Part of NASA's Earth Observing System (EOS), the Aqua satellite mission is gathering information on the Earth's atmosphere, oceans, and land surface to help scientists understand the role of hydrology and its impact on climate. The website features introductions of the science team, information on the data products, and summaries and fact sheets of the four science groups involved with the Aqua...

Spearheaded by the US Environmental Protection Agency (EPA) and the US Geological Survey (USGS), the National Hydrography Dataset (NHD) is "a comprehensive set of digital spatial data that encodes information about naturally occurring and constructed bodies of water, paths through which water flows, and related entities." The dataset is useful in the creation of maps, in geocoding observations...

Until now, geoscientists believed that spreading ridges under the Arctic Ocean were too slow-spreading and cool to vent molten rock. An article published this month in Nature details sonar data revealing two young volcanoes under Arctic waters. Dr. Marago H. Edwards of the University of Hawaii led the exploration team in which civilian scientists worked in cooperation with the Navy, using a...
