Interactions of mercury with dissolved organic carbon in the Florida Everglades
George R. Aiken, Michael M. Reddy
1996, Fact Sheet 186-96
There has been increased awareness by both public and scientific communities over mercury contamination of game fish in South Florida. Effective management strategies for dealing with this problem will require a more thorough understanding of the factors and processes that result in the generation and transport of mercury, and control...
South Florida Ecosystem Program database development
J.A. Stapleton, Roy Sonenshein, Bob Halley
1996, Fact Sheet 174-96
Purpose  The South Florida Ecosystem Restoration Program is an intergovernmental effort to reestablish and maintain the ecosystem of south Florida. One element of the restoration effort is the development of a firm scientific basis for resource decision making. The U.S. Geological Survey (USGS) is one of the agencies that provides...
South Florida Ecosystem Program web site
Water Resources Division, U.S. Geological Survey
1996, Fact Sheet 155-96
Introduction  The South Florida Ecosystem Restoration Program is an intergovernmental effort, involving a number of agencies, to reestablish and maintain the ecosystem of south Florida. One element of the restoration effort is the development of a firm scientific basis for resource decision making. The U.S. Geological Survey (USGS), one of...
Borehole geophysical logging for water-resources investigations in Pennsylvania
Randall W. Conger
1996, Fact Sheet 218-95
Borehole geophysical logging is a procedure to collect and transmit specific information about the geologic formations penetrated by a well by raising and lowering a set of probes or sondes that contain water-tight instruments in the well. The data collected can be used to determine general formation geology, fracture distribution,...
South Florida High-accuracy elevation data collection project
Water Resources Division, U.S. Geological Survey
1996, Fact Sheet 162-96
BackgroundThe major issues facing ecosystem restoration and management in south Florida are centered on the availability and distribution of clean, fresh water. Surface water flow modeling studies are an important aspect of the scientific information needs of the ecosystem restoration initiative. Hydrologic models provide much needed predictive capabilities for evaluating...
Water flows and nutrient loads to the southwest coast of Florida—A study
Victor A. Levesque
1996, Fact Sheet 179-96
BackgroundThe embayments and estuaries of Florida's southwest coast are an integral part of the south Florida ecosystem. Nutrients and other constituents are transported to these coastal waters by surface water and ground-water flow from the Everglades National Park (ENP) and the Big Cypress Preserve and by longshore and offshore tidal...
Invisible CO2 gas killing trees at Mammoth Mountain, California
Michael L. Sorey, Christopher D. Farrar, William C. Evans, David P. Hill, Roy A. Bailey, James W. Hendley II, Peter H. Stauffer
1996, Fact Sheet 172-96
Since 1980, scientists have monitored geologic unrest in Long Valley Caldera and at adjacent Mammoth Mountain, California. After a persistent swarm of earthquakes beneath Mammoth Mountain in 1989, earth scientists discovered that large volumes of carbon dioxide (CO2) gas were seeping from beneath this volcano. This gas is killing trees...
U. S. Geological Survey programs in Pennsylvania
Water Resources Division, U.S. Geological Survey
1996, Fact Sheet 038-96
The U.S. Geological Survey (USGS) is involved in mapping and studying land, mineral, biological, and water resources and determining the risk from earthquakes and other natural hazards, which are of importance to the citizens of Pennsylvania. This Fact Sheet describes how the USGS is addressing some of the major environmental...
January 1996 floods deliver large loads of nutrients and sediment to the Chesapeake Bay
Linda D. Zynjuk, Brenda Feit Majedi
1996, Fact Sheet 140-96
The Blizzard of 1996 struck the Mid-Atlantic region in January, depositing a record amount of snowfall. Within two weeks of the paralyzing blizzard, warm and extremely humid air entered the region, followed by a major rainstorm. The combination of warm, humid air and heavy rainfall melted the snow at an unprecedented rate....
Assessing the coal resources of the United States
Harold J. Gluskoter, R. M. Flores, J. Hatch, M.A. Kirschbaum, L.F. Ruppert, Peter D. Warwick
1996, Fact Sheet 157-96
In 1994, coal production in the United States reached the highest level in history (slightly more than 909 million metric tons or one billion short tons), continuing the upward trend of coal production and utilization that began 34 years ago. Previous assessments of the coal resources of the United States,...
