It is not explicitly stated but it appears that at all stations
two CTD sampling rosette casts were made: clean and rms.

The clean rosette appears to have typically sampled the mixed layer(<50 m)

e.g. 5, 10, 20, 30, 50 m.

The rms rosette appears to have typically sampled the euphotic zone (<200 m)

e.g. 10, 20, 30, 40, 50, 80, 100, 150, 200 m.

NOTE: Temp is T068 scale

BCO-DMO Processing Notes
Generated from the original CTD data

BCO-DMO Edits
- Cruise event generated as YYYYMMDDHHMM
- Parameter names modified to conform to BCO-DMO convention
- Date converted to YYYYMMDD
- Time converted to HHMM
- Lat/Lon converted from degs, decimal minutes to decimal degrees

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.
