The Northeast U.S. Shelf Long-Term Ecological Research program (NES-LTER) is designed to improve our ability to predict how climate change will affect the dynamics of the shelf’s planktonic food webs and their ability to support the productivity of higher trophic levels. Ship-based field osbervations were conducted 4 times a year with multidisciplinary measurements of physical, biological, and chemical properties in the ocean.

During the project we characterized two open ocean eddies: one cyclonic and one anticyclonic in the waters south of Oʻahu, Hawaiʻi in the Central North Pacific Ocean. We conducted CTDs with water collection for nutrients, chlorophyll, and eDNA, we conducted net tows to quantify and describe the zooplankton and micronekton, and to collect genetic voucher specimens. Throughout the project we intermittently collecte EK80 and ADCP data. **Just a note: The ADCP data was not continuous on this cruise, as we had to toggle between collecting ADCP and EK80 data. So ADCP was collected during station operations, and EK80 while we transited between stations. The TS data was collected continuously.

Navy The Board of Inspection and Survey (INSURV)

During the cruise, watercolumn sonar data was collected using EK80 with single frequency transcievers at 38, 70, 120, and 200 kHz frequencies (7 degree circular beam angles). Instrument successfully calibrated on 06/09/2022 and data collected with updated settings. Note: sound speed is not updated accoring to CTD - should be updated before use Ancillary data: CTD casts, ADCP (continuous during survey), TSG (continuous during survey)

The Windows to the Deep 2021: Southeast U.S. ROV and Mapping expedition (EX-21-07) was a combined mapping and remotely operated vehicle (ROV) expedition to the Blake Plateau and Florida Straits that took place between October 26 and November 15, 2021. Operations during this 21-days at sea expedition included a combination of ROV dives in support of NOAA Ocean Exploration and its partner priorities. The primary focus of this expedition was the Blake Plateau, including its escarpment, off the coast of the Southeast U.S., but three dives were also conducted in the western and central Florida Straits due to weather conditions. Overall, 14 dives were completed, including two explorations of the water column, several dives to mound and ridgelike structures likely to be bioherms, two deeper dives to explore the steep Blake Escarpment, and one dive to document a lone sinkhole in the southeast region of the Blake Plateau. ROV dives were conducted from 300 m to 3650 meters water depth for a total of 47 hours of bottom time, and 15,800 square km were mapped using EM 304 multibeam sonar.
