Methods & Sampling

Nutrient samples were collected from most bottles; all nutrient data developed from samples frozen during the cruise and analyzed ashore; data developed by Burke Hales (OSU).
Sal00 - salinity calculated from primary sensors (C0,T0).
Sal11 - salinity calc. from secondary sensors (C1,T1).
Secondary sensor pair was used in final processing of CTD data for most stations because the primary had more noise and spikes. The primary pair were used for cast# 9,24,48,111 and 150 due to multiple spikes or offsets in the secondary pair.

Operation Detection Limits for Nutrient Concentrations (Units are micromoles per liter):
PO4 Range: 0.003-0.004; Mean = 0.004.
NO3+NO2 Range: 0.04-0.08; Mean = 0.06.
Si(OH)4 Range: 0.13-0.24; Mean=0.16.
NO2 Range: 0.003-0.004; Mean = 0.003.

Instruments

CTD - profiler

Supplied Name: Conductivity, Temperature, Depth

Supplied Description:

CTD measurements taken, CTD unit unidentified

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.

Niskin bottle

Supplied Name: Niskin Bottle

Supplied Description:

Niskin bottle cast used to collect water samples for pigment, nutrient, plankton, etc. analysis

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.
