Tomales Bay 2003-2004

Significance (Top)

In 2003 the National Park Service and Dr. Ted Grosholz (Bodega Marine Lab, UC Davis) organized a rapid assessment biodiversity survey for Tomales Bay, California. The goal was to establish a current inventory of invertebrate species found in the area. Results were incorporated into the Tomales Bay Biodiversity Inventory (http://tomalesbaylife.org/checklists.asp). Polychaete Collections Manager Leslie Harris & Research Associate Don Cadien were part of the field team. Selected inverts, mainly polychaetes & crustaceans, were brought back to NHMLAC to augment our research collections. Additional collections were made by Harris in 2004.

Collection Location and Dates (Top)

Maps of the study area are at http://www.tomalesbaylife.org/maps.htm

Sampling was done in August 2003 and June 2004 and was primarily intertidal.

Taxonomic Contents (Top)

The collection is dominated by polychaetes and crustaceans, with a few lots belonging to other phyla.

Documentation (Top)

Harris' field notes are in the Polychaete Section. Electronic station and species lists are part of the MBPC database.

Description of Collection (Top)

All of the material is wet preserved. Most was fixed with 5-10% formalin, subsequently rinsed in distilled water, and transferred to 70% ethanol for long-term storage. Many crustaceans and molluscs were fixed in 70% ethanol and later transferred to fresh 70% ethanol. A few polychaetes and other taxa were fixed and kept in 95% ethanol for DNA analysis.

A voucher collection was made during 2003 and given to the National Park Service.

Polychaetes were field identified by Harris to genus or species level. The other invertebrates were usually sorted to class or order but some were field identified to species.

Material is currently in the Polychaete Section. After curation, non-polychaetes will be distributed to the appropriate sections.

Collection Inventory (Top)

Three hundred eight-five (385) lots of inverts were identified during the survey. Sixty three (63) lots were either given to the other taxonomists, designated as vouchers, or were in poor condition and discarded. Three hundred twenty-two (322) lots were preserved and brought back to NHMLAC in 2-ml and 5-ml plastic vials. Processing and incorporation into the collections is estimated to be completed June 2009. All of the material is wet preserved. Most was fixed with 5% formalin, rinsed later in distilled water, and transferred to 70% ethanol for long-term storage. Many crustaceans and molluscs were fixed in 70% ethanol and later transferred to fresh 70%. A few polychaetes and others were fixed and kept in 95% ethanol for DNA analysis.

A voucher collection was made during 2003 and given to the National Park Service.

Polychaetes were field identified by Harris to genus or species level. The other invertebrates were usually sorted to class or order but some were field identified to species and separated.

Lots are currently held in the Polychaete Section. After curation is completed, they will be distributed to appropriate sections.

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

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.
