Modified Mercalli intensities for some California north-coast earthquakes
W. H. Bakun
1999, Open-File Report 99-171
Modified Mercalli Intensity (MMI) data are used by Bakun (in preparation) to estimate the location and moment magnitude M of California north-coast earthquakes from MMI observations only. The MMI data and site corrections used by Bakun (in preparation) are listed in this Open-file Report. This report is also accessible at...
Open Skies aerial photography of selected areas in Central America affected by Hurricane Mitch
Bruce Molnia, Cheryl A. Hallam
1999, Circular 1181
Between October 27 and November 1, 1998, Central America was devastated by Hurricane Mitch. Following a humanitarian relief effort, one of the first informational needs was complete aerial photographic coverage of the storm ravaged areas so that the governments of the affected countries, the U.S. agencies planning to provide assistance,...
Extensometer, water-level, and lithologic data from Bacon and Bethel Islands in Sacramento-San Joaquin Delta, California, September 1987 to August 1993
Barry D. Kerr, David A. Leighton
1999, Open-File Report 98-631
Compaction, water-level, and lithologic data were collected at extensometer sites on Bacon and Bethel Islands, anchored at 436 and 536 feet below land surface, respectively. The data reported here are part of a study of the processes causing subsidence in the Sacramento?San Joaquin Delta. The depths were selected to ensure...
Water-quality assessment of the eastern Iowa basins: Data, September 1995 through September 1996
Kimberlee K.B. Akers, Douglas J. Schnoebelen, Mark E. Savoca, Linda R. Roberts, Kent Becher
1999, Open-File Report 99-66
The U.S. Geological Survey began data-collection activities in the Eastern Iowa Basins study unit of the National Water-Quality Assessment Program in September 1995 with the purpose of determining the status and trends in water quality. Surface-water data were collected, beginning in March 1996, on a monthly basis with occasional extra...
Water-quality and lake-stage data for Wisconsin lakes, water year 1998
Dale M. Robertson, J. F. Elder, H.S. Garn, G. L. Goddard, S.B. Marsh, D.L. Olson, W. J. Rose
1999, Open-File Report 99-98
The U.S. Geological Survey (USGS), in cooperation with local and other agencies, collects data at selected lakes throughout Wisconsin. These data, accumulated over many years, provide a data base for developing an improved understanding of the water quality of lakes. To make these data available to interested parties outside the...
Water-quality assessment of the Delmarva Peninsula, Delaware, Maryland, and Virginia: Results of investigations, 1987-91
Robert J. Shedlock, J. M. Denver, M. A. Hayes, P. A. Hamilton, M.T. Koterba, L. J. Bachman, P. J. Phillips, W. S. Banks
1999, Water Supply Paper 2355-A
A regional ground-water-quality assessment of the Delmarva Peninsula was conducted as a pilot study for the U.S. Geological Survey's National Water-Quality Assessment (NAWQA) Program. The study focused on the surficial aquifer and used both existing data and new data collected between 1988 and 1991. The new water samples were analyzed...
Turbidite pathways in Cascadia Basin and Tufts abyssal plain, Part A, Astoria Channel, Blanco Valley, and Gorda Basin
Stephen C. Wolf, Michael R. Hamer
1999, Open-File Report 99-157
This open-file report was prepared in support of the USGS Earthquake Hazards of Cascadia Project. The primary objective of this phase of the project is to determine recurrence intervals of turbidites in Cascadia basin-floor channel systems and evaluate implications of this event record for the paleoseismic history of the Cascadia...

Sustainability of ground-water resources
William M. Alley, Thomas E. Reilly, O. Lehn Franke
1999, Circular 1186
The pumpage of fresh ground water in the United States in 1995 was estimated to be approximately 77 billion gallons per day (Solley and others, 1998), which is about 8 percent of the estimated 1 trillion gallons per day of natural recharge to the Nation's ground-water systems (Nace, 1960). From...
Sustainable growth in America's heartland: 3-D geologic maps as the foundation
Central Great Lakes Geologic Mapping Coalition, Illinois State Geological Survey, Indiana Geological Survey, Michigan Geological Survey Division, Ohio Division of Geological Survey, Water Resources Division, U.S. Geological Survey
1999, Circular 1190
The Central Great Lakes States of Illinois, Indiana, Michigan, and Ohio constitute one of the most productive and economically important regions in the country—America’s heartland. The agriculture, industry, business, recreation, and ecology of these States are based on a common geologic heritage. During the last 1.8 million years, glaciers repeatedly...
Last interglacial sea-surface temperature estimates from the California margin; improvements to the modern analog technique
Harry J. Dowsett, Richard Z. Poore
1999, Bulletin 2171
Total faunal analyses of planktic foraminifer assemblages are used to derive sea surface temperature estimates for the last interglacial from Ocean Drilling Program Sites 1018 and 1020 off northern and central California. Foraminifer assemblage data were transformed to sea-surface temperature (SST) estimates by using the modern analog technique (MAT). In...
Deep Aquifer Remediation Tools (DARTs): A new technology for ground-water remediation
David L. Naftz, James A. Davis III
1999, Fact Sheet 156-99
Potable ground-water supplies throughout the world are contaminated or threatened by advancing plumes containing radionuclides, metals, and organic compounds. Currently (1999), the most widely used method of ground-water remediation is a combination of extraction, ex-situ treatment, and discharge of the treated water, commonly known as pump and treat. Pump-and-treat methods...
The Washington and Oregon mid-shelf silt deposit and its relation to the late Holocene Columbia River sediment budget
Stephen C. Wolf, Hans Nelson, Michael R. Hamer, Gita Dunhill, R. Lawrence Phillips
1999, Open-File Report 99-173
The purpose of this report is to compile and analyze existing data which lend support to the development of a sediment budget for the Columbia River, coastal, and offshore regions of southwest Washington. This will contribute to the construction of a sediment budget model which will reflect sediment sources, depocenters,...
