Dense water formation on the Icelandic shelf and its contribution to the North Icelandic Jet
Download2021-01-01
Garcia-Quintana, Yarisbel, Grivault, Nathan, Hu, Xianmin, Myers, Paul G.
The North Icelandic Jet (NIJ) is the densest component of the Denmark Strait Overflow Water, feeding the abyssal limb of the Atlantic Meridional Overturning Circulation. Here, by using observational and numerical model data, we explore the formation of overflow water on the Icelandic shelf, the...

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...

Pacific Water Pathway in the Arctic Ocean and Beaufort Gyre in Two Simulations With Different Horizontal Resolutions
Download2019-01-01
Hu, Xianmin, Myers, Paul G., Lu, Youyu
A set of numerical simulations (with horizontal resolutions of 1/4 degrees and 1/12 degrees ) is conducted to study the Pacific Water pathway in the Arctic Ocean and the freshwater content in Beaufort Gyre. Passive tracer tags the Pacific Water entering through Bering Strait into the Arctic Ocean...

Cascading of dense water from the shelf to deeper layers of the adjacent ocean basin has been observed in several locations around the world. The West Greenland Shelf (WGS), however, is a region where this process has never been documented. In this study, we use a numerical model with a 1/48...

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°,...

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...

Extreme High Greenland Blocking Index Leads to the Reversal of Davis and Nares Strait Net Transport Toward the Arctic Ocean

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...

Greenland freshwater pathways in the sub-Arctic seas from model experiments with passive tracers

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...

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...
