Database Management Science Questions and Goals Climate change

Database Management

Science Questions and Goals • Climate change; permafrost and soils – Indicator of climate change – Impact on permafrost • Anthropogenic impact – Degradation on human impact • Paleoclimate • Subglacial permafrost – Impact on ice sheet dynamics • Driver of changes in polar ecosystems – Soils form important interface and habitat – Impacts of physical and chemical soil changes on biota

Overview • Design issues • Input, database, final product • Input objects and attributes • Database (tables, rules, etc. ) • Output

Design, components • Coverage • Scale • Content

Input data, existing databases I. • Point data – Campbell – Bockheim – VALMAP – TAMARA/OSU • Aerial Photos • Orhtophotos

Input data, existing databases II. • • Land cover Satellite imagery DEMs Geologic maps Dry Valleys GIS Geomorphologic maps Soils Maps

Content • Objects – Points, Polygons, Lines, Rasters, Grids • Database – Tables – Rules • Products – General maps • Soil • Permafrost – Flexible rules – Individual research • Processing at separate site

Initial Product • Build soil temperature model – Existing data – Existing knowledge • Doable in 2 -3 years

Soils map justification • • Establish baseline Biodiversity Measure changes in ecosystem Simplified ecosystems for application to more complex systems elsewhere • Influence on ecosystem • Filter and integrator
