The CTD + 24 bottle sampling rosette was run using standard operating procedures. The bottles were fired on the up cast, 30 seconds after the unit was stopped.

Data Processing Description

Data were processed with provided config file (1377_27APR2019_McGreal.xmlcon). CTD data were binned by pressure and the bottle files extracted using SBEDataProcessing software.

BCO-DMO Processing:
- used awk script to re-format bottle files (moving avg and stdevs to columns);
- aggregated data from separate casts into one dataset;
- added lat and lon from file headers: NMEA Latitude, NMEA Longitude (converted to decimal degrees);
- added ISO date-time column.

Instruments

CTD Sea-Bird SBE 911plus

Supplied Name: Sea-Bird SBE 9 11+ V 5.2

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

Niskin bottle

Supplied Name:

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.

Parameters

Date and time formats are described in python strftime() syntax.
