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...

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 mixed layer depth (meters) from 2004 through...

Modeling the transport of cryoprotective agents in articular cartilage for cryopreservation
DownloadSpring 2011
Loading vitrifiable concentrations of cryoprotective agents is an important step for cryopreservation of biological tissues by vitrification for research and transplantation purposes. This may be done by immersing the tissue in a cryoprotective agent (CPA) solution, and increasing the...

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...

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...

The Dual Failure Restorability (DFR) problems involve the design of network topology to be restorable in the event of single and dual failures scenarios. We developed new integer linear programming (ILP) models to optimally design mesh topology networks with various survivability schemes; span...

Nano-scale studies of the assembly, structure and properties of hybrid organic-silicon systems
DownloadFall 2011
Advancements in the field of electronics might be achieved by future molecular scale devices. Hybrid organic-silicon structures have the potential to overcome many challenges facing the use of molecules as devices while maintaining the ability to interface with traditional silicon technology. The...

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...

Higher latitudes have experienced a significant change in climate and physical processes within recent years. This study focuses on the Greenland Ice Sheet and surrounding ocean waters. It has been shown that relatively warm ocean waters may accelerate melt production of marine terminating...

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...
