• A Global Map of Human Impacts to Marine Ecosystems | NCEAS: Many people may wonder what happens in the vast stretches of the world's oceans. For some, it is simply a matter of "out of sight, out of mind". Fortunately that is not the attitude at the National Center for Ecological Analysis and Synthesis at the University of California, Santa Barbara. For one of their latest projects, they decided to estimate and visualize the global impact humans are having on the ocean's ecosystems. Visitors to the site can view the map, learn about the methodology used to create the map, and also read about their datasets. Their findings were also recently reported in Science magazine, and users can view supplementary findings which appeared in that piece. As it stands, this map provides "critical information for evaluating where certain activities can continue with little effect on the oceans, where other activities might need to be stopped or moved to less sensitive areas, and where to focus efforts on protecting the last pristine areas.

• Research Projects - Emerging Contaminants in the Environment: Synthetic or naturally-occu rring chemicals or microorganisms not commonly monitored in the environment may have adverse ecological or human health effects. Read about a number of USGS projects designed to define these emerging contaminants and examine their role in the health of our water.

• Natural Hazards Gateway: The USGS Natural Hazards Gateway offers a one-stop shop to learn about natural hazards (earthquakes, floods, hurricanes, landslides, tsunamis, volcanoes, and wildfires). The site also links to real-time data that can be useful to citizens and emergency support personnel who must make important decisions before, during, and after a natural disaster.

• Using an Earth System Approach: "Since about 1980, an important paradigm has emerged in the geosciences, analogous to the plate tectonics revolution of the 1950s and 1960s. This paradigm, called "Earth System Science" or simply "Earth System," acknowledges that changes in the solid earth (land - lithosphere or geosphere) result from interactions among the atmosphere (air), hydrosphere (water, including oceans, rivers, ice), biosphere (life) and the lithosphere... ."

• A Framework for Ecological Risk Assessment: In 1972, Congress passed the Federal Water Pollution Control Act, commonly known as the Clean Water Act (CWA). Under the CWA, point source discharges (i.e., discharges from municipal and industrial facilities) to waters of the United States must obtain a National Pollutant Discharge Elimination System (NPDES) permit, which requires compliance with technology- and water quality-based treatment standards. In addition, because of the complexity and ecological significance of marine ecosystems, discharges to the territorial seas and beyond must also comply with section 403 of the CWA, which specifically addresses impacts from such point sources on marine resources. The section 403 program was one of the first of EPA's programs to incorporate ecological risk assessment as part of the evaluation of the impacts of point source discharges on the marine environment.
