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,...

Mathematical modeling of nitrous oxide emissions from an agricultural field during spring thaw
Download1999
Confidence in regional estimates of N2O emissions used in national greenhouse gas inventories could be improved by using mathematical models of the biological and physical processes by which these emissions are known to be controlled. However these models must first be rigorously tested against...

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...

Minimizing invasion risk by reducing propagule pressure: a model for ballast-water exchange
Download2005-01-01
Lewis, Mark A., Wonham, Marjorie J., MacIsaac, Hugh J.
Biological invasions are a major and increasing agent of global biodiversity change. Theory and practice indicate that invasion risk can be diminished by reducing propagule pressure, or the quantity, quality, and frequency of introduced individuals. For aquatic invasions, the primary global...

Origin of the interhemispheric potential mismatch of merging cells for interplanetary magnetic field BY‐dominated periods
Download2007
Kabin, Konstantin, Rankin, Robert, Gombosi, Tamas I., Sofko, George J., Ridley, Aaron J., Watanabe, Masakazu, Clauer, C. Robert
When the dawn-to-dusk component of the interplanetary magnetic field (IMF B-Y) is dominant, ionospheric convection exhibits a basic two-cell pattern with significant dawn-dusk and interhemispheric asymmetries. For IMF B-Y > 0 the duskside merging cell potential in the Northern Hemisphere is much...

Overturning in the subpolar North Atlantic program: A new international ocean observing system
Download2017
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...

Pacific Water Pathway in the Arctic Ocean and Beaufort Gyre in Two Simulations With Different Horizontal Resolutions
Download2019-01-01
Hu, Xianmin, Myers, Paul G., Lu, Youyu
A set of numerical simulations (with horizontal resolutions of 1/4 degrees and 1/12 degrees ) is conducted to study the Pacific Water pathway in the Arctic Ocean and the freshwater content in Beaufort Gyre. Passive tracer tags the Pacific Water entering through Bering Strait into the Arctic Ocean...

Serpe, Michael J., Islam, Molla R.
In this submission we fabricated a humidity-responsive polymer-based actuator by layering negatively charged poly(N-isopropylacrylamide)-co-acrylic acid microgels and positively charged poly(diallyldimethyl ammonium chloride) on top of a flexible plastic substrate. We show that the extent of the...
