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...

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...

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...

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...

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...

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...

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,...

CSIB v1 (Canadian Sea-ice Biogeochemistry): a sea-ice biogeochemical model for the NEMO community ocean modelling framework

Hayashida, Haskase, Christian, James R., Holdsworth, Amber M., Hu, Xianmin, Monahan, Adam H., Mortenson, Eric, Myers, Paul G., Riche, Olivier G. J., Sou, Tessa, Steiner, Nadja S.
Process-based numerical models are a useful tool for studying marine ecosystems and associated biogeochemical processes in ice-covered regions where observations are scarce. To this end, CSIB v1 (Canadian Sea-ice Biogeochemistry version 1), a new sea-ice biogeochemical model, has been developed...

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...
