Data Processing Description

BCO-DMO Processing:

- added conventional header with dataset name; PI name; version date
- created dataset from list of file names; added cruise_id, event #, station, and cast columns; joined this with eventlog dataset
- created links to .pdf files
- joined this dataset with eventlog v2 dataset to provide date/time/location, etc.

Instruments

CTD Sea-Bird

Supplied Name:

Supplied Description:

ODF 12-place 30 liter Niskin bottle rosette, replaced by ODF 36-place 10 liter Bullister bottle rosette; GT-C unit comprosed of Seabird carousel/CTD with 24 12L GO-FLO bottles.

Instrument Type

Generic Name: CTD Sea-Bird

Community Identifier: http://vocab.nerc.ac.uk/collection/L05/current/130/

Generic Description:

Conductivity, Temperature, Depth (CTD) sensor package from SeaBird Electronics, no specific unit identified. This instrument designation is used when specific make and model are not known. See also other SeaBird instruments listed under CTD. More information from Sea-Bird Electronics.

GO-FLO Teflon Trace Metal Bottle

Supplied Name:

Supplied Description:

12 liters

Instrument Type

Generic Name: GO-FLO Teflon Trace Metal Bottle

Acronym: GO-FLO Teflon TM

Community Identifier: http://vocab.nerc.ac.uk/collection/L05/current/30/

Generic Description:

GO-FLO Teflon-lined Trace Metal free sampling bottles are used for collecting water samples for trace metal, nutrient and pigment analysis. The GO-FLO sampling bottle is designed specifically to avoid sample contamination at the surface, internal spring contamination, loss of sample on deck (internal seals), and exchange of water from different depths.
