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 17 current meter moorings in the southeast Labrador Sea and southwest Irminger Sea.
2. To conduct a hydrographic/velocity survey in the vicinity of Cape Farewell.


Science Activities

1. We will attempt to recover and re-deploy 17 moorings. There are two types of moorings: tall oceanographic moorings (9); shelf-tripods (8). Since the time at the study is reduced (due to the COVID-19 situation), it is likely that we won't be able to service all of the moorings.

2. We will occupy CTD stations at all of the mooring sites, and also occupy some additional sections as time permits.

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