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 04250957 10 04 1989 04252337 10 10 1989 04261045 11 04 1989 04262350 11 10 1989 04280947 13 03 1989 04282251 13 11 1989 04300923 15 06 1989 05022215 17 10 1989 05031037 18 05 1989 05040923 19 3A 1989 05042248 19 08 1989 05061323 21 04 1989 05070056 22 00
