Oceanographic data collected during the Profiling Sensor to Map N2 Gas Production in OMZs (Hood Gas) 2017 expedition on NOAA Ship OKEANOS EXPLORER and R/V Robertson in the North Pacific Ocean and Hood Canal, Washington, from 2017-08-15 to 2017-11-11

Published by NOAA National Centers for Environmental Information | National Oceanic and Atmospheric Administration, Department of Commerce | Catalog Last Checked: August 03, 2026 at 08:17 AM | Dataset Last Updated: August 28, 2023 at 12:00 AM
This dataset contains meteorological data (wind, air temperature, relative humidity, barometric pressure), and oceanographic data (thermosalinograph, sound velocity probe, bathythermograph, CTD, GTD, processed Winkler titration data, dissolved gases and nutrient data, and digital camera imagery). Operations also included the use of the ship's Acoustic Doppler Current Profilers (ADCP). The goal of this project was to test new profiling GTD on the hydrowire, document the use of the sensor, and perform inter-calibrations with mass spectrometric measurements made on seawater samples (measurements made by UMass Dartmouth). The newly developed Gas Tension Device (GTD) for this project was successfully tested. The new GTD was used to 150 m depth on the ship's rosette CTD and step profiled throughout the water column. This dataset contains oceanographic data collected in the Hood Canal, Washington, and along the Clarion-Clipperton Fracture Zone and the transit track between Honolulu, Hawaii and Balboa, Panama.
