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...

Gillard, Laura C., Hu, Xianmin, Myers, Paul G., Ribergaard, Mads Hvid, Lee, Craig M.
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...

Modeling dissolved and particulate 230Thin the Canada Basin: Implications for recent changes in particle flux and intermediate circulation

Yu, Xiaoxin, Allen, Susan E., Francois, Roger, Grenier, Melanie, Myers, Paul G., Hu, Xianmin
Global climate change has had large impacts on the Arctic region including rapid reductions in sea ice and rapid increases in surface air temperatures. Documenting the consequences of these changes in the Arctic Ocean is difficult, however, because accessibility limits observations in space and...

Water Mass Modification and Mixing Rates in a 1/12 degree Simulation of the Canadian Arctic Archipelago
Download2017-01-01
Hughes, Kenneth G., Klymak, Jody M., Hu, Xianmin, Myers, Paul G.
Strong spatial differences in diapycnal mixing across the Canadian Arctic Archipelago are diagnosed in a 1/128 basin-scale model. Changes in mass flux between water flowing into or out of several regions are analyzed using a volume-integrated advection–diffusion equation, and focus is given to...

Thermodynamic and dynamic ice thickness contributions in the Canadian Arctic Archipelago in NEMO-LIM2 numerical simulations
Download2018-01-01
Hu, Xianmin, Sun, Jingfan, Chan, Ting On, Myers, Paul G.
Sea ice thickness evolution within the Canadian Arctic Archipelago (CAA) is of great interest to science, as well as local communities and their economy. In this study, based on the NEMO numerical framework including the LIM2 sea ice module, simulations at both 1/4 and 1/12◦ horizontal resolution...

This thesis presents the numerical simulations related to freshwater processes within the Canadian Arctic Archipelago (CAA) using a coupled ocean and sea ice pan-Arctic model based on NEMO v3.1. In this study, two major routes for the export of Pacific water to the North Atlantic, via either Fram...

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...

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...

Ridenour, Natasha A., Hu, Xianmin, Sydor, Kevin, Myers, Paul G., Barber, David G.
The Hudson Bay Complex is the outlet for many Canadian rivers, receiving roughly 900 km3/year of river runoff. Historically, studies found a consistent cyclonic flow year-round in Hudson Bay, due to the geostrophic boundary current induced by river discharge and cyclonic wind forcing that was...

Using Vertically Integrated Ocean Fields to Characterize Greenland Icebergs’ Distribution and Lifetime
Download2018-01-01
Marson, Juliana M., Myers, Paul G., Hu, Xianmin, Le Sommer, Julien
Icebergs represent approximately half of Greenland’s yearly mass loss, having important implications for biological productivity, freshwater fluxes in the ocean, and navigation. This study applies an iceberg model that uses integrated ocean fields (from surface to iceberg keel) to simulate the...
