Changing Arctic ecosystems-Research to understand and project changes in marine and terrestrial ecosystems of the Arctic
Three themes of ongoing research: forecasting polar bear and walrus population response to changing marine ecosystems; measuring wildlife population changes in the Arctic coastal plain, and wildlife communities in the boreal-Arctic transition zone.
Changing Arctic Ecosystems: Updated forecast: Reducing carbon dioxide (CO2) emissions required to improve polar bear outlook
Polar bears are endangered by reduction in Arctic sea-ice concentration and by reduction in their supply of prey for food. Models shown here indicate anticipated effects on polar bear populations of several climate change scenarios.
Community model for coastal sediment transport
Description of the National Community Sediment-Transport Model (NCSTM), an open source numerical model for sediment transport in coastal regions.
Decision-support systems for natural-hazards and land-management issues
Three mathematical models using information about the geographic distribution and character of land surface characteristics along with proposed modifications or plausible events to determine the likely costs and benefits of actions and events.
Development of computational fluid dynamics--habitat suitability (CFD-HSI) models to identify potential passage--Challenge zones for migratory fishes in the Penobscot River
Proposed removal of dams will change the characteristics of stream flow and will affect fish that swim upstream to spawn. A mathematical model of the river flow tells us where the likely problems will be located and how the flow will change.
Discontinuous nature of kriging digital terrain models
Research exploring the mathematical properties of kriging, a widely-used surface interpolation method. The continuity properties of kriging digital terrain models over a wide range of terrain types helps hydrologists assess the usefulness of kriging for D
Drought Monitoring with VegDRI
The Vegetation Drought Response Index is a drought monitoring and mapping tool integrating satellite observations of vegetation and climate with land cover, soil characteristics, and other environmental factors.
