Dataset description
SOIREE Uncalibrated data from the ship's Data Acquisition System (DAS)
Underway data collected during SOIREE, sampled
at 5 minute intervals
The file also contains shipboard meteorological data.
The data are presented in a raw, uncalibrated form.
Missing data are marked by "nd".
Acquisition description
See SOIREE Preliminary Voyage Report
See comments in dataset description as well
A Chelsea instruments CTD/Fluorometer was mounted in a chamber that was supplied with
flow-through sea-water. From this instrument Temperature and Fluorescence were logged.
A Chelsea Instruments Fasttracka FRRF was used to record phytoplankton photosynthetic
competency (Fv/Fm).

BCO-DMO Processing Notes
Generated from original file das_5minute.txt provided on the
Deep-Sea Research II 48 (2001) accompanying CD-Rom
BCO-DMO Edits
- Parameter names modified to conform to BCO-DMO convention
- date reformatted to YYYYMMDD
- time reformatted to HHMM
- Note: Some times with 59 seconds truncated when fmtted for BCO-DCO
- lat/lon values padded o 4 decimal places
- other data values padded to 2 decimal places
- Note: Wind Speed and Wind Direction appear to have same values
