A global hydrological database is considered essential for research and application-oriented hydrological and climatological projects at global, regional and basin scales. This includes water balance studies, investigation of trends in long-term hydrological time series, coupling of hydrological and meteorological models, flux of fresh water and pollutants into the oceans, and the coupling of runoff ...

This site provides tabular and graphical information on both tidal height and current strength for a wide variety of locations on both the Pacific and Atlantic coasts of the Americas, as well as most islands in those two oceans. The user first selects a region and then from that page selects a site for which to generate predictions. There is a form for customized predictions which allows the user ... Full description.

Window To My Environment (WME) is a web-based tool that provides access to a wide range of federal, state, and local information about environmental conditions and features in an area of your choice. By entering your zip code or city/town and state WME will provide an interactive map that shows the location of regulated facilities, monitoring sites, water bodies, population density, and perspective ...

In this activity, users download and graph modeled climate data to explore variability in climate change. Most people know that climate changes are predicted over the next hundred years, but they may not be aware that these changes are likely to vary from region to region. Using data from the University of New Hampshire's Earth Science Information Partner, a digital library of Earth Science data, ... Full description.

This 5-minute animation portrays fluctuations in the cryosphere through observations collected from a variety of satellite-based sensors. The cryosphere consists of those parts of the Earth's surface where water is found in solid form, including areas of snow, sea ice, glaciers, permafrost, ice sheets, and icebergs. In these regions, surface temperatures remain below freezing for a portion of each ... Full description.

Discovering Plate Boundaries is based on 5 world maps containing earthquake, volcano, topography, satellite gravity, and seafloor age data. The novel aspect of the exercise is the "jigsaw" manner in which student groups access the maps and use them to discover, classify, and describe plate boundary types. The exercise is based only on observation and description, which makes it useful at a wide variety ... Full description.
