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...

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...

Response of the Mediterranean Sea thermohaline circulation to observed changes in the winter wind stress field in the period 1980-1993
Download1999
Josey, Simon, Samuel, Sarah, Myers, Paul G., Haines, Keith
This paper seeks to model changes in deep water production in the eastern Mediterranean induced by changes in winter wind stress. An analysis of individual monthly wind stress fields over the Mediterranean for 1980–1993 from the SOC flux data set shows that an intensification of the winter mean...

Role of adventitious roots in water relations of tamarack (Larix laricina) seedlings exposed to flooding
Download2012
Calvo-Polanco, M., Senorans, J., Zwiazek, J.J.
Background: Flooding reduces supply of oxygen to the roots affecting plant water uptake. Some flooding-tolerant tree species including tamarack (Larix laricina (Du Roi) K. Koch) produce adventitious roots in response to flooding. These roots were reported to have higher hydraulic conductivity...

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...

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...
