An integrated geospatial approach to monitoring the Bering Glacier system, Alaska
The Bering Glacier is the largest and longest glacier in continental North America, with an area of approximately 5,175 km2, and a length of 190 km. It is also the largest surging glacier in America, having surged at least five times during the twentieth century. The last surge of the Bering Glacier occurred in 1993-1995, since then, the glacier has undergone constant and significant retreat there

An intensity scale for riverine flooding
Recent advances in the availability and accuracy of multi-dimensional flow models, the advent of precise elevation data for floodplains (LIDAR), and geographical GIS allow the creation of hazard maps that more correctly reflect the varying levels of flood-damage risk across a floodplain when inundatecby floodwaters. Using intensity scales for wind damages, an equivalent water-damage flow intensity

Analysis of summer 2002 melt extent on the Greenland ice sheet using MODIS and SSM/I data
Previous work has shown that the summer of 2002 had the greatest area of snow melt extent on the Greenland ice sheet ever recorded using passive-microwave data. In this paper, we compare the 0?? isotherm derived from the Moderate-Resolution Imaging Spectroradiometer (MODIS) instrument, with Special Sensor Microwave/Imager (SSM/I)-derived melt, at the time of the maximum melt extent in 2002. To val

Application of cross-borehole radar to monitor fieldscale vegetable old injection experiments for biostimulation
Cross-borehole radar methods were used to monitor a field-scale biostimulation pilot project at the Anoka County Riverfront Park (ACP), located downgradient of the Naval Industrial Reserve Ordnance Plant, in Fridley, Minnesota. The goal of the pilot project is to evaluate biostimulation using emulsified vegetable oil to treat ground water contaminated with chlorinated hydrocarbons. Vegetable oil i

Assessment of uncertainty in ROLO lunar irradiance for on-orbit calibration
A system to provide radiometric calibration of remote sensing imaging instruments on-orbit using the Moon has been developed by the US Geological Survey RObotic Lunar Observatory (ROLO) project. ROLO has developed a model for lunar irradiance which treats the primary geometric variables of phase and libration explicitly. The model fits hundreds of data points in each of 23 VNIR and 9 SWIR bands; i

Atmospherically transported elements and deposition in the Southeastern United States: Local or transoceanic?
Saharan dust is persistently transported and deposited in ecosystems of the western Atlantic Ocean. This dust is an aggregate of clay and quartz particles cemented with Fe oxides. Samples collected and analyzed from Mali (central Africa), the Azores, the Caribbean and the Eastern United States document the levels of minor and trace metals in the dust. Metal loadings, particularly the toxic element

Baseline practices and user needs for Web dissemination of geotechnical data
This paper presents the findings and recommendations of the User Scenario Work Group (USWG) in identifying a baseline of current practices within the geo-professional community and prioritizing desired functional requirements in the development of a comprehensive geotechnical information management system. This work was conducted as an initial phase of a larger project to demonstrate the effective

Beliefs and attitudes toward lethal management of deer in Cuyahoga Valley National Park
We used the theory of reasoned action to help understand attitudes and beliefs about lethal management of deer (Odocoileus virginianus) in Cuyahoga Valley National Park (CVNP), Ohio. We used a mail-back survey to collect data from Ohio residents in the surrounding 9-county area. Two strata were defined: residents

Bog iron formation in the Nassawango Creek watershed, Maryland, USA
The Nassawango bog ores in the modern environment for surficial geochemical processes were studied. The formation of Nassawango bog ores was suggested to be due to inorganic oxidation when groundwater rich in ferrous iron emerges into the oxic, surficial environment. It was suggested that the process, providing a phosphorus sink, may be an unrecognized benefit for mitigating nutrient loading from
