Mid-range sidescan-sonar images covering parts of proposed tracts for OCS lease sale 56 and contiguous areas, Manteo, Cape Fear, and adjacent quadrangles off North Carolina
Peter Popenoe, K. V. Cashman, Dale Chayes, William B. F. Ryan
1981, Open-File Report 81-554
The U.S. Geological Survey (USGS), in cooperation with the U.S. Bureau of Land Management (BLM) and the Lamont-Doherty Geological Observatory (LDGO), collected 335 km of mid-range sidescan-sonar data in some of the tracts proposed for inclusion in Federal OCS (Outer Continental Shelf) Oil and Gas Lease Sale 56 and in...
Preliminary appraisal of the hydrology of the Blocker area, Pittsburg County, Oklahoma
Melvin V. Marcher, D. L. Bergman, J.D. Stoner, S. P. Blumer
1981, Open-File Report 81-1187
Bedrock in the Blocker area of southeastern Oklahoma consists principally of shale, siltstone, and sandstone of the Boggy and Savanna Formations of Pennsylvanian age. These rocks have been folded to form the Panther Mountain syncline on the south and the Kinta anticline on the north. Alluvium along streams is less...
Preliminary metallogenic map of North America: An alphabetical listing of deposits
Philip White Guild
1981, Circular 858-B
The names of 4,215 ore deposits shown on the Preliminary Metallogenic Map of North America are listed in alphabetical order by country, and by subdivisions of the larger countries (Canada, Mexico, and the United States). Map numbers, major and minor constituents, geographic coordinates, and a geologic code are given for...
Quality assurance practices for the chemical and biological analyses of water and fluvial sediments
Linda C. Friedman, David E. Erdman
1981, Open-File Report 81-650
This chapter contains practices used by the U.S. Geological Survey to assure the quality of analytical data for water, fluvial sediment, and aquatic organisms.These practices are directed primarily toward personnel making water-quality measurements. Some detail specific quality control techniques, others document quality assurance procedures being used by the Central Laboratories...
Probable high ground-water levels in Massachusetts
M. H. Frimpter
1981, Open-File Report 80-1205
Water-level records from an observation-well network are analyzed for utility in estimating probable high ground-water levels in three different geohydrologic environments in Massachusetts. Analyses were made of 83 observation wells with between 8 and 37 years of records. Maximum annual water levels occur most frequently in March and April. The...
Hydrologic effects of highway-deicing chemicals in Massachusetts
L.R. Frost Jr., S.J. Pollock, R.F. Wakelee
1981, Open-File Report 81-209
Methods of estimating annual mean and annual maximum chloride concentrations and sodium concentrations in streams were developed using multiple and simple linear regression techniques and data collected during the 1972-77 water years. Independent variables are easily obtainable parameters such as total salt application within a basin, annual precipitation, and drainage...
Hydrologic effects of highway-deicing chemicals in Massachusetts; executive summary
L.R. Frost Jr., S.J. Pollock, R.F. Wakelee
1981, Open-File Report 81-210
Methods of estimating annual mean and annual maximum chloride concentrations in streams were developed through multiple and simple linear regression techniques using data collected during the 1972-77 water years. Independent variables are easily obtainable parameters, such as total salt application within a basin, annual precipitation, and drainage basin characteristics. Methods...
