in a bathyal benthic community. Marine Biology 30: 253-266.

Collection Location and Dates (Top)

Sampling in the San Diego Trough was carried out during October and November of 1973 as part of the Expedition QUAGMIRE. RUM (Remote Underwater Manipulator) was used to collect core samples.

Taxonomic Contents (Top)

Collecting emphasis was mostly on meiofauna.

Documentation (Top)

Jumar's thesis as well as station and specimen information resides in the Polychaete Collection Manager's office. Some of the samples from his thesis work went to the Scripps Research Institute.

Description of Collection (Top)

The bulk of the collection contains unsorted meiofauna, 20% of the collection is composed of glass vials in jars and identified to some taxonomic level (phylum, class, family or species). Collection is stored in ethanol in the LACM Polychaete Collection Range (basement).

Collection Inventory (Top)

There are 112 jars containing glass vials organized by station. Each jar contains anywhere from 3 - 70 vials and the contents are sorted to some taxonomic level (phylum, class, family, or species). The remaing 484 jars are unsorted meiofauna (material not separted from sediment), presumably fixed in formalin, now stored in ethanol.

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
01/28/2003 0% 0% 0% 100%
08/29/2001 0% 10% 10% 80%
Leslie Harris notes that jars are adequate and contain "good" alcohol. Presumably alcohol was recently replaced.

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.
08/29/2001 0% 0% 0% 100%
Leslie Harris indicates that collection is in "adequate" jars. Reassess that these are museum grade jars and that they have appropriate closures.

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.
02/13/2003 0% 0% 88% 12%
08/29/2001 0% 0% 100% 0%
Leslie Harris indicates "that label data is minimal and needs to be replaced." Presumably label condition is adequate, however, label content needs be addressed.
08/29/2001 0% 2% 88% 10%

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.
