This journal article discusses how exposing creeks, rivers, and stormwater drainage to daylight can improve water quality and hydraulic capacity. Daylighting projects deliberately expose some or all of the flow of a previously covered drainage, offering the potential to recreate wetlands, ponds, and estuaries, and ultimately reducing the levels of organic and inorganic pollutants in the water. The ... Full description.

Information is provided about water concerns and issues in the Middle East. The material includes several articles about water policy in the region, where many countries suffer from water shortages. The scarcity of water is used as a political issue and lever, particularly as population growth has historically expanded to the limits of the scarcest available resource. In the Middle East, this resource ... Full description.

This document provides activities and ideas for science projects that deal with water supply and quality in the Jacksonville, Florida area. Topics include the use of groundwater (and wells) as a resource, types of groundwater contamination, and information on the aquifers in the Jacksonville area. An activity is provided in which students construct a model aquifer, and suggestions are made for science ... Full description.

For ecologists, the horseshoe crab is an important creature- a vastly adaptable organism that predates most species on the planet, with a lifecyle that is interlocked with other animals. Users can view information, photographs, and diagrams that explain the anatomy, range and habitat, lifecycle, ecological niche, reproductive cycle, and medical uses of the horseshoe crab.

Users download and analyze satellite images showing the amount of ozone in the stratosphere. They interpret the images to identify the ozone "hole" that develops over Antarctica each summer, and compare its size from year to year. Using freely available image analysis software, ImageJ, users quantify the area of the Antarctic ozone hole each October from 1996 to 2004. Finally, they bring their measurements ...

The National Atmospheric Deposition Program monitors wet atmospheric deposition (chemical constituents deposited from the atmosphere via rain, sleet and snow) at over 220 National Trends Network sites throughout the United States. This site contains a long-term, high-quality database of atmospheric deposition for research support in the areas of acid rain, air quality, water quality, agricultural ... Full description.

This module provides three activities that explore the potential impact of climate variability and change on Earth's most abundant resource, water. Although each activity is designed to tap specific skills and knowledge to yield scientific results, the broader intent is to stimulate thought about the long-term impacts of a warmer planet. Through participation in these activities, students will observe ... Full description.

Visitors can access a variety of information on global warming, emissions and impacts of greenhouse gases, and what is being done to evaluate and remedy the effects of a changing climate. Interactive calculators are available online for assistance with estimating greenhouse gas emissions of specific activities and evaluating emission reduction opportunities. A searchable database by topic, information ... Full description.
