Observing Mooring Deployment at Pioneer Array

Logan Johnsen on bridge

Logan Johnsen, chief mate on the research vessel Neil Armstrong, stood watch on the bridge recently during a mooring deployment at the Ocean Observatories Initiative (OOI) Pioneer Array. Instruments on the array record physical, chemical, and biological data from the seafloor to the surface and above around the clock, 365 days a year. Twice each year, a team from WHOI visits the Pioneer site, located about 100 miles south of Marthas Vineyard, to replace all of the moorings in the array and to deploy autonomous underwater vehicles that record data further afield.
