Pennelly, Clark, Hu, Xianmin, Myers, Paul G.
The amount of cross‐isobath freshwater exchange within the North Atlantic subpolar gyre is estimated from numerical modelling simulations. A regional configuration of the Nucleus for European Modelling of the Ocean model is used to carry out three simulations with horizontal resolutions of 1/4°,...

Marson, Juliana M., Gillard, Laura C., Myers, Paul G.
While Greenland discharge has been increasing in the last decades, its impact on the Meridional Overturning Circulation (MOC) is not clearly established. Because of that, the accuracy of this discharge representation in ocean models has not been a priority in large-scale circulation studies. Many...

Effect of a variable eddy transfer coefficient in an eddy-permitting model of the subpolar North Atlantic Ocean
Download2005
The effect of using a variable eddy transfer coefficient for the Gent–McWilliams (GM) parameterization in a (1/3)°-resolution ocean model of the subpolar North Atlantic Ocean is investigated. Results from four experiments with different implementations of this coefficient are compared among...

Myers, Paul G., de al Guardia, Laura Castro, Fu, Chuanshuai, Gillard, Laura C., Grivault, Nathan, Hu, Xianmin, Lee, Craig M., Moore, G. W. K., Pennelly, Clark, Ribergaard, Mads Hvid, Romanski, Joy
Baffin Bay exports Arctic Water to the North Atlantic while receiving northward flowing Atlantic Water. Warm Atlantic Water has impacted the retreat of tidewater glaciers draining the Greenland Ice Sheet. Periods of enhanced Atlantic Water transport into Baffin Bay have been observed, but the...

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 video shows the freshwater layer thickness (in meters), relative to a salinity of 34.8, from 2005 through the end of 2018. Higher...

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...
