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.

In this article, The Why Files examines the possible finding of water ice on our Moon, and the implications for this discovery. The article discusses why scientists believe there is water on the Moon, how a neutron spectrometer picks up the unusual presence of hydrogen on the Moon which could indicate water, what scientists hope to use this water for, and where this water may have come from. A moon ... Full description.

In this lesson plan students will learn the basics about how tornadoes are formed, and where and when they are most likely to occur. They will then study the current research on tornadoes and explore how scientists are trying to predict them. They will learn about the equipment storm chasers use to study tornadoes and will develop their own research plans. Full description.

Imagine the Universe is dedicated to discussion about the universe, how it is evolving, and the kinds of objects and phenomena it contains. The site is intended for students age 14 and up and is a service of NASA's High-Energy Astrophysics Science Archive Research Center (HEASARC). Contained within this site are explanations of the concepts and principles used to study and understand the universe, ... Full description.

The U.S. ice coring community has, in concert with its international partners, made remarkable strides to advance in the understanding of global change. This document was assembled by the Ice Core Working Group (ICWG), and provides a synthesis of the global change lessons learned thus far, and the requirements and plans for solving new global change questions utilizing future ice coring activities. ...

Glacier Peak in north-central Washington state is not prominently visible from any major metropolitan centers, and so its attractions, as well as its hazards, tend to be overlooked. Yet, Glacier Peak has produced larger and more explosive eruptions than any other Washington volcano except Mount St. Helens. In the past 14,000 years, Glacier Peak has erupted at least a dozen times, most recently around ... Full description.

This site is home to the Crooked River Project. Developed by youth in Ohio, the Crooked River Project consisted of students studying the Cuyahoga River. This page provides information about the Cuyahoga River on the following subjects: watershed, history, water quality, pollution, recreation, organisms, and reason for concern. Links to other years of this project are available as well. Full description.

This web page describes the lahars that swept down the Drift River Valley during the 1989-90 eruption of Redoubt Volcano, Alaska, and the testing of a new experimental detection and warning system designed to track lahars and debris flows and to give warning to people downstream. In this case, an oil-storage facility in the Cook Inlet area was at risk. The seismometers used (acoustic-flow monitors) ... Full description.
