Dataset description

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

Acquisition description

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.

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.

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
