This dataset contains oceanographic data collected from NOAA Ship OKEANOS EXPLORER in the North Pacific Ocean from 2023-04-13 to 2023-04-27. Data acquisition from shipboard sensors includes navigational data, METOC data (altimetry, conductivity, depth, dew point, fluorescence, oxygen, pressure, relative humidity, relative wind speed, salinity, sound speed, sound velocity, temperature, true wind, turbidity, water temperature, wind, wind direction, wind speed), vehicle data (ROV time to surface, traction winch data, line rate data), Profile Data (ASVP, CTD, and XBT), event logs, images, ROV ancillary data, ADCP data, and sample specimen data.
