Science objectives

To carry out the recovery and redeployment of the NSF Ocean Observatories Initiative (OOI) Irminger Sea Array, servicing four moorings and up to four gliders.  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 mesocale (10s to 100 km) variability at the site.

Science Activities

The following activities are planned: 
1) Validate the bathymetry of the site to check the planned positions for the four moorings of the second deployment; 
2)  Deploy the four new moorings (1 surface & 3 subsurface)
3)  Recover the four moorings deployed in 2016
4) Deploy up to four gliders in support of horizontal and vertical sampling in and around the array 5) Recover glider deployed in 2016
6) Carry out shipboard sampling in support of calibration and validation of the deployed sensors on the moorings and gliders and to add to our knowledge of the site.
