Marson, Juliana M., Myers, Paul G., Hu, Xianmin, Petrie, Brian, Azetsu-Scott, Kumiko, Lee, Craig M.
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...

Dense water formation on the Icelandic shelf and its contribution to the North Icelandic Jet

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 oceanic heat available in Greenland’s troughs is dependent on the geographic location of the trough, the water origin, and how the water is impacted by local processes along the pathway to the trough. This study investigates the spatial pattern and quantity of the warm water (with a...

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...

We use an eddy-permitting, 1/12° regional configuration of the Nucleus for European Modelling of the Ocean (NEMO) model to examine water mass subduction rates in the Labrador Sea for the 2002–2013 period. An instantaneous kinematic subduction approach is implemented to calculate the subduction...

Labrador Sea Water formation rate and its impact on the local Meridional Overturning Circulation

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,...

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...

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...
