Description

Methods & Sampling

Dataset acquisition description

Nitrate-nitrite, Phosphate, Silicate, Nitrite

Samples were collected from the ship's rosette. Samples were analyzed shortly after collection at sea using standard spectrophotometric methods (Parsons 1984) on a Lachat QuickChem 8000 Flow Injection Analysis System.

Instruments

CTD - profiler

Supplied Name: Rosette

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.

Lachat QuikChem 8500 flow injection analysis system

Supplied Name: Lachat QuickChem 8000 Flow Injection Analysis System

Supplied Description:

Nutrients were analyzed with a Lachat QuickChem 8000 Flow Injection Analysis System.

Instrument Type

Generic Name: Lachat QuikChem 8500 flow injection analysis system

Acronym: QuikChem 8500

Generic Description:

The Lachat QuikChem 8500 Series 2 Flow Injection Analysis System features high sample throughput and simple, but rapid, method changeover. The QuikChem 8500 Series 2 system maximises productivity in determining ionic species in a variety of sample types, from sub-ppb to percent concentrations. Analysis takes 20 to 60 seconds, with a sample throughput of 60 to 120 samples per hour.
