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.

The specific objectives of this cruise are as follows:

1. To service 18 current meter and sound source moorings in the southeast Labrador Sea and southwest Irminger Sea.
2. To conduct a hydrographic/velocity survey in the vicinity of Cape Farewell and in Denmark Strait.


Science Activities

1. We will recover 18 moorings and deploy 17 moorings. There are three types of moorings: tall oceanographic moorings (9); shelf-tripods (8); sound source mooring (1).

2. We will occupy CTD/LADCP/Microstructure stations at all of the mooring sites, and also carry out a CTD/LADCP/Microstructure survey.

3. We will collect underway data throughout the cruise (vessel-mounted ADCP, Knudsen, met sensors).
