Modeling the paleocirculation of the Mediterranean: The Last Glacial Maximum and the Holocene with emphasis on the formation of sapropel S1
Download1998
Myers, Paul G., Rohling, Eelco J., Haines, Keith
An ocean general circulation model is used to simulate the thermohaline circulation in the Mediterranean sea during the last glacial maximum and the Holocene, when the sapropel S1 was deposited. The model is forced by prescribed surface temperatures and salinities, where present-day values lead...

Hirschi, Joel J. M., Barier, Bernard, Boning, Claus, Biastoch, Arne, Blaker, Adam T., Coward, Andrew, Danilov, Sergey, Drijfhout, Sybren, Gezlaff, Klaus, Griffies, Stephen M., Hasumi, Hiroyasu, Hewitt, Helene, Iovino, Doroteaciro, Kawasaki, Takao, Kiss, Andrew E., Koldunov, Nikolay, Marzocchi, Alice, Mecking, Jennifer V., Moat, Ben, Molines, Jean-Marc, Myers, Paul G., Penduff, Thierry, Robert, Malcolm, Treguier, Anne-Marie, Sein, Dmitry V., Sidorenko, Dmitry, Small, Justin, Spence, Paul, Thompson, LuAnne, Weijer, Wilbert, Xu, Xiaobiao
The Atlantic meridional overturning circulation (AMOC) represents the zonally integrated stream function of meridional volume transport in the Atlantic Basin. The AMOC plays an important role in transporting heat meridionally in the climate system. Observations suggest a heat transport by the...

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...

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...

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...

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),...

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...

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...

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...
