Oceanographic data collected during the EX1404L2 (Our Deepwater Backyard: Exploring the Atlantic Canyons and Seamounts) expedition on NOAA Ship OKEANOS EXPLORER in the North Atlantic Ocean from 2014-09-04 to 2014-09-10 (NCEI Accession 0121585)

Published by NOAA National Centers for Environmental Information | National Oceanic and Atmospheric Administration, Department of Commerce | Catalog Last Checked: August 03, 2026 at 02:33 AM | Dataset Last Updated: December 22, 2017 at 12:00 AM
This dataset contains oceanographic data collected on little or unknown areas of the continental slope between Rhode Island and Chesapeake Bay. The major driving objective during these dives was to conduct engineering trials of the ROV and focused outreach events. Dives in the area of Lindenkohl canyons were devoted to ROV engineering trials, dives in the area of Washington Canyon were focused on exploration, and dives at the head of Norfolk Canyon and the mid-Atlantic gas seep site focused on outreach operations. ROV dives were conducted mostly during the day, while CTD casts and acoustic mapping occurred when the ROV was on deck. Data acquisition from shipboard sensors includes navigation data, meteorological data (wind, air temperature, relative humidity, barometric pressure), and oceanographic data (thermosalinograph, remote temperature probe, sound velocity probe, bathythermograph).
