Methods & Sampling

PF Station Header
PF00.HDR:* System UpLoad Time = Jul 05 2001 07:08:41

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 ITS-90 scale

Data Processing Description

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

Generic Name: CTD Sea-Bird SEACAT 19

Acronym: CTD SBE 19

Community Identifier: http://vocab.nerc.ac.uk/collection/L22/current/TOOL0042/

Generic Description:

The Sea-Bird SBE 19 SEACAT Recorder measures conductivity, temperature, and pressure (depth). The SEACAT is self-powered and self-contained and can be deployed in profiling or moored mode. The SBE 19 SEACAT was replaced in 2001 by the 19plus. more information from Sea-Bird Electronics
