Lukovich, Jennifer V., Tefs, Andrew, Jafarikhasragh, Shabnam, Pennelly, Clark, Myers, Paul G., Stadnyk, Tricia A., Sydor, Kevin, Wong, Karen, Vieira, Michael, Landry, David, Stoeve, Julienne C., Barber, D. G.
In this article, we examine atmospheric and river discharge conditions within the Hudson Bay Complex for the BaySys 2016-2018 field program time frame. Investigated in particular is a subset of European Centre for Medium-Range Weather Forecasts (ECMWF) Re-Analysis - Interim (ERA-Interim)...

Lukovich, Jennifer V., Jafarikhasragh, Shabnam, Tefs, A., Myers, Paul G., Sydor, K., Wong, K., Stroeve, Julienne C., Stadnyk, T. A., Babb, D., Barber, D. G.
In this paper, we examine sea surface temperatures (SSTs) and sea ice conditions in the Hudson Bay Complex as a baseline evaluation for the BaySys 2016-2018 field program time frame. Investigated in particular are spatiotemporal patterns in SST and sea ice state and dynamics, with rankings of the...

Pulses of ocean primary productivity during the fall season are frequent in the mid-latitudes when ocean cooling and wind-driven turbulence erode the surface stratification and allow the injection of nutrients into the euphotic zone. This phenomenon is often referred to as a phytoplankton fall...

Hudson Bay of northern Canada receives upward of 700 km3 of river discharge annually. Cyclonic water circulation in Hudson Bay transports this massive volume of riverine water along the coast toward Hudson Strait and into the Labrador Sea. However, synoptic, seasonal and interannual variability...

Impact of extended NAO buoyancy forcing on the subpolar North Atlantic and climate variability over the last millenium
Download2007
We examine the impact of forcing a regional eddy-permitting ocean model of the subpolar North Atlantic with anomalous buoyancy fluxes corresponding to extended extreme states of the North Atlantic Oscillation (NAO). We find a weakened (enhanced) Meridional Overturning Circulation (MOC) in our low...

Deep convection in the Labrador Sea is an important component of the global ocean ventilation. The associated loss of heat to the atmosphere from the interior of the sea is thought to be mostly supplied by mesoscale eddies, generated either remotely or as a result of convection itself—processes...

Sensitivity of the subpolar North Atlantic to Last Glacial Maximum surface forcing and sea ice distribution in an eddy-permitting regional ocean model
Download2006
Myers, Paul G., Bush, Andrew B. G., Yang, Duo
The impact of paleoatmospheric forcing and sea ice distribution on the circulation of the subpolar North Atlantic is examined in a regional eddy-permitting ocean model. We focus on water mass formation and the pathway of the North Atlantic Current. Paleofluxes are obtained from a coupled...

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...

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...

Wind-forced depth-dependent currents over the eastern Beaufort Sea continental slope: Implications for Pacific water transport

Dmitrenko, Igor A., Kirillov, Sergei A., Myers, Paul G., Forest, Alexandre, Tremblay, Bruno, Lukovich, Jennifer V., Gratton, Yves, Rysgaard, Soren, Barber, David G.
Pacific water contributes significantly to the Arctic Ocean freshwater budget. Recent increases in Arctic freshwater flux, also affected by the Pacific-derived Arctic water, impact the Atlantic overturning circulation with implications for global climate. The interannual variability of the...
