Description

CTD profile data using the GEOTRACES ODF system, GEOTRACES-Arctic cruise HLY1502.

Methods & Sampling

Dataset acquisition description

Note there were three separate rosette/CTD systems used on HLY1502. The GOSHIP rosette (coded GS in the event log) was also used for the Ra/Th/pigments profiles after station 10. There was a separate rosette that was loaded with 12 30-liter Niskins, but we only used that until station 10 (and once again at station 26). The GEOTRACES cruise report (PDF) mentions this, but does not provide detailed sensor information.

Data Processing Description

Dataset Processing Description

BCO-DMO Processing:
- added conventional header with dataset name; PI name; version date
- added cruise_id column plus information from headers: EXPOCODE, SECT_ID, STNNBR, CASTNO, GEOTRC_EVENTNO, DATE, TIME, LATITUDE, LONGITUDE, BTMDEPTH, INSTRUMENT_ID
- added column ISO_DateTime_UTC, calculated from Date and Time columns.
- 2022-12-15: made the CDOMF and CDOMF_FLAG_W columns public (were previously hidden)

Version History:
2017-05-22 (v1) - dataset made available from BCO-DMO; considered validated/final
2022-12-15 (v2) - CDOMF and CDOMF_FLAG_W made public.

Instruments

CTD Sea-Bird SBE 911plus

Supplied Name:

Supplied Description:

The system included Seabird carousel/CTD with 12-place 30L Niskin bottles (coded 30-ODF in event log) and a 36-place 10L Niskin bottles (coded Ra/Th/pigments in event log). The PAR calibration sheet is available (pdf)

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
