This database and accompanying report demonstrate the potential of combining observed river discharge information with a climate-driven Water Balance Model in order to develop composite runoff fields that are consistent with observed discharges. This combination preserves the accuracy of discharge measurements as well as the spatial and temporal distribution of simulated runoff, providing a 'best ... Full description.

Wilson Alwyn Bentley (1865-1931), famous for his photomicrographs of snow crystals, prepared sets of glass lantern slides of dew, frost and ice crystals. Many of these sets found their way to colleges and universities around the United States. The University of Wisconsin's Department of Atmospheric and Oceanic Sciences donated their collection to the Schwerdtfeger Library in 2000. Shortly after, the ... Full description.

This portal provides access to a variety of educational and supporting materials for students and teachers of microbiology about the ecology, diversity and evolution of micro-organisms. Materials include information about microorganisms, extremophiles, and extreme habitats. There is also information about the Microbial Observatories (MO), research projects to study extremophiles and their environments ... Full description.

This site describes snow crystals and snowflakes. Although a common meteorological phenomenon, snow crystal growth is a fascinating and poorly understood process, in which remarkably complex and beautifully symmetric structures appear, quite literally, out of thin air. The many facets of snow crystals are described here, along with the attempts to understand their formation. Site highlights include ... Full description.
