Science objectives

This research is part of the Overturning in the Subpolar North Atlantic Program (OSNAP), an effort to determine the strength of the meridional overturning circulation and associated heat and freshwater fluxes in the subpolar North Atlantic. It is a collaborative program with scientists from several nations, including the U.K., the Netherlands, Germany, France, Canada and China. Scientists from the U.S., the U.K., and China will participate in this cruise.


The specific objectives of this cruise are as follows:


1.  To deploy 25 current meter and sound source moorings in the southern Labrador Sea and southwest Irminger Sea.

2.  To conduct CTD/LADCP transects in combination with the vessel-mounted ADCP.

3.  To launch acoustically tracked RAFOS floats at a number of sites near the mooring line.

Science Activities

1.  To recover and deploy 25 current meter and sound source moorings in the southern Labrador Sea and southwest Irminger Sea.

2.  To conduct CTD/LADCP transects in combination with the vessel-mounted ADCP along the osnap line.

3.  To launch acoustically tracked RAFOS floats at a number of sites near the mooring line

4. Deploy sound source arrays for Dr. Amy Bower (WHOI)
