Description

Methods & Sampling

Dataset acquisition description

All methods were standard JGOFS procedures (nutrients, particulate matter concentrations). Nutrient samples were frozen and returned to the US for analyses; chlorophyll determinations were completed at sea using fluorometry. Particulate organic carbon/nitrogen samples were filtered, dried at 60C, and returned to the US for analysis on an elemental analyzer. Complete details can be found in Smith et al. (2006, 2011a,b).

Data Processing Description

Dataset Processing Description

BCO-DMO Processing Notes:
- added conventional header with dataset name, PI name, version date
- modified parameter names to conform with BCO-DMO naming conventions
- reformatted date so all seasons are same: mm/dd/yyyy
- reformatted time to HHMM from HMM
- added column 'season'

Supplied Description:

Instrument Type

Generic Name: CTD - profiler

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

Generic Description:

The Conductivity, Temperature, Depth (CTD) unit is an integrated instrument package designed to measure the conductivity, temperature, and pressure (depth) of the water column. The instrument is lowered via cable through the water column. It permits scientists to observe the physical properties in real-time via a conducting cable, which is typically connected to a CTD to a deck unit and computer on a ship. The CTD is often configured with additional optional sensors including fluorometers, transmissometers and/or radiometers. It is often combined with a Rosette of water sampling bottles (e.g. Niskin, GO-FLO) for collecting discrete water samples during the cast.

This term applies to profiling CTDs. For fixed CTDs, see https://www.bco-dmo.org/instrument/869934.
