Description

SOIREE CTD at Bottle Trip Data
CTD Stations with pressure, temperature, salinity and oxygen values at bottle trips

Methods & Sampling

See SOIREE Preliminary Voyage Report
CTD data collection for SOIREE used NIWA's Seabird 911plus CTD and related
instrumentation - operated in its standard configuration, and according to standard procedures.

Data Processing Description

See SOIREE Preliminary Voyage Report
CTD data processing followed standard procedures.
These processes routinely result in pressure, temperature, salinity and
dissolved oxygen data that conform to WOCE Hydrographic Programme standards
(see WOCE HP Operations Manual WHP 91-1). with the measurements referenced
to (calibrated against) their respective international standards.

For SOIREE, the main exception was that there was no water-sample dissolved
oxygen data collected during the cruise. This meant that the dissolved O2
data could not be reliably calibrated to WOCE standards and that they are
only crudely indicative. It would be possible to somewhat further enhance
these dissolved O2 data by applying a calibration from a previous or
following cruise that used the same sensor.

provided on the Deep-Sea Research II 48 (2001) accompanying CD-Rom

BCO-DMO Edits
- parameter names modified to conform to BCO-DMO convention
- Station Number changed to station
- added 'T' to CTD Station number for compatibility with events in other spreadsheets
- date reformatted to YYYYMMDD
- time reformatted to HHMM
- lon/lat converted from degs min.decimal min to decimal degrees

Instruments

CTD Sea-Bird 911

Supplied Name: CTD Seabird 911

Supplied Description:

NIWA's Seabird 911plus CTD and related instrumentation

Instrument Type

Generic Name: CTD Sea-Bird 911

Acronym: CTD SBE 911

Community Identifier: http://vocab.nerc.ac.uk/collection/L22/current/TOOL0035/

Generic Description:

The Sea-Bird SBE 911 is a type of CTD instrument package. The SBE 911 includes the SBE 9 Underwater Unit and the SBE 11 Deck Unit (for real-time readout using conductive wire) for deployment from a vessel. The combination of the SBE 9 and SBE 11 is called a SBE 911. The SBE 9 uses Sea-Bird's standard modular temperature and conductivity sensors (SBE 3 and SBE 4). The SBE 9 CTD can be configured with auxiliary sensors to measure other parameters including dissolved oxygen, pH, turbidity, fluorescence, light (PAR), light transmission, etc.). More information from Sea-Bird Electronics.
