Methods & Sampling

Hydrographic data were collected during casts with a CTD-rosette system (SBE11plus) equipped with a fluorometer, transmissometer, oxygen sensor, and a PAR sensor.

Data Processing Description

Data Processing:Data were processed using SeaSave v 7.26.7.107. See Supplemental File "EN640_CTD_Sea-Bird_File_Header" (PDF) for a representative file header, which includes the SeaSave processing steps. Refer to Supplemental File "EN640_CTD_Data_Notes" (PDF) for Excel processing notes.

BCO-DMO Processing:
- converted date/time fields to ISO8601 format;
- renamed fields to comply with BCO-DMO naming conventions.

Niskin bottle

Supplied Name:

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.
