Dataset description

SEEDS 2001 Pre Fertilization (PF) CTD profile data

Acquisition description

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
