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...

Separating the influence of projected changes in air temperature and wind on patterns of sea level change and ocean heat content
Download2015
Saenko, Oleg A., Myers, Paul G., Gregory, Jonathan M., Yang, Duo, Spence, Paul
We present ocean model sensitivity experiments aimed at separating the influence of the projected changes in the “thermal” (near-surface air temperature) and “wind” (near-surface winds) forcing on the patterns of sea level and ocean heat content. In the North Atlantic, the distribution of sea...

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...

Potential positive feedback between Greenland ice sheet melt and Baffin Bay heat content on the west Greenland shelf
Download2015
Hu, Xianmin, Myers, Paul G., de la Guardia, Laura C.
Greenland ice sheet meltwater runoff has been increasing in recent decades, especially in the southwest and the northeast. To determine the impact of this accelerating meltwater flux on Baffin Bay, we examine eight numerical experiments using an ocean-sea ice model: Nucleus for European Modelling...

Kulan, Nilgun, Ribergaard, Mads H., Myers, Paul G.
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...

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°,...

Sensitivity of Labrador Sea Water Formation to Changes in Model Resolution, Atmospheric Forcing, and Freshwater Input.

Garcia-Quintana, Yarisbel, Courtois, Peggy, Hu, Xianmin, Pennelly, Clark, Kieke, Dagmar, Myers, Paul G.
Labrador Sea Water (LSW) is one of the main contributors to the lower limb of the Atlantic Meridional Overturning Circulation. In this study, we explore the sensitivity of LSW formation to model resolution, Greenland melt, absence of high-frequency atmospheric phenomena, and changes in...

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...

Extreme High Greenland Blocking Index Leads to the Reversal of Davis and Nares Strait Net Transport Toward the Arctic Ocean
Download2021-01-01
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...

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...
