Deployment-specific acquisition description

Sampling and Analytical Methodology:

pH:
pH was analyzed by a Spectrophotometric method using purified mCP at a temperature of 25C Total Scale. Accuracy Info: 0.001 in precision and 0.002 in accuracy. Method References: Xuewu Liu, Mark C. Patsavas, and Robert H. Byrne Purification and Characterization of meta-Cresol Purple for Spectrophotometric Seawater pH Measurements Environmental Science & Technology 2011 45 (11), 4862-4868

Alkalinity:
Alkalinity was measured by a one point spectrophotometric measurement with a 300 mL sample. Whole cruise CRM values varied by ± 1 µmol kg- Method References: Xuewu Liu, Robert H. Byrne*, Michael Lindemuth, Regina Easley, and Jeremy Mathis A rapid automated procedure for laboratory and shipboard spectrophotometric measurements of seawater alkalinity: continuously monitored single-step acid additions (In preparation to Marine Chemistry)

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.
