Fall 2021
The Labrador Sea experiences deep convection, a process where the oceans’ surface cools to the point where it may become more dense than the water at depth, promoting sinking and vertical mixing. This mixing can exceed 2000m in depth, producing a large volume of deep water, a crucial component in...

Fall 2018
The Arctic and the North Atlantic Oceans are experiencing multiple stresses such as loss of sea ice, changing atmospheric patterns, increasing wind energy at the ocean surface and larger freshwater discharge to coastal regions. To address how the marine system may respond to these stresses I...

Spring 2012
This thesis presents a modified version of the Finite Element Ocean Model (FEOM) developed at Alfred Wegener Institute for Polar and Marine Research (AWI) for the North Atlantic Ocean. A reasonable North Atlantic Ocean simulation is obtained against observational data sets in a Control simulation...

Numerical modelling of the Arctic and North Atlantic exchanges with NEMO: Focus on freshwater and dynamics
DownloadFall 2018
The Arctic is currently undergoing significant changes due to increasing anthropogenic greenhouse gases causing atmospheric warming. The impact of this warming is clearly visible in the Arctic: reduced sea-ice cover, enhanced land-ice melting, increased frequency of extreme weather, etc....

Fall 2019
The rising concentration of anthropogenic heat-trapping gasses has resulted in an energy imbalance in the Earth's climate system. As a consequence of it, an enhanced hydrological cycle and the continuous decline of the ice sheets are expected to increase the freshwater input into the Arctic and...

Overturning in the subpolar North Atlantic program: A new international ocean observing system

Zika, J. , Inall, M., Pillar, H., Zhao, J., Li, F., Lozier, M., Bower, A., Houpert, L., Yang, J., Bacon, S., Greenan, B., Holliday, N., Thierry, V., Marshall, D., Heimbach, P., Weller, R., Pickart, R., Lin, X., Cunningham, S., Karstensen, J., Wilson, C., Johnson, H., deYoung, B., Gary, S., Williams, R., Straneo, F., Mackay, N., Johns, W., Fischer, J., Mercier, H., de Jong, M., de Steur, L., Myers, P.
For decades oceanographers have understood the Atlantic meridional overturning circulation (AMOC) to be primarily driven by changes in the production of deep-water formation in the subpolar and subarctic North Atlantic. Indeed, current Intergovernmental Panel on Climate Change (IPCC) projections...

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...

Recent increases in Arctic freshwater flux affects Labrador Sea convection and Atlantic overturning circulation
Download2016
Chambers, Don, Dixon, Timothy H., Bonin, Jennifer, van den Broeke, M. R., Yang, Qian, Ribergaard, Mads H., Mortensen, John, Myers, Paul G.
The Atlantic Meridional Overturning Circulation (AMOC) is an important component of ocean thermohaline circulation. Melting of Greenland’s ice sheet is freshening the North Atlantic; however, whether the augmented freshwater flux is disrupting the AMOC is unclear. Dense Labrador Sea Water (LSW),...

The LAB60 simulation is a coupled ocean sea-ice model (NEMO) that uses grid refinement to achieve high resolution (1/60 of a degree) within the Labrador Sea. This simulation starts in 2002 and will cover a period of over 10 years. This video shows the relative vorticity of the upper 55m ocean...
