Methods & Sampling

Seawater samples were collected from discrete depths during CTD casts using Niskin bottles attached to the CTD rosette. Sub-samples (100mL) of seawater were filtered onto GF/F filters and frozen at -20˚C for later analysis of chlorophyll-a and phaeopigment concentrations following the acidification technique described in the JGOFS protocols using a Turner 10AU fluorometer. Details of sampling and analytical procedures can be found in O’Loughlin et al. (2020).

Data Processing Description

BCO-DMO Processing:
- concatenated data from two separate cruise files into one dataset;
- added station latitude, longitude, depth, and transect name from the "ShimadaStations.xlsx" file;
- changed date format to YYYY-MM-DD;
- re-named fields.

Instruments

CTD Sea-Bird 911

Supplied Name:

Supplied Description:

Instrument Type

Generic Name: CTD Sea-Bird 911

Acronym: CTD SBE 911

Community Identifier: http://vocab.nerc.ac.uk/collection/L22/current/TOOL0035/

Generic Description:

The Sea-Bird SBE 911 is a type of CTD instrument package. The SBE 911 includes the SBE 9 Underwater Unit and the SBE 11 Deck Unit (for real-time readout using conductive wire) for deployment from a vessel. The combination of the SBE 9 and SBE 11 is called a SBE 911. The SBE 9 uses Sea-Bird's standard modular temperature and conductivity sensors (SBE 3 and SBE 4). The SBE 9 CTD can be configured with 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 Name: Niskin bottles

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.

Turner Designs Fluorometer 10-AU

Supplied Name: Turner 10AU fluorometer

Supplied Description:

Instrument Type

Generic Name: Turner Designs Fluorometer 10-AU

Acronym: Turner Fluorometer 10-AU

Community Identifier: http://vocab.nerc.ac.uk/collection/L22/current/TOOL0393/

Generic Description:

The Turner Designs 10-AU Field Fluorometer is used to measure Chlorophyll fluorescence. The 10AU Fluorometer can be set up for continuous-flow monitoring or discrete sample analyses. A variety of compounds can be measured using application-specific optical filters available from the manufacturer. (read more from Turner Designs, turnerdesigns.com, Sunnyvale, CA, USA)
