Knudsen-Gorsline 1953-1955

Section Responsible for Processing (Top)


Significance (Top)

Worms from Baja California.

Background (Top)

Jens Knudsen, a graduate student studying crabs under Dr. John Garth at the Allan Hancock Foundation, University of Southern California, made several trips to Baja California. On at least one trip he was accompanied by Donn Gorsline, a grad student in the Department of Geology, USC. Specimens they collected were brought back for the Allan Hancock Foundation collections. The Polychaete Section has field records of 70 sites where Knudsen collected worms in September 1953 and January-February 1955. Dr. Olga Hartman first identified them to family, genus, or species level. Later, Dr. Kristian Fauchald re-identified them to species. The publications resulting from his thesis concentrated on families with jaws (Onuphidae, Eunicidae, Lumbrineridae, Iphitimidae, Arabellidae, Lysaretidae, Dorvilleidae) and deep water species. Most of the Knudsen-Gorsline specimens have not been cited.

Collection Location and Dates (Top)

Pacific and Gulf coasts of Baja California, Mexico. September 1953 and January-February 1955.

Taxonomic Contents (Top)

Polychaetes. (Crustaceans and possibly specimens from other phyla also at the NHMLAC.)

Documentation (Top)

Electronic spreadsheet with station data and original paper data sheets held in the Polychaete Office.

Description of Collection (Top)

Wet preserved collection. Specimens originally fixed in 5% formalin, later rinsed in fresh water, and transferred in 70% ethanol. After identification by Hartman and Fauchald they were put into separate vials. These were placed into taxa jars and incorporated into the general collection while at AHF.

Collection Inventory (Top)

Approximately 450 individuals lots.

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
03/18/2014 0% 0% 0% 100%
Unknown, but probably 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.
03/18/2014 0% 0% 100% 0%
Unknown, but specimens probably need to be double-vialled.

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.
03/18/2014 0% 100% 0% 0%
Unknown, but almost certainly pencil or india ink on paper.

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.
03/18/2014 100% 0%
Unknown, but almost certainly minimal.

Level of Taxonomic Identification (Top)

03/18/2014 0% 100% 0% 0% 0% 0% 0%
Lowest possible taxonomic level.
