A Magnitude 7.1 Earthquake in the Tacoma Fault Zone-A Plausible Scenario for the Southern Puget Sound Region, Washington [More info]
Scientific description of the likely effects of a significant earthquake on this densely populated area.
A Method for Qualitative Mapping of Thick Oil Spills Using Imaging Spectroscopy [More info]
A method to create qualitative images of thick oil in oil spills on water using near-infrared imaging spectroscopy data. It relies on the organic absorption features of chemical bonds in aliphatic hydrocarbons. The data cannot give oil volume estimates.
PDF A New Method for Mapping Population Distribution [More info]
With the addition of elevation and land use and land cover data, we can show population density on a map much more effectively than if we simply color census areas. The resulting maps should allow better planning, especially in highly developed areas.
PDF A new tool to assess groundwater resources in the Mississippi embayment [More info]
Mathematical model of the groundwater system in this area includes 13 types of data and spans multiple aquifers over more than a century. This enables us to assess the quantity of groundwater, where and how it is being used, and how pumping affects it.
A program for the conversion of The National Map data from proprietary format to resource description framework (RDF) [More info]
To expand data functionality and capabilities for users of The National Map of the U.S. Geological Survey, data sets for six watersheds and three urban areas were converted from the Best Practices vector data model formats to Semantic Web data formats.
PDF A spatial analysis of cultural ecosystem service valuation by regional stakeholders in Florida: a coastal application of the social values for ecosystem services (SolVES) tool [More info]
Research project to close gaps in our knowledge about the attitudes and perceptions, or nonmonetary values, held by coastal residents for ecosystem services, particularly for cultural services.
PDF A westward extension of the tropical Pacific warm pool leads to March through June drying in Kenya and Ethiopia [More info]
Analysis of sea-surface temperature in the Indian Ocean shows that warming correlates with east African rainfall; the effect on atmospheric convection and precipitation over the Indian Ocean is greater than that associated with El Niño (ENSO).
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 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.
