October Expedition to Deploy and Recover Test Moorings in Prep for  Move to Mid-Atlantic Bight

A team of scientists and engineers will leave Woods Hole, MA aboard the R/V Armstrong on October 23, 2023 to conduct a variety of at-sea tests to continue preparations for the anticipated move of the Coastal Pioneer Array to the Mid-Atlantic Bight, off Cape Hatteras, NC. The team has a very busy agenda. First will be the deployment of a newly designed shallow water mooring off the coast of Martha's Vineyard, for easy access and recovery and to test its suitability in a shallow environment. From there, the team will head to the mid-Atlantic Bight to recover a mooring and two anchors that have been in place since spring 2023. Other activities will include a site survey, an ROV inspection of alternate locations, water and CTD sampling to ensure the new array is properly sited. The public comment period on the environmental assessment of the new location is open until October 30, 2023.

R/V Neil Armstrong

The R/V Neil Armstrong is a state-of-the-art oceangoing research vessel. The ship is 238 feet long, can sustain speeds of 10 knots, has a range of 11,500 nautical miles, and can remain at sea for up to 40 days. Named for the American hero whose “small step” provided humanity with a new perspective on our planet, this vessel carries on its namesake’s legacy of exploration.
