Use caution in a # merging of data from different sources. # depth_tow = depth of plankton tow, units = meters # aliquot = aliquot value is the reciprocal (1/value)of the fraction of the # sample volume employed for the CHN measurement. # vol_filt = volume of water filtered by the net, units= m^3 # sizefrac = size fraction of organisms analyzed, units = mm # C = Carbon, units = ug # N = Nitrogem, units = ug # # Note: Biomass values are the means of two pseudoreplicates (subsamples # from one tow) # C_mass = Carbon biomass, units = mg/m^3 # N_mass = Nitrogen biomass, units = mg/m^3 # C_to_N = Carbon to Nitrogen ratio, units = ratio is of biomass # ========================= year event sta cast ------------------------- 1989 05181743 25 13 1989 05182340 25 15 1989 05201402 27 08 1989 05231315 30 09 1989 05240036 31 01 1989 05251345 32 10 1989 05272330 34 13 1989 05291300 36 09 1989 05292315 36 13 1989 05311300 38 09 1989 05312300 38 12
