Abundance and biovolume of taxonomically-resolved phytoplankton and microzooplankton imaged continuously underway with an Imaging FlowCytobot along the NES-LTER Transect in winter 2018

These data represent the abundance and biovolume of
taxonomically-resolved phytoplankton and microzooplankton imaged
continuously underway along the NES-LTER Transect during cruise EN608
in winter 2018. Images were obtained with an Imaging FlowCytobot
(IFCB) sampling at approximately 20-min intervals from seawater
supplied from 5 meters water depth. Data are provided for the subset
of images during the cruise that were on the north-south transect
along longitude 70 53’ W. Sizes for individuals were determined
automatically by image processing, while identifications to
morphological categories were done manually. Data are provided by
taxon with names and machine-readable identifiers matched to the
lowest taxonomic level to the World Register of Marine Species. Two
data tables are provided: the level 1b for each occurrence and the
level 2 that summarizes the occurrences by taxon per sample.
Individual and sample identifiers are linked to images served by an
external repository. This data package provides 144,281
machine-readable occurrences for incorporation into the Ocean
Biogeographic Information System and the Global Ocean Observing System
Essential Ocean Variables Phytoplankton biomass and diversity and the
microplankton size class of Zooplankton biomass and diversity.
