EK80 Water Column Sonar Data Collected During PC2305

Operational objectives were to: (1) collect biological data with 61-cm and 20-cm bongo nets; (2) collect ocean acidification water samples with rosette water sampler; (3) collect underway data using TSG, SCS, EK80, and ADCP; (4) collect marine mammal and seabird observations; (5) subsample pteropods from plankton nets collected at ocean acidification stations; (6) collect along track imagery of phytoplankton and ciliates using Imaging FlowCytobot unit; (7) conduct radiometry cast for photosynthetically available radation (PAR) measurements; (8) subsample plankton from plankton nets for use in plankton energy density estimates; (9) collect supplemental bongo sampoles in Wind Energy Areas in southern New England; (10) subsample plankton for carbon and nitrogen isotope analysis; (11) collect plankton samples with a 75-cm ring net; and (12) collect larval fish with a 90-cm bongo net for use in swim testing.
