Deep Ocean Mining Evironmental Study

Section Responsible for Processing (Top)


Significance (Top)

This is an invaluable collection of specimens from abyssal areas of the North Equatorial Pacific Ocean.

Background (Top)

Multiple studies of the deep-sea fauna have been done in the Clipperton-Clarion Fraction Zone in or near manganese nodule mining claims to provide baseline information on community structure and for future assessment of changes caused by mining. Polychaetes from PRA and ECHO I were sent to Dr. Kirk Fitzhugh, NHMLAC Curator of Polychaetes, for identification and were retained for the collection. Additional material from DOMES is currently on loan to the Polychaete Section.
DOMES (Deep Ocean Mining Environmental Study)
Site A (8°27'N, 150°47'W, 4842-5283 m), Site B (11.7N, 138.4W, 4830-5001 m.), Site C (15°N, 125°W, 4183-4660 m.).
PRA (or BEPRA) - Baseline Evaluation of Provisional Interim Preservation Reserve Area .
12°57'N, 128°19.5'W, 4700-4900 m, October 1989, 16 box cores. PRA sites are meant to be stable reference areas that will not be affected by mining activities and will serve as controls. Samples washed with 25% ethanol in 300 micron mesh screens, stained with Rose Bengal dye, then preserved in 80% ethanol. All animals removed from sediment and nodules. Polychaetes identified by Dr. Kirk Fitzhugh, NHMLAC, and retained for museum.
ECHO I (name refers to original cruise focus of acoustic backscatter from nodule fields)
14°40'N, 125°25'W, 4480-4567m, June 1983, 16 box cores. Study compared the benthos from two adjacent sites, one which had been disturbed 5 years earlier by manganese nodule dredging and one control. Screened sediments and associated fauna were fixed in 4% buffered formaldehyde-seawater, washed in fresh water, preserved in 80% ethanol. Nodule fauna kept separate, most were originally fixed in 4% formaldehyde solution but a few went into either 2% gluteraldehyde-water or 85% ethanol.

Description of Collection (Top)

Wet preserved collection. Some samples originally fixed in 4% buffered formaldehyde-seawater, some in 80% ethanol, later rinsed in fresh water and transferred into 70-80% ethanol.

Collection Inventory (Top)

None at present. Specimens are presently separated by taxon and held as a subcollection on the survey shelves.

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
12/31/2014 0% 0% 0% 100%

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.

Most of the specimens will need to be placed into double-vialed containers.

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.
12/31/2014 0% 0% 95% 5%

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.
