Zooplankton data: taxon-specific, fine-scale day and night distribution of mesozooplankton, with emphasis on gelatinous zooplankton taxa, in the Mississippi Bight collected aboard the R/V Point Sur, PTS03, from 2016-07-27 to 2016-07-28

This dataset contains Taxon-specific, fine-scale day and night distribution of mesozooplankton, with emphasis on gelatinous zooplankton taxa, in the Mississippi Bight collected aboard the R/V Point Sur, PTS03, from 2016-07-27 to 2016-07-28. As part of the CONCORDE field sampling campaign, an in-situ imaging system (ISIIS) was used to sample along one meridional transects spanning approximately 10 km. This dataset examines the western-most corridor for abundances of different mesozooplankton taxa, with emphasis on gelatinous zooplankton, during day and night in summer 2016. Three passes were conducted during the day and at night on the transect. Particles above a 2000-pixel size threshold (~3.3 mm equivalent spherical diameter) were automatically extracted and manually identified with the highest taxonomic resolution possible (in many cases, to genus). The ISIIS collected images of plankton along with high-resolution physical oceanographic data, which were merged using the nearest time stamp. The goal of the study was to describe the distribution of different plankton groups during the day and at night, with the goal of understanding vertical diel movements and potential oil exposure rates for different groups inhabiting the shelf ecosystem. The dataset contains the date, latitudes and longitudes of the sampling locations.
