EK60 Water Column Sonar Data Collected During GU1806

1. Deploy various tags on GoMex whales 2. Photo and video documentation of GoMex whales 3. Recovery of short duration tags (camera and acoustic tags) 4. Collect tissue samples (biopsies) of GoMex whales from R3. 5. Deploy sonobuoys to collect recordings of the sounds produced by GoMex whales and of anthropogenic sounds 6. Periodic collection of oceanographic and environmental data including scientific echosounders (EK80) and acoustic Doppler current profiler (ADCP) data to quantify acoustic backscatter due to small fish and zooplankton 7. AdHoc collection of vertical profiles of hydrographic parameters (e.g., temperature, salinity, oxygen concentration) via CTD and Expendable Bathythermographs (XBTs) 8. Deploy and recover autonomous camera and acoustic recording buoys at select locations 9. Service HARP buoys located in the northeastern quadrant of the Gulf of Mexico
