CarbonBridge August 2014: Zooplankton abundance, biovolume and size structure along transect D crossing the Fram Strait
Continuous data on zooplankton abundance and biovolume were collected in concert with data on the biophysical environment along a transect crossing the Atlantic Water inflow into the Arctic Ocean, in August 2014. The data were sampled by a Laser Optical Plankton Counter (LOPC; ODIM-Brooke Ocean Roll...
