Carbonate aquifers provide water of acceptable quality for human use and consumption in the majority of wells sampled across the U.S. according to a recent U.S. Geological Survey (USGS) study. With few exceptions, chemicals detected in groundwater from carbonate aquifers were low, generally below human-health benchmarks.
Tracking Native Mussels on the Mississippi River
For the first time ever, mussels in the Mississippi River will be radio tagged and their movements observed during the water-level drawdown that is scheduled to begin next week.
A new tool provides land managers with a predictive model for mapping the potential distribution of desert tortoise habitat and to evaluate different land-use issues the tortoises face at a landscape scale.
The entire listed range of the federally threatened Mojave population of desert tortoise (Gopherus agassizii) is covered by this habitat model.
A new report by the USGS provides information that improves the understanding of the water resources of the upper Humboldt River basin. The study, conducted in cooperation with Elko County, describes the hydrogeologic framework that controls the movement of ground-water in the upper Humboldt River basin.
Detailed searches of planetary images are now available through a new Web-based tool created by USGS Astrogeology Science Center web-developers, scientists, and cartographers. The tool, which is funded by NASA's Planetary Data System, is being unveiled to the public this week.
Getting a picture of the status of conservation efforts in the United States has just been made easier thanks to a just-released database that allows wildlife and conservation professionals to visit a single place to find comprehensive information on protected areas.
The U.S. Geological Survey has updated its assessment of in-place oil shale resources in the Piceance Basin in western Colorado.
Development of oil shale has significant technological and environmental challenges and no economic extraction method is currently available in the U.S. Therefore it is unknown how much of the assessed in-place (total amount present) resource is recoverable.
Each of the 818 large watersheds in the Mississippi/Atchafalaya River Basin (MARB) has been ranked on the basis of SPARROW model estimates of nitrogen and phosphorus yields delivered to the Gulf of Mexico by the U.S. Geological Survey (USGS), in cooperation with the U.S. Environmental Protection Agency (EPA).
The U.S. Geological Survey (USGS) will award up to $7 million in grants and cooperative agreements for earthquake research in 2010.
Interested researchers can apply online at GRANTS.GOV under the funding opportunity number 10HQPA0001. Applications are due May 13, 2009.
Data for Fourth Quarter of 2008
The U.S. Geological Survey's latest quarterly data on U.S. mineral commodity production reflect the overall decline in the U.S. economy and the domestic housing market.
U.S. production of construction materials declined significantly in the fourth quarter of 2008 as compared with the third quarter of 2008.
The largest waterbird congregation site in the Indian subcontinent is the site of a new international study of migratory birds and their role in the spread of highly pathogenic avian influenza (HPAI) H5N1.
Strong First Half Followed by Slump in Final Months
The value of U.S. nonfuel mine production rose to $71 billion in 2008, a 2.4 percent increase from that of 2007, according to preliminary estimates by the USGS. Deteriorating economic conditions, however, resulted in a downward trend for minerals consumption at yearend 2008.
