Greenland freshwater pathways in the sub-Arctic seas from model experiments with passive tracers
Download2016
Chassignet, Eric, Lee, Craig M., Bamber, Jonathan L., Curry, Beth, Dukhovskoy, Dmitry S., Timmermans, Mary-Louise, Platov, Gennady, Myers, Paul G., Proshutinsky, Andrey, Hu, Xianmin, Somavilla, Raquel
Accelerating since the early 1990s, the Greenland Ice Sheet mass loss exerts a significant impact on thermohaline processes in the sub-Arctic seas. Surplus freshwater discharge from Greenland since the 1990s, comparable in volume to the amount of freshwater present during the Great Salinity...

The LAB60 simulation is a coupled ocean sea-ice model (NEMO) that uses grid refinement to achieve high resolution (1/60 of a degree) within the Labrador Sea. This simulation starts in 2002 and will cover a period of over 10 years. This video shows our Greenland runoff passive tracer depth...

Pennelly, Clark, Myers, Paul G.
A numerical modeling sensitivity study is carried out within the Labrador Sea by varying the atmospheric conditions. From forcing NEMO simulations with five atmospheric products commonly used in ocean modeling (DFS5.2, ERA-Interim, CGRF, ERA5, and JRA55-do), we calculate the air–sea heat fluxes...

We examine the historical variability of Irminger Water (IW) along 3 sections across the West Greenland Current over 1950–2005. Significant variability in the salinity, size and position of the IW core are seen over time. Some of the saltiest and warmest IW ever recorded have been seen since 1995...

Labrador Sea Water formation rate and its impact on the local Meridional Overturning Circulation
Download2019-01-01
Feucher, Charlene, Garcia-Quintana, Yarisbel, Yashayev, Igor, Hu, Xianmin, Myers, Paul G.
This paper investigates the link between the Labrador Sea Water (LSW) formation rate and the strength of the Atlantic Meridional Overturning Circulation within the Labrador Sea. LSW is formed in the Labrador Sea through deep wintertime ocean convection and is then carried out of the basin by,...

Gillard, Laura C., Hu, Xianmin, Myers, Paul G., Bamber, Jonathan L.
The Greenland ice sheet (GrIS) stores the largest amount of freshwater in the Northern Hemisphere and has been recently losing mass at an increasing rate. An eddy-permitting ocean general circulation model is forced with realistic estimates of freshwater flux from the GrIS. Two approaches are...

The Labrador Sea experiences deep convection, a process where the oceans’ surface cools to the point where it may become more dense than the water at depth, promoting sinking and vertical mixing. This mixing can exceed 2000m in depth, producing a large volume of deep water, a crucial component in...
