Description

CTD profile data using the GEOTRACES Clean Carousel sampling system (GTC), GEOTRACES-Arctic cruise HLY1502.
GTC CTD BOTTLE: version 20160609ODU

Data 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
- reformatted time as HHMM

Instruments

CTD Sea-Bird SBE 911plus

Supplied Name:

Supplied Description:

The system included a Dynacon winch with 7300 m of Vectran cable with conductors, clean lab, and Seabird carousel/CTD with 24 12L GO-FLO bottles (and 14 spares), GO-FLO bottles.

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
