40 distinct species

Across the time series Thysanoessa macrura is the most frequently occurring species

Methods

Zooplankton net tows were conducted at Palmer LTER grid stations. Tows were double oblique with a 2x2-m square mouth (700-um stretch mesh) Metro net to 120 m. Abundance (#/1000 m3) and biomass (i.e.. biovolume. mL/1000 m3) were determined for dominant macrozooplankton taxa. Data includes tow location. time. depth. and volume of water filtered by the net. Samples were preserved in 4% buffered formaldehyde. A blank abundance or biovolume value means that the sample was not analyzed for that taxonomic group; a value of -1 means that the taxonomic group was present but not quantified. Unit of abundance = AggregatedCount, Unit of biomass = Biovolume
