From May 14-27, 2021, NOAA Ocean Exploration will lead the 2021 Technology Demonstration on NOAA Ship Okeanos Explorer from Cape Canaveral, Florida, to Norfolk, Virginia. The expedition provides an opportunity to test several technologies that will allow the ocean exploration community to explore deeper, farther, and more comprehensively than previously possible. Expeditions like this are vital for the advancement of ocean exploration technologies that will benefit partners and the broader field of ocean exploration alike in our collective mission to explore, map, and understand the vast ocean realm. During the 2021 Technology Demonstration, 24-hour-a-day operations will focus on field engineering trials of WHOI’s new Orpheus class of autonomous underwater vehicles (AUVs), piloting NOAA Ocean Exploration’s environmental DNA (eDNA) sampling protocols, regular CTD rosette casts, and acoustic mapping of the seafloor and water column with the new EM 304 multibeam and deepwater sonar suite.
