BCO-DMO Processing Notes
- Generated from original files: "HLY1003_hy1, HLY1103_hy1, HLY1203_hy1.csv" contributed by Chase Stoudt
- UNOLS CruiseId added to each dataset
- Parameter names edited to conform to BCO-DMO naming convention found at Choosing Parameter Name
- Time reformatted from HH:MM to HHMM
- No PH_WS reported for HY1003 and HY1203
- No TCARBN reported for HY1103
- Parameters "PH_WS" and "PH_WS_FLAG_W" added HY1003 and HY1203 data with "nd" for values
- Parameters "TCARBN" and "TCARBN_FLAG_W" added to HY1103 with "nd" for values

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.
