Instruments

NIWA Underway pCO2 system

Supplied Description:

NIWA Underway pCO2 system

Instrument Type

Generic Name: NIWA Underway pCO2 system

Acronym: pCO2 NIWA

Generic Description:

This partial pressure of carbon dioxide (pCO2) analysis system sampled from the vessel R/V Tangaroa's underway system. The pCO2 was measured by infrared analysis of the carbon dioxide of air continuously equilibrated with pumped seawater. The pCO2 rig was located on a bench in the temperature controlled laboratory off the fish factory, beside the pH systems (continuous and discrete) and the alkalinity system.additional details are available in the SAGE pCO2 Data Report

Thermosalinograph

Supplied Description:

R/V Tangaroa's SBE-21 thermosalinograph

Instrument Type

Generic Name: Thermosalinograph

Acronym: TSG

Community Identifier: http://vocab.nerc.ac.uk/collection/L05/current/133/

Generic Description:

A thermosalinograph (TSG) is used to obtain a continuous record of sea surface temperature and salinity. On many research vessels the TSG is integrated into the ship's underway seawater sampling system and reported with the underway or alongtrack data.

Parameters

Date and time formats are described in python strftime() syntax.
