Science Objectives

Five days will be devoted to the recovery and re-deployment of 4 (NSF) Overturning of Subpolar North Atlantic (OSNAP) moorings and, if time, complete a CTD array near the mooring sites, locations TBD. The OSNAP moorings monitor the velocity, temperature and salinity of the boundary current between ~37.8-41.1 W, 59.6-59.9N.  The OSNAP moorings include 1 tall mooring with its uppermost instrument at 42 m, and 3 shorter moorings with their uppermost instruments between 950 and 1455 m. Approximately 60 microcats (30 to be deployed, and 30 recovered) will be calibrated by means of 'caldips' (detailed below).  CTD/Rosette casts will be made at all mooring locations, and will follow the OOI protocal.

Science Activities

OSNAP Science Activities, not necessarily in time-order, recovery will occur before deployment:

1. For the 30 microcat instruments to be deployed, perform 3 calibration dips:

  1. Place 10 microcats on the rosette frame struts, lower over the side. 
  2. Take concurrent CTD and microcat measurements, 12 different depths, ranging through the water column, and to 3000 meters depth.  Wait 10 minutes at each bottle stop. 

2. In-water test of 8 acoustic releases:

  1. ~2 releases will be attached to rosette during ~4 CTD casts.
  2. Test release by sending release command when release is below 2000 m depth.

3. For each of the 4 moorings to be deployed:

  1.  
    1. Perform a CTD/Rosette cast.
    2. Deploy the mooring.
    3. Perform an anchor survey for the deployed mooring.

4. For each of the 4 moorings to be recovered:

  1.  
    1. Signal to acoustic release, send release command.
    2. Recover mooring.

5. For the 30 microcat instruments to be recovered, perform 3 calibration dips:

  1. Place ~10 microcats on the rosette frame struts, lower over the side. 
  2. Take concurrent CTD and microcat measurements, 12 different depths, ranging through the water column, and to 3000 meters depth.  Wait 10 minutes at each bottle stop.

5. Complete CTD section by performing CTD/Rosette cast al locations TBD, but near the OOI work area, as time permits.
