Oceanographic data collected during the EX1404L3 (Northeast Seamounts and Canyons) expedition on NOAA Ship OKEANOS EXPLORER in the North Atlantic Ocean from 2014-09-16 to 2014-10-17 (NCEI Accession 0123118)

This dataset contains oceanographic data collected along the continental slope submarine canyons, en route to and returning from the North Atlantic Seamount Chain. ROV operations were conducted on the seamounts both inside and outside the U.S. EEZ. Operations focused on areas of high potential for discovery and of interest to the management community. 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).
