This site describes how and when 100-year floods occur. It states that flood designations are based on statistical averages, not on the number of years between big floods. It also suggests that it would make more sense to refer to 100-year floods as 1-in-100 chance floods. This resource is a United States Geological Survey (USGS) Fact Sheet. It can be used in teaching quantitative skills.

Researchers collect species occurrence data, records of an organism at a particular time in a particular place, as a primary or ancillary function of many biological field investigations. Presently, these data reside in numerous distributed systems and formats (including publications) and are consequently not being used to their full potential. As a step toward addressing this challenge, the Core Science Analytics, Synthesis, and Libraries (CSAS&L) program of the U.S. Geological Survey (USGS) is developing Biodiversity Information Serving Our Nation (BISON), an integrated and permanent resource for biological occurrence data from the United States. BISON will leverage the accumulated human and infrastructural resources of the long-term USGS investment in research and information management and delivery. Read the DOI Official Press Release in which BISON's public debut was announced.

The USGS CSAS&L program is also the U.S. Node of the Global Biodiversity Information Facility (GBIF), an international, government-initiated and funded effort focused on making biodiversity data freely available for scientific research, conservation and sustainable development. USGS CSAS&L, with its partners at the U.S. Department of Energy's Oak Ridge National Laboratory (ORNL), hosts a full mirror of the hundreds of millions of global records to which GBIF provides access. BISON has been initiated with the 110 million records GBIF makes available from the U.S. and is integrating millions more records from other sources each year.

Water Science ActivitiesDrip Calculator: How much water does a leaking faucet waste?

Check your faucets at home -- do any of them drip? Well, maybe it's just a small drip -- how much water can a little drip waste? True, a single drip won't waste much water. But think about each faucet in your home dripping a little bit all day long. What if every faucet in every home on your block ... in your town ... in your state also dripped? The drips would add up to a flood of water wasted down the drain.

Global change is a relatively new area of scientific study using research from many disciplines to determine how Earth systems change, and to assess the influence of human activity on these changes. The Global Change section of the Teaching Packet consists of an introduction and five activities. In teaching these activities, four themes are important: time, change, cycles, and Earth as home.

This resource contains an organized database of resources that provide geoscience data and interpretations to the Federal Land Management Agencies (FLMA) that are basic to sound policy and land-stewardship practices. U.S. Forest Service (USFS) National Forest and Bureau of Land Management (BLM) Resource Area Management Plans for the Headwaters Province are in revision, with completion dates from 1999-2003. USFS Regions 1 and 4 have made National Priority Requests for Mineral Resources Program (MRP) to provide interim products that help them meet their planning cycles. MRP is to provide geologic maps and topical studies to meet longer range goals of integrating geoscience into decision making. This project will emphasize development of digital geoscience data, GIS analyses, and interpretations to ensure that data is available for GIS-based science integration and planning.

This USGS report provides information about the effects of coal combustion on human health. It explains the hazards associated with emissions from both large-scale coal burning electrical plants and domestic cook stoves used in developing nations. In particular, the report discusses specific instances of disease related to the emission of arsenic, fluorine, selenium, thorium, uranium, and polycyclic aromatic hydrocarbons released by burning low-grade coal in poorly vented cook stoves in China.

This website is a cooperative research project between the U.S. Geological Survey (USGS), NASA, the U.S. Army Corps of Engineers, and the University of New Orleans. The goal of the project is to investigate coastal change that occurred as a result of Hurricane Katrina. The site includes aerial video, still photography, and laser altimetry surveys of post-storm beach conditions that were collected August 31 and September 1, 2005 for comparison with earlier data. The comparison data can be used to refine predictive models of coastal impacts from severe storms and aid in disaster recovery and erosion mitigation.
