A draft methodology to assess the potential to store carbon dioxide (CO2) in ecosystems, as well as the reduction of greenhouse gas fluxes from ecosystems, has been proposed and is open for public comments.
A new methodology to assess the nation's potential to store carbon dioxide (CO2) is available.
In response to the need for updated topographic maps, the U.S. Geological Survey (USGS) has developed and made available a new national map series called the US Topo. Production of these maps began in earnest in June 2009. In a little over a year, the USGS National Geospatial Technical Operations Center (NGTOC) has published more than 25,000 7.5-minute cells.
After a major disaster, a satellite image or a collection of aerial photographs is frequently the fastest, most effective way to determine the scope and severity of the event. With that goal, the USGS operates the Hazard Data Distribution System (HDDS) to process and deliver satellite and aerial imagery in near-real time during natural or human-caused disasters.
A recent U.S. Geological Survey study examined a compilation of state and federal fish-monitoring data for trends in mercury levels in fish from 1969 to 2005 in U.S. rivers and lakes.
The most detailed national vegetation U.S. land-cover map to date was released today by the U.S. Geological Survey (USGS). The map will enable conservation professionals to identify places in the country with sufficient habitat to support wildlife.
The U.S. Geological Survey will receive nearly unlimited access to imagery collected by Spot Image satellites over the continental United States under a major data purchase agreement announced today. The mid-resolution earth observation data from SPOT 4 and 5 satellites are similar to imagery acquired by aging U.S. Landsat satellites.
The presence of the invasive diatom Didymosphenia geminata, or didymo, has been confirmed in remote Chilean rivers near Esquel, Argentina, by a U.S. Geological Survey scientist and diatom expert.
To assist in responding to the Deepwater Horizon oil spill, the U.S. Geological Survey has developed a new tool to rapidly distribute the latest USGS topographic maps of the Gulf Coast region.
An estimated 223 trillion cubic feet (tcf) (mean estimate) of undiscovered, technically recoverable natural gas are in the Nile Delta Basin Province, located in the Eastern Mediterranean region.
Large amounts of nitrogen are stored in the soils of agricultural areas in Nebraska and Maryland, according to a new study by the U.S. Geological Survey and the U.S. Department of Agriculture. Once in the soil, nitrogen can be converted to nitrate, which can readily move to groundwater.
At the Association of American Geographers (AAG) Annual Meeting, April 14-18, in Washington, DC, more than 80 USGS scientists will make presentations on topics ranging from advances in digital mapping to spatial analysis of risk management, from remote sensing of drought to historical land use. The conference is the world's largest gathering of geographers.
