Description

Inorganic Carbon Data from two Great Belt cruises in the Southern Ocean

Methods & Sampling

Dataset acquisition description

DIC was determined using a high precision (0.05%CV) small-volume DIC analyzer (~1.5 ml sample size) using an infrared-based instrument (AIRICA; Marianda Co., Germany; Bates et al., 2012) with replicate samples analyzed using a VINDTA 3C system at BIOS. Multiple replicates samples were analyzed and analytical imprecision was less than 0.1% (~2 µmol kg-1). DIC aanalyses were routinely calibrated using seawater Certified Reference Material (CRM) from A.G. Dickson, Scripps Institute of Oceanography, and the accuracy of samples compared to CRM’s was less than 0.1% (~2 µmol kg-1).

Data Processing Description

Dataset Processing Description

DIC was incorporated with bottle ID, and hydrographic data generated by PI Balch (Bigelow Laboratory of Ocean Sciences; BLOS). The DIC data is flagged as 2 (good data) and 5 (missing data; bottle misfire, broken bottle) with -999 placed in the Excel cell.

Instruments

CTD Sea-Bird SBE 911plus

Supplied Name: CTD 911

Supplied Description:

Instrument Type

Generic Name: CTD Sea-Bird SBE 911plus

Acronym: CTD SBE 911plus

Community Identifier: http://vocab.nerc.ac.uk/collection/L22/current/TOOL0058/

Generic Description:

The Sea-Bird SBE 911 plus is a type of CTD instrument package for continuous measurement of conductivity, temperature and pressure. The SBE 911 plus includes the SBE 9plus Underwater Unit and the SBE 11plus Deck Unit (for real-time readout using conductive wire) for deployment from a vessel. The combination of the SBE 9 plus and SBE 11 plus is called a SBE 911 plus. The SBE 9 plus uses Sea-Bird's standard modular temperature and conductivity sensors (SBE 3 plus and SBE 4). The SBE 9 plus CTD can be configured with up to eight auxiliary sensors to measure other parameters including dissolved oxygen, pH, turbidity, fluorescence, light (PAR), light transmission, etc.). more information from Sea-Bird Electronics

Elemental Analyzer

Supplied Name: VINDTA 3C

Supplied Description:

VINDTA 3C

The VINDTA 3C (Versatile INstrument for the Determination of Total inorganic carbon and titration Alkalinity) combines the proven VINDTA alkalinity titration concept with a simplified extraction unit for coulometric dissolved inorganic carbon (DIC) measurement.

Instrument Type

Generic Name: Elemental Analyzer

Community Identifier: http://vocab.nerc.ac.uk/collection/L05/current/LAB01/

Generic Description:

Instruments that quantify carbon, nitrogen and sometimes other elements by combusting the sample at very high temperature and assaying the resulting gaseous oxides. Usually used for samples including organic material.

Niskin bottle

Supplied Name: Niskin Bottle

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.
