Categories: Animals/Wildlife,Climate Change,Energy,Geology/Mining,Govt Finance,Natural Resources,Recreation/Travel

Discusses issues involved in questions of federal land acquisition and management.  From the Congressional Research Service, posted by the Federation of American Scientists


Chirp Seismic-Reflection Data from the Baltimore, Washington, and Norfolk Canyons, U.S. Mid-Atlantic Margin

Categories: Defense/Military,Geology/Mining,Science/Technology,Virginia Issues

Part of a larger project to investigate mid-Atlantic margin Holocene geological activity and assess the area’s potential to generate submarine geohazards.  From the U.S. Geological Survey


Geologic Map of Mars

Categories: Geology/Mining,Maps/Geography,Science/Technology

Announces the availability of an online global geologic map of Mars which records the distribution of geologic units and landforms on the planet’s surface with data acquired from the Viking Orbiters. From the U.S. Geological Survey


Baseline and Projected Future Carbon Storage and Greenhouse-Gas Fluxes in Ecosystems of the Eastern United States

Categories: Climate Change,Environment,Geology/Mining,Headlines,Science/Technology

Reports that forests, wetlands, and farms in the eastern U.S. naturally store 300 million tons of carbon per year or 15% of U.S. greenhouse gas emissions each year.  Completes the national biological carbon assessment for ecosystems in the lower 48 states—a national inventory of the capacity of land and aquatic ecosystems to store or sequester carbon.  From the Geological Survey


Dissolved-Solids Sources, Loads, Yields, and Concentrations in Streams of the Conterminous United States

Categories: Environment,Geology/Mining,Natural Resources,Science/Technology

Warns about concentrations of dissolved solids, a measure of the salt content in water, which are elevated in many of U.S. streams because of human activity.  From the U.S. Geological Survey


Hurricane Sandy: Observations and Analysis of Coastal Change

Categories: Environment,Geology/Mining,Weather/Disasters

Documents the damage caused by Hurricane Sandy along the mid-Atlantic coast from North Carolina to New York.  From the U.S. Geological Survey


Earthquake Catalog for Estimation of Maximum Earthquake Magnitude, Central and Eastern United States—Part A, Prehistoric Earthquakes

Categories: Geology/Mining,Science/Technology,Weather/Disasters

Describes the construction of a global catalog of moderate to large earthquakes in order to estimate the maximum earthquake magnitude possible within a geographic region. This part discusses prehistoric earthquakes that occurred in eastern North America and Northwestern Europe.  From the U.S. Geological Survey


Platinum-Group Elements in Southern Africa: Mineral Inventory and an Assessment of Undiscovered Mineral Resources

Categories: Africa,Geology/Mining

First-ever inventory and geological assessment of the extent of known and undiscovered platinum resources.  Estimates that more than 150,000 metric tons may exist in South Africa and Zimbabwe, which produce most of the global supply for these elements which are used in jewelry and electronics.  From the U.S. Geological Survey
