Deployment-specific acquisition description

Sampling and Analytical Methodology:

Total CO2:
The analysis was done at sea with a Marianda Automated Infra Red Inorganic Carbon Analyzer (AIRICA) couple with a LI-COR LI-7000 CO2/H2O Gas Analyzer. The samples were standardized using Certified Reference Materials (CRMs) provided by Dr. A. Dickson of Scripps Institution of Oceanography. Each 250 mL sample was poisoned with 0.2 mL of mercuric chloride. CRM batch numbers and correction magnitude:
119 (2014.78 ± 0.79 µmol kg-1)
Method Reference: Mathis et al., 2010; Dickson et al. 2007. Bates et al., 2001
Whole cruise CRM values varied by ± 5.04 µmol kg-1

Alkalinity:
Alkalinity was measured by an open cell, high precision potentiometric titration on a VINDTA instrument with a 250 mL sample. CRM Scale: Batch 119 (2014.78 ± 0.79 µmol kg-1). Whole cruise CRM values varied by ± 5.04 µmol kg-1. Method References: Mathis et al., 2010; Dickson et al. 2007. Bates et al., 2001

Instruments

CTD Sea-Bird SBE 911plus

Supplied Name: CTD SBE 911plus

Supplied Description:

Sea Bird 911 CTD

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

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.
