  "description": "Holoplankton abundance and carbon biomass by 33 higher taxa (copepods to family, plus amphipods, chaetognaths, salps, pyrosomes, pteropods, ostracods, foraminifera, radiolaria and more) from CalCOFI net tows, 1951-2021, enumerated by microscopy (Ohman Lab / SIO Pelagic Invertebrate Collection). One row per (sample, taxon, measurement_type); unpooled tows are station-resolved, pooled samples are per-cruise regional composites. Raw (uncorrected) abundance per 1000 m3 and per m2, plus biomass mg C/m2.\n",
