Collaborative Research: St. Elias Erosion And Tectonics Project (Steep), Peter O. Koons, Phaedra Upton

University of Maine Office of Research Administration: Grant Reports

1) Refinement of a regional scale model to include an approximation of the true 3D geometry of the orogen.

2) Develop a new local-scale model that incorporates topography, GPS data, and glacial erosion processes to refine the initial results.

3) Develop a modeling experiment to test the hypothesis that the rise and fall of ice masses during glacial cycles might influence where deformation is focused at any given time.

Colle Gnifetti Ice Core (Kcc) Progress Report (Year One)—Arcadia Ice Core Proposal: Initiatives On The Science Of The Human Past, Paul Mayewski

University of Maine Office of Research Administration: Grant Reports

The Colle Gnifetti glacier of the Monta Rosa Massif on the Swiss-Italian border is perfectly situated to offer insight into the intersection of environment (climate) and culture (history of the economy, political stability, pollution, disease) in medieval Europe. While ice cores previously collected at Colle Gnifetti were sampled at state-of-the-art resolution for the time, it was nevertheless impossible to differentiate annual or finer layering in the period older than 1500 A.D. The 2013 Colle Gnifetti expedition thus sought to collect a new ice core that could be analyzed using the ultra-high-resolution laser based technology developed in the Climate Change Institute’s …

Salt Marsh Values In A Changing World: Examining Sea Level Rise On Tidal Marshes With A Surface Elevation Table, Sarah Martina Tierney

Student Research Projects

Rising seas are threatening coastal communities and putting added pressures on the natural environment. Sea level rise rates are increasing on a global scale (from 1.7 to 3.2 mm/yr). Salt marshes are not only intertidal habitats acutely influenced by sea levels, but they also provide key ecosystem services such as: buffers against storm surges, habitat for wildlife, carbon dioxide storage, and pollutant filtration. In New England, salt marshes have built at a rate of 1 to 2 mm annually over the past 4,000 years, which has kept pace with sea level rise. However, we do not know if salt marshes …
