OOI-Irminger 2023
Completed
Operating area: Irminger Sea SE of Greenland 60N, 39W
Route: Reykjavik - Iceland → Woods Hole (Massachusetts) - United States
Woods Hole Oceanographic Institution
Project aboard
To carry out the recovery and redeployment of the NSF Ocean Observatories Initiative (OOI) Irminger Sea Array, servicing four moorings and up to five gliders in an area southeast of Greenland (38-41W, 58-61N). The platforms will carry multidisciplinary instrumentation and provide the capability for real time communication of data and control of sampling. A surface mooring will instrument the sea surface and upper ocean, capturing the surface forcing and upper ocean variability. A profiling mooring will measure through the water column. Two additional taut subsurface moorings and the gliders will complete the capabilities to obtain vertical profiles and sample the mesoscale (10s to 100 km) variability at the site. Shipboard data will be obtained to assess the performance of the instrumentation.
