Departure: Aug 5, 2015
Woods Hole, Ma on Jun 30, 2016
Arrival: Sep 1, 2015
Reyjkavik, Iceland on Jul 28, 2016
Operations Area
Southeast of Greenland
Lat/Lon: 59° 52.0′ N / 39° 30.0′ W
Depth Range: 2600 / 2800
Will the vessel be operating within 200 NM of a foreign country?	Yes, Iceland Greenland. Clearance applied for.
Are visas or special travel documents required?	no
Science Objectives
To carry out the recovery and redeployment of the NSF Ocean Observatories Initiative (OOI) Irminger Sea Array for 2016, 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; 3)  Recover the four moorings deployed in 2015; 4) Deploy four gliders in support of horizontal and vertical sampling in and around the array; 5) Recover one glider deployed in 2015; and 6) Carry out shipboard sampling in support of calibration and validation of the deployed sensors on the moorings and gliders and to add to knowledge of the site.
