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.

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)

From August 15- September 2, 2021, NOAA Ocean Exploration conducted mapping operations on the Blake Plateau within U.S. waters, aiding in closing the gaps within this region. This cruise consisted of a strategic transit from Newport, Rhode Island to the primary working grounds off of the U.S Southeast, aimed at collecting data over previously mapped and potentially new seeps along the edge of the continental shelf. EX-21-05 collected 13,054 square kilometers of bathymetry and associated water column data, 12,989 square kilometers of which were within the U.S. Exclusive Economic Zone and Territorial Sea deeper than 200 m. The cruise concluded in Port Canaveral, FL on September 2, 2021. The exploratory mapping operations conducted during this cruise will provide initial characterization of the region, as well as data to support further exploration with remotely operated vehicles planned for EX-21-07.
