Boron In Antarctic Granulite-Facies Rocks: Under What Conditions Is Boron Retained In The Middle Crust?, Edward S. Grew
Boron In Antarctic Granulite-Facies Rocks: Under What Conditions Is Boron Retained In The Middle Crust?, Edward S. Grew
University of Maine Office of Research Administration: Grant Reports
This award, provided by the Antarctic Geology and Geophysics Program of the Office of Polar Programs, supports a project to investigate the role and fate of Boron in high-grade metamorphic rocks of the Larsemann Hills region of Antarctica. Trace elements provide valuable information on the changes sedimentary rocks undergo as temperature and pressure increase during burial. One such element, boron, is particularly sensitive to increasing temperature because of its affinity for aqueous fluids, which are lost as rocks are buried. Boron contents of unmetamorphosed pelitic sediments range from 20 to over 200 parts per million, but rarely exceed 5 parts …
The Science Behind Climate Change: A Journey To Reedy Glacier, Brenda L. Hall, Molly Schauffler
The Science Behind Climate Change: A Journey To Reedy Glacier, Brenda L. Hall, Molly Schauffler
University of Maine Office of Research Administration: Grant Reports
This Communicating Research to Public Audiences project focuses on the Reedy Glacier Antarctic research of Brenda Hall (OPP 0229034) and its relevance to the residents of and visitors to Maine. Collaborators include the University of Maine, the Maine Discovery Museum, the Acadia National Park and Cadillac Mountain Sports (an environmentally active retail company with several stores around the state). The primary deliverable is the development of an interactive software program that presents information and experiences in a two-tiered concept approach -- on the Reedy Glacier and its connection to Maine and on the process of science. The software is being …
Us Itase Glaciochemistry Phase 2: East Antarctica, Paul Mayewski
Us Itase Glaciochemistry Phase 2: East Antarctica, Paul Mayewski
University of Maine Office of Research Administration: Grant Reports
This award supports a project to undertake glaciochemical investigations of the Ross Sea Embayment Drainage System, and portions of Wilkes Land for purposes of understanding annual to multi-centennial scale climate variability. The glaciochemical data that will be collected will contribute to the U.S. component of the International Trans-Antarctic Scientific Expedition and will occur over a period of two years on an overland traverse that will begin at Taylor Dome in Northern Victoria Land and travel to the South Pole. This data, along with similar information collected on a series of earlier traverse in West Antarctica, will contribute to providing an …
A Science Management Office For The United States Component Of The International Trans Antarctic Expedition (Us Itase Smo) - A Collaborative Program Of Research From Taylor Dome To, Paul Mayewski
University of Maine Office of Research Administration: Grant Reports
This award supports the science management office (SMO) for a series of collaborative science proposals that are part of the U.S. contribution to the International Trans-Antarctic Scientific Expedition (US ITASE). It supports the science administration and the coordination of logistics needed in order to accomplish the research. The SMO will work with the Antarctic support contractor to coordinate field operations for the traverse platform so that US ITASE can undertake a series of scientific traverses in the region from Taylor Dome, in Northern Victoria Land to South Pole (NVL-SP) inclusive of interior portions of the East Antarctic plateau such as …
Collaborative Research: Erosional Forcing Of Late Quaternary Compressive Strain, West Central Taiwan, Phaedra Upton
Collaborative Research: Erosional Forcing Of Late Quaternary Compressive Strain, West Central Taiwan, Phaedra Upton
University of Maine Office of Research Administration: Grant Reports
The concept of steady-state growth of compressive orogens is one of the most accepted ideas in continental tectonics developed in the last two decades, yet surprisingly few direct data exist to test the models that have been advanced. Testing and refining the concept of steady-state mountain building requires identification of cases of transient response and dynamic feedback in compressive orogens, and documentation of the spatial and temporal scales at which crustal deformation responds to erosion. This project takes advantage of a unique natural experiment in the active fold-thrust belt of west-central Taiwan where enough modern seismologic, geodetic, structural and geochronologic …
Embedded Ice Sheet Model, James L. Fastook
Embedded Ice Sheet Model, James L. Fastook
University of Maine Office of Research Administration: Grant Reports
This award supports the development of an embedded ice sheet model, one where a section of the ice sheet (at a mesoscale) is modeled at higher resolution, but is driven by output from a lower-resolution model of the entire ice sheet (at a global scale). In addition to giving higher resolution results, it will be better able to capture the behavior of small-scale, but dynamically important, systems such as ice streams. It will also be possible with the new embedded model to include more complete physics (such as longitudinal stresses). This project will enable the continued development and application of …
