Oculina Bank: Sidescan sonar and sediment data from a deep-water coral reef habitat off east-central Florida
Kathryn M. Scanlon, Peter R. Briere, Christopher C. Koenig
1999, Open-File Report 99-10
The Experimental Oculina Research Reserve (EORR) is located along the shelf edge off east-central Florida in water depths of about 60 to 100 meters. It is about 7.5 km wide and 43 km long and encompasses numerous high-relief rocky pinnacles where Oculina varicosa, a fragile deep-water coral, grows. These coral...
Digital geologic map database of the Payette National Forest and vicinity, Idaho
Karen Lund, P. D. Derkey, T. R. Brandt, J.R. Oblad
1999, Open-File Report 98-219-B
The geology of the Payette National Forest and vicinity, Idaho (Fig. 1), was mapped and compiled by Karen Lund between 1992 and 1996. The geologic data for the digital map are from original mapping as well as compilation by Lund of numerous sources of published and unpublished geologic maps that...
Documentation for HYDMOD; a program for extracting and processing time-series data from the U.S. Geological Survey's modular three-dimensional finite-difference ground-water flow model
Randall T. Hanson, Stanley A. Leake
1999, Open-File Report 98-564
This report presents a FORTRAN computer program that generates simulated time-series data as output from the U.S. Geological Survey Modular Finite-Difference Ground-Water Flow Model at user-specified point locations or a collection of points that compose a profile through the modeled region. The program can save time-series data at user-specified locations...
An interpretation of the 1997 airborne electromagnetic (AEM) survey, Fort Huachuca vicinity, Cochise County, Arizona
Mark W. Bultman, Mark E. Gettings, Jeff Wynn
1999, Open-File Report 99-7-B
In March of 1997, an airborne electromagnetic (AEM) survey of the Fort Huachuca Military Reservation and immediate surrounds was conducted. This survey was sponsored by the U.S. Army and contracted through the Geologic Division of the U.S. Geological Survey (USGS). Data were gathered by Geoterrex-Dighem Ltd. of Ottawa, Canada. The...
Map showing the potential for mineral deposits associated with Precambrian mafic and ultramafic rocks in the Blacktail and Henrys Lake Mountains and the Greenhorn and Ruby Ranges of southwestern Montana
Jane M. Hammarstrom, Bradley S. Van Gosen, Robert R. Carlson, Dolores M. Kulik
1999, Open-File Report 98-224-D
In response to requests from the Bureau of Land Management (BLM) and the U.S. Forest Service (USFS), the U.S. Geological Survey (USGS) conducted a mineral resource assessment in the Dillon BLM Resource Area in Beaverhead and Madison Counties, southwestern Montana. These agencies use mineral resource data in creating and updating...
Vegetative resistance to flow in South Florida: Summary of vegetation sampling at sites NESRS3 and P33, Shark River Slough, April 1996
Virginia Carter, Henry A. Ruhl, Nancy B. Rybicki, Justin T. Reel, Patricia T. Gammon
1999, Open-File Report 99-187
The U.S. Geological Survey is one of many agencies participating in the effort to restore the south Florida Everglades. We are sampling and characterizing the vegetation at selected sites in the Everglades as part of a study to quantify vegetative flow resistance. The objectives of the vegetative sampling are (1)...
Vegetative resistance to flow in south Florida: Summary of vegetation sampling at sites NESRS3 and P33, Shark River Slough, November, 1996
Virginia Carter, Justin T. Reel, Nancy B. Rybicki, Henry A. Ruhl, Patricia T. Gammon, Jonathan K. Lee
1999, Open-File Report 99-218
The U.S. Geological Survey is one of many agencies participating in the effort to restore the South Florida Everglades. We are sampling and characterizing the vegetation at selected sites in the Everglades as part of a study to quantify vegetative flow resistance. The objectives of the vegetation sampling are (1)...
Biomass and vegetative characteristics of sawgrass grown in a tilting flume as part of a study of vegetative resistance to flow
Nancy B. Rybicki, Justin T. Reel, Henry A. Ruhl, Patricia T. Gammon, Virginia Carter, Jonathan K. Lee
1999, Open-File Report 99-230
The U.S. Geological Survey is studying vegetative resistance to flow in the south Florida Everglades as part of a multidisciplinary effort to restore the South Florida Ecosystem. In order to test the flow resistance of sawgrass, one of the dominant species in the Everglades, uniform, dense stands of sawgrass were...
Results of time-domain electromagnetic soundings in Everglades National Park, Florida
D.V. Fitterman, Maria Deszcz-Pan, C.E. Stoddard
1999, Open-File Report 99-426
This report describes the collection, processing, and interpretation of time-domain electromagnetic soundings from Everglades National Park. The results are used to locate the extent of seawater intrusion in the Biscayne aquifer and to map the base of the Biscayne aquifer in regions where well coverage is sparse. The data show...
Rock, stream sediment, and heavy-mineral concentrate geochemical data from Unga and western Popof Islands, Alaska Peninsula, Alaska: Chapter 6 in A geological and geophysical study of the gold-silver vein system of Unga Island, Southwestern Alaska
Frederic H. Wilson, Stan E. Church, Elizabeth Bailey
1999, Open-File Report 99-136-6
The data reported here was collected during the 1982-1988 mineral resource assessment of the Port Moller and adjacent quadrangles (see Wilson and others, 1996). Analytical data for virtually all of the samples reported here has been previously published in a series of U.S.G.S. Open-File reports, including Angeloni and others (1985),...
Carboniferous and older carbonate rocks: Lithofacies, extent, and reservoir quality: Chapter CC in The oil and gas resource potential of the Arctic National Wildlife Refuge 1002 area, Alaska
Julie A. Dumoulin
1999, Open-File Report 98-34-CC
Carboniferous and older carbonate rocks are potential hydrocarbon reservoir facies for four plays in the 1002 area of the Arctic National Wildlife Refuge. These rocks include several units in the pre-Carboniferous basement and the Carboniferous Lisburne Group. Data from exploratory wells west of the 1002 area, outcrops south of the...
Geology of Unga Island and the northwestern part of Popof Island: Chapter 2 in A geological and geophysical study of the gold-silver vein system of Unga Island, Southwestern Alaska

1999, Open-File Report 99-136-2
The first geologic map of Unga Island was published by Atwood (1911; scale 1:250,000), who correctly inferred the middle Tertiary age of the volcanic rocks and made the important distinction between the lava flows and the intrusive domes. Although Burk's (1964) reconnaissance map of the Alaska Peninsula (scale 1:250,000) has...
