Oceanographic data and information collected during the EX1708 Musicians Seamounts (ROV & Mapping) expedition on NOAA Ship OKEANOS EXPLORER in the Pacific Ocean from 2017-09-06 to 2017-09-30 (NCEI Accession 0170178)

This dataset contains oceanographic data collected in and around Hawaii, the US EEE, and in the High Seas around the Musicians Seamounts. Operations for this cruise were conducted 24 hours/day and consisted of daily remotely operated vehicle (ROV), overnight mapping, and full shore-based participation via telepresence. Operations included the use of the ship’s deep-water mapping system, XBT and CTD casts in support of multibeam sonar mapping operations, OER’s two-body ROV Deep Discoverer and Seirios, and the ship’s high-bandwidth satellite connection for continuous real-time ship-to-shore communications. Data acquisition from shipboard sensors includes navigation data, meteorological data (wind, air temperature, relative humidity, barometric pressure), and oceanographic data (thermosalinograph, sound velocity probe, bathythermograph). Operations also included the use of the ship’s Acoustic Doppler Current Profilers (ADCP).
