Effect of a variable eddy transfer coefficient in an eddy-permitting model of the subpolar North Atlantic Ocean
Download2005
The effect of using a variable eddy transfer coefficient for the Gent–McWilliams (GM) parameterization in a (1/3)°-resolution ocean model of the subpolar North Atlantic Ocean is investigated. Results from four experiments with different implementations of this coefficient are compared among...

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...

Kulan, Nilgun, Ribergaard, Mads H., Myers, Paul G.
We examine the historical variability of Irminger Water (IW) along 3 sections across the West Greenland Current over 1950–2005. Significant variability in the salinity, size and position of the IW core are seen over time. Some of the saltiest and warmest IW ever recorded have been seen since 1995...

Decline and partial rebound of the Labrador Current 1993-2004: Monitoring ocean currents from altimetric and conductivity-temperature-depth data
Download2010
Chen, Nancy, Ohashi, Kyoko, Fischer, Jürgen, Myers, Paul G., Han, Guoqi, Nunes, Nuno
Monitoring and understanding of Labrador Current variability is important because it is intimately linked to the meridional overturning circulation and the marine ecosystem off northeast North America. Nevertheless, knowledge of its decadal variability is inadequate because of scarcity of current...

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...

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...

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...

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...

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...

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°,...
