   dataset:         Picophytoplankton cell counts
   dates:           July 18, 1995 to August 11, 1995
   location:        N: 22.5001  S: 9.9966  W: 57.2997  E: 68.7507
   project/cruise:  Arabian Sea/TTN-049 - Process Cruise 4 (Middle SW Monsoon)
   ship:            Thomas Thompson
 
   PI Note:
   Our data on picophytoplankton counts were obtained by flow cytometry
   of preserved samples (0.1% glutaraldehyde, stored in liquid nitrogen).
   Samples collected from CTD/rosette bottle casts, usually
   12 depths per station.

Notes on revised picophytoplankton data for TTN049, Process Cruise 4
 
Two important changes were made:
 
   1. Correction was made for a software flaw which resulted in
miscalculation of the analysis time and thus produced a 10%-15% error
in cell numbers.
 
   2. Cells observed in deep secondary chlorophyll maxima at the
sub-oxic zone and previously classified as picoeukaryotes were
reclassified as Prochlorophytes.
