The Mackenzie Shelf in the southeastern Beaufort Sea is a region that has experienced large changes in the past several decades as warming, sea-ice loss, and increased river discharge have altered carbon cycling. Upwelling and downwelling events are common on the shelf, caused by strong,...

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
Download2019-01-01
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,...

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...

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...

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...

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...

Simulated impacts of relative climate change and river discharge regulation on sea ice and oceanographic conditions in the Hudson Bay Complex

Lukovich, Jennifer V., Jafarikhasragh, Shabnam, Myers, Paul G., Ridenour, Natasha A., de la Guardia, Laura Castro, Hu, Xianmin, Grivault, Nathan, Marson, Juliana, Pennelly, Clark, Stroeve, Julienne C., Sydor, Kevin, Wong, Karen, Stadnyk, T. A., Barber, D. G.
In this analysis, we examine relative contributions from climate change and river discharge regulation to changes in marine conditions in the Hudson Bay Complex using a subset of five atmospheric forcing scenarios from the Coupled Model Intercomparison Project Phase 5 (CMIP5), river discharge...

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...

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...
