 Parameter           Description                                  Units

 event               event number from event log
 sta                 station number from event log
 cast                cast number from event log
 cast_type           CTD = CTD rosette
                     TM = Trace Metal rosette
 depth_n             nominal sample depth                         meters
 size_frac           size fraction code                           dimensionless
                       200 = <200 micron seawater size fraction
                       wsw = whole seawater size fraction
 seawater            seawater dilution code                       dimensionless
                       1.2 = <1.2 micron seawater for dilutions
                       0.2 = <0.2 micron seawater for dilutions
 flag_y              yeast addition code                          dimensionless
                       0 = no yeast extract addition
                       1 = 1 milligram per liter yeast extract
                         addition (final concentration)
                      10 = 10 milligram per liter yeast extract
                         addition (final concentration)
 microzoo_graze      microzooplankton grazing on phytoplankton    per day
 flag_g              zero = slope not significantly different
                       from zero at the 0.05 level
 phyto_growth_net    net phytoplankton growth rate                per day
