The Global Station Papa Array is a set of three moorings. With a distance between moorings approximately ten times that of the water depth, the array is able to collect data on the mesoscale variability. Unlike the design of the Global Irminger Sea Array, the Global Station Papa array does not have an OOI Surface Mooring.
The Irminger Sea is a marginal sea of the North Atlantic Ocean. It is bordered to the west by southern Greenland , to the north by Iceland and the Denmark Strait , to the east by the Reykjanes Ridge (a northern part of the Mid-Atlantic Ridge ), and to the south by open waters of the North Atlantic.
Both barotropic and baroclinic instabilities generate vorticity leading to eddies called Irminger Rings. Associated with the formation of IRs is an increase in Eddy Kinetic Energy (EKE). [3] IRs are not the only type of eddy spawned around the Labrador Sea. Convective events in the interior Labrador sea create steep density gradients.
The 3000-float array was achieved in November 2007 and was global. The Argo Steering Team met for the first time in 1999 in Maryland (USA) and outlined the principles of global data sharing. The Argo Steering Team made a 10-year report to OceanObs-2009 [ 5 ] and received suggestions on how the array might be improved.
The Global Drifter Program (GDP) (formerly known as the Surface Velocity Program (SVP)) was conceived by Prof. Peter Niiler, with the objective of collecting measurements of surface ocean currents, sea surface temperature and sea-level atmospheric pressure [1] using drifters.
The Irminger Current is a north Atlantic ocean current setting westward off the southwest coast of Iceland. It is composed of relatively warm and saline waters from the eastern North Atlantic that are fed by the North Atlantic Drift .
Both the DSOW and ISOW flow around the Irminger Basin and Labrador Sea in a deep boundary current. Leaving the Greenland Sea with 2.5 Sv, its flow increases to 10 Sv south of Greenland. It is cold and relatively fresh, flowing below 3500 m in the DWBC and spreading inward the deep Atlantic basins.
Some climate models indicate that the deep convection in Labrador-Irminger Seas could collapse under certain global warming scenarios, which would then collapse the entire circulation in the North subpolar gyre. It is considered unlikely to recover even if the temperature is returned to a lower level, making it an example of a climate tipping ...
