CTD-ODF profiles from GEOTRACES-Arctic Section cruise HLY1502, August to October 2015 (U.S. GEOTRACES Arctic project)

Expand/Collapse All

Description

CTD profile data using the GEOTRACES ODF system, GEOTRACES-Arctic cruise HLY1502.
ODF CTD profiles: version 20160310CCHSIOSEE

Acquisition Description

Note that 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 12x 30L Niskins, but we only used that until station 10 (and once again at station 26). The GEOTRACES cruise report mentions this, but does not provide detailed sensor information.

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.

CTD Sea-Bird SBE 911plus

(more info)

Short Name: CTD SBE 911plus

Community Standard Description

Generic Description

The Sea-Bird SBE 911plus is a type of CTD instrument package for continuous measurement of conductivity, temperature and pressure. The SBE 911plus 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 9plus and SBE 11plus is called a SBE 911plus. The SBE 9plus uses Sea-Bird's standard modular temperature and conductivity sensors (SBE 3plus and SBE 4). The SBE 9plus 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

Dataset-specific 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)
