Description

Dissolved Organic Matter, nutrients and CTD data are reported by Dennis Hansell of the Rosenstiel School of Marine & Atmospheric Science (RSMAS), University of Miami.

Methodology: none provided with data; see Li and Hansell (2008)

DMO note: the original data file included Type B (B indicates bottle sample) and bottom depth reported as 700 meters for all stations (the target depth of the casts); depth_n added to enable merge with bottle data. Parameter quality flags are integer values ranging from 0 through 8: 0 is very good; 1 is OK; 4 is questionable; 8 is bad.

Instruments

CTD Sea-Bird SBE 911plus

Supplied Description:

Instrument Type

Generic Name: CTD Sea-Bird SBE 911plus

Acronym: CTD SBE 911plus

Community Identifier: http://vocab.nerc.ac.uk/collection/L22/current/TOOL0058/

Generic Description:

The Sea-Bird SBE 911 plus is a type of CTD instrument package for continuous measurement of conductivity, temperature and pressure. The SBE 911 plus includes the SBE 9plus Underwater Unit and the SBE 11plus Deck Unit (for real-time readout using conductive wire) for deployment from a vessel. The combination of the SBE 9 plus and SBE 11 plus is called a SBE 911 plus. The SBE 9 plus uses Sea-Bird's standard modular temperature and conductivity sensors (SBE 3 plus and SBE 4). The SBE 9 plus CTD can be configured with up to eight auxiliary sensors to measure other parameters including dissolved oxygen, pH, turbidity, fluorescence, light (PAR), light transmission, etc.). more information from Sea-Bird Electronics

Niskin bottle

Supplied Name: Niskin Bottle

Supplied Description:

Instrument Type

Generic Name: Niskin bottle

Community Identifier: http://vocab.nerc.ac.uk/collection/L22/current/TOOL0412/

Generic Description:

A Niskin bottle (a next generation water sampler based on the Nansen bottle) is a cylindrical, non-metallic water collection device with stoppers at both ends. The bottles can be attached individually on a hydrowire or deployed in 12, 24, or 36 bottle Rosette systems mounted on a frame and combined with a CTD. Niskin bottles are used to collect discrete water samples for a range of measurements including pigments, nutrients, plankton, etc.

Acronym: Shimadzu TOC-V

Community Identifier: http://onto.nerc.ac.uk/CAST/124

Generic Description:

A Shimadzu TOC-V Analyzer measures DOC by high temperature combustion method.
