PDF Acid Rain in Shenandoah National Park, Virginia [More info]
Explains acidity and acid rain and how it affects aquatic organisms. Describes the effect of acid rain on this national park, identifying areas that are at greater or lesser risk from acid rain.
PDF Advanced Remote Sensing Research [More info]
New and experimental methods of analyzing geospatial imagery, including detailed spectral analysis of land surface materials, historical image analysis, and long wave infrared image analysis.
Alaska Geospatial Data Clearinghouse [More info]
Clearinghouse for the description and availability of multiple geospatial datasets relating to Alaska from many federal, state and local cooperating agencies under the coordination of the Alaska Geographic Data Committee.
PDF An Overview of the GIS Weasel [More info]
Software system designed to aid users in preparing spatial information as input to lumped and distributed parameter environmental simulation models.
ANALOG: a program for estimating paleoclimate parameters using the method of modern analogs [More info]
Scientific software used with faunal or floral census data to find the modern locations most similar to any given fossil assemblage. Source code is included.
PDF Anticipated effects of development on habitat fragmentation and movement of mammals into and out of the Schoodic District, Acadia National Park, Maine [More info]
Wildlife you see in a national park or other reserved area don't know about the park boundary. Bobcat, martens, mink, and moose need different types of living space and habitat. Development outside the park affects their ability to inhabit the park.
PDF Application of the SPARROW watershed model to describe nutrient sources and transport in the Missouri River Basin [More info]
Maps and diagrams showing how the mathematical model predicts the distribution of various pollutants within a large watershed.
PDF Assessing carbon stocks, carbon sequestration, and greenhouse-gas fluxes in ecosystems of the United States under present conditions and future scenarios [More info]
Congress asked us (in the Energy Independence and Security Act of 2007) to figure out how to assess the effects of carbon storage, sequestration, and greenhouse gas fluxes in our ecosystems. Here's how we plan to do that.
PDF Assessing groundwater availability in the North Atlantic Coastal Plain aquifer system [More info]
Nature, history, and distinctive characteristics of this aquifer system help us to understand the likely distribution of available groundwater.
Assessing the vulnerability of public-supply wells to contamination--Edwards aquifer near San Antonio, Texas [More info]
Well vulnerability results from the young age of groundwater. Karst features permit contaminants to move into the aquifer easily, leading to a well mixed aquifer; geochemical processes do not degrade contaminants quickly.
