Description

Organic matter and nutrients including del-15N, del-13C, POC and POM from EDDIES Oceanus cruises are reported by Dennis Hansell of the Rosenstiel School of Marine & Atmospheric Science (RSMAS).

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

OCB 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.

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.
