2023 Shakedown + EXPRESS West Coast Exploration

2023 Shakedown + EXPRESS West Coast Exploration (EX2301);EX2301

From April 13-27, 2023 (Portland, Oregon, to Seattle, Washington), NOAA Ocean Exploration conducted the 2023 Shakedown + EXPRESS West Coast Exploration expedition (EX2301), a remotely operated vehicle (ROV) and Mapping expedition to shakedown the ROV, video, telepresence, seafloor mapping, and sampling operations aboard NOAA Ship Okeanos Explorer, as well as explore deep waters off the west coast of the United States. The ROV engineers tested and calibrated ROVs Deep Discoverer and Seirios motor controllers, auto position software, lighting systems, hydraulic systems, stills camera, high-definition ancillary ROV cameras, and sector-scanning sonar. Shakedown and readiness operations for the EM 304 MK II multibeam sonar system included a GNSS Azimuth Measurement Subsystem calibration, two patch tests, and a speed-noise test. Operations during this 15-day expedition included nine successful ROV dives, which were conducted in water depths ranging from 555 m to 3960 m for approximately 45:34 hours of bottom time and resulted in the collection of 92 samples. EX2301 also mapped 12,298 sq. km of seafloor (12,263 in the U.S. Exclusive Economic Zone). Data associated with this expedition have been archived and are publicly available through the NOAA archives.

Purpose	This expeditions operations were primarily focused on the shakedown and operational readiness of ROV and mapping operations aboard Okeanos Explorer for the 2023 field season, as well as collect critical baseline information and improve knowledge about unexplored and poorly understood deepwater areas off the west coast of California, Oregon, and Washington.
Use Limitations	otherRestrictions Access Contraints: If data contain the location of a cultural resource determined to be historically significant is revealed, Section 304 of the National Historic Preservation Act provides that the head of a Federal agency or other public official can withhold from public disclosure, information about the location, character, or ownership of a historic property when disclosure may cause a significant invasion of privacy; risk harm to the historic property; or impede the use of a traditional religious site by practitioners. Data collected by the EX or through the NOAA Ocean Exploration's competitive grants program and derivative data products that contain location information on historically significant properties will be archived in a location where it can be withheld from public disclosure.
