Alaska's Redoubt volcano, near Anchorage, Alaska, began erupting March 22, 2009 and has done so six times in the past two days. Mount Redoubt has erupted three other times in the 20th century: 1902, 1966, and 1989.
There are many sources of information available about Mt. Redoubt's most recent eruptions. The USGS Newsroom has updates about recent activity. The Alaska Volcano Observatory has frequently updated information and images of Redoubt and other volcanoes in the area. Additionally, NASA's Earth Observatory is releasing imagery from its Moderate Resolution Imaging Spectroradiometer (MODIS) which is mounted on the Terra satellite.

The Contra Costa County Community Development Department has made the Contra Costa County Watershed Atlas available in both print and online as a pdf. From the publication's site: "The Contra Costa County Watershed Atlas is a large format, full color, 150-page book of maps, statistics and text about the 28 major watersheds in the County. Though focused on the state of natural ecosystems on the watershed scale, the Atlas also provides information about the human community and the county as and eco-region."
"Additionally, the Atlas includes the complete CCWF Creek and Wetland Enhancement Project Database, samples of GPS data collected by community groups on creeks. Maps provided at a countywide scale include: watersheds, creeks, political boundaries (cities, spheres of influence and unincorporated communities), planned land use, demographic data, topography, hydrology, earthquake fault lines, flood plains, soils, aspect, slope, vegetative cover, temperature, rainfall, impervious surface, historical and current steelhead trout populations and color aerial photographs."
The atlas is available online and in print at the Water Resources Center Archives. Copies of the atlas are also available for purchase from the Contra Costa County Community Development Department.
The Integrated Ocean Drilling Program (IODP) has made the location and scientific information about each of its core locations available in Google Earth. The KML file displays the precise location (latitude and longitude) of each core and gives scientific information including data about the hole, core sample, and links to related data. Additionally, users can download a broad range of data for each core location.
The data comes from "the Core Data from the Deep Sea Drilling Project Legs 1-96 CD-ROM produced in 2000 by the U.S. Department of Commerce, National Oceanic and Atmospheric Administration, National Environmental Satellite, Data, and Information Service, National Geophysical Data Center, and collocated World Data Center for Marine Geology and Geophysics, Boulder. Data were compiled in cooperation with the U.S. Science Support Program, the Joint Oceanographic Institutions, Inc., and the U.S. National Science Foundation."
Library patrons can access both Google Earth and Google Earth Pro at the Earth Sciences and Map Library.
NASA has made a new remote sensing tool, Giovanni, available online. "Giovanni is a Web-based application developed by the GES DISC that provides a simple and intuitive way to visualize, analyze, and access vast amounts of Earth science remote sensing data without having to download the data. Giovanni is an acronym for the GES-DISC (Goddard Earth Sciences Data and Information Services Center) Interactive Online Visualization ANd aNalysis Infrastructure."
Giovanni is made available in four different categories of instances:
