Ground-water levels in Arkansas, spring 1982
Joe Edds
1982, Open-File Report 82-852
The report contains about 640 ground-water level measurements made in observation wells in Arkansas in the spring of 1982. In addition, the report contains potentiometric-surface maps and well hydrographs relating to the alluvial aquifer and the Sparta Sand, the most important aquifers with respect to ground-water availability and use in...
High-resolution seismic-reflection profiles and sidescan-sonar records collected on Block Island Sound by U.S. Geological Survey, R/V ASTERIAS, cruise AST 81-2
S. W. Needell, R. S. Lewis
1982, Open-File Report 82-322
Cruise AST 81-2 was conducted aboard the R/V ASTERIAS during September 10-18, 1981, in Block Island Sound by the U.S. Geological Survey. It was funded in part by the Connecticut Geological and Natural History Survey. The purpose of the study was to define and map the geology and shallow structure,...
Habitat Suitability Index Models: Green sunfish
Robert J. Stuber, Glen Gebhart, O. Eugene Maughan
1982, FWS/OBS 82/10.15
This is one of a series of publications that provide information on the habitat requirements of selected fish and wildlife species. Literature describing the relationship between habitat variables related to life requisites and habitat suitability for the Green sunfish (Lepomis cyanellus) are synthesized. These data are subsequently used to develop...
Habitat Suitability Index models: White crappie
Elizabeth A. Edwards, Douglas A. Krieger, Glen Gebhart, O. Eugene Maughan
1982, FWS/OBS 82/10.7
The white crappie (Pomoxis annularis) is native to freshwater lakes and streams from the southern Great Lakes, west to Nebraska, south to Texas and Alabama, east to North Carolina, then west of the Appalachian Mountains to New York. It has been widely introduced outside this range throughout North America (Hubbs...
Habitat Suitability Index Models: Northern pike
Peter D. Inskip
1982, FWS/OBS 82/10.17
The habitat use information and Habitat Suitability Index (HSI) models presented in this document are intended for use in impact assessment and habitat management activities. Literature concerning the habitat requirements and preferences of northern pike is reviewed and then synthesized into HSI models, which are scaled to produce an index...
Water resources data, Pennsylvania, water year 1981. Volume 3: Ohio River and St. Lawrence River basins
Water Resources Division, U.S. Geological Survey
1982, Water Data Report PA-81-3
Water resources data for the 1981 water year for Pennsylvania consist of records of discharge and water quality of streams; elevation and contents of lakes and reservoirs; and water levels of ground-water wells. This volume contains records for water discharge at 86 gaging stations; elevations and contents at 3 lakes...
Habitat suitability index models: Cutthroat trout
Terry J. Hickman, Robert F. Raleigh
1982, FWS/OBS 82/10.5
Cutthroat trout, Salmo clarki, are a polytypic species consisting of several geographically distinct forms with a broad distribution and a great amount of genetic diversity (Hickman 1978; Behnke 1979). Behnke (1979) recognized 13 extant subspecies: Coastal cutthroat (S. c. clarki) in coastal streams from Prince William Sound, Alaska to the...
Preliminary geomagnetic data, College Observatory, Fairbanks, Alaska: October 1982
John B. Townshend, J.E. Papp, E.A. Sauter, L.Y. Torrence, T.K. Cunningham
1982, Open-File Report 82-300-J
The preliminary geomagnetic data included here is made available to scientific personnel and organizations, as part of a cooperative effort and on a data exchange basis because of the early need by some users. To avoid delay, all of the data is copied from original forms processed at the observatory;...
Aeromagnetic measurements in the Cascade Range and Modoc Plateau of northern California; report on work done from June 1, 1980, to November 30, 1980
Richard Couch, Michael Gemperle
1982, Open-File Report 82-932
Aeromagnetic measurements made along flightlines oriented east- west and spaced at 1.6-km intervals and along lines oriented north- south and spaced at 8-km intervals, over approximately 30,000 square km of northern California, exhibit crossing errors of less than 5 nanoTeslas. The measurements show short-wavelength magnetic anomalies associated with near-surface volcanics over and...
Use of flumes in metering discharge at gaging stations
F. A. Kilpatrick, V.R. Schneider
1982, Open-File Report 82-871
Flumes for metering discharge are usually of two general types--critical-flow flumes and supercritical-flow flumes. In this report the principles underlying the design of each are discussed, the most commonly used flumes of each of the two types are described, and discharge ratings for each are presented. Considerations in choosing and...
A generic guide to the larvae of the Nearctic Tanytarsini, (Chironomidae:diptera)
J.W. Steiner, J.S. Doughman, C.R. Moore
1982, Open-File Report 82-768
Larvae of the tribe Tanytarsini occur in nearly every aquatic habitat in North America where they act as primary consumers in the food chain. This new taxonomic guide overcomes some deficiencies in existing keys to this tribe and the reviewed and updated taxonomy enables identification of the larvae that may...
Water-level maps of the alluvial aquifer, northwestern Mississippi, September 1981
Daphne Darden
1982, Open-File Report 82-574
The study area, locally known as "the Delta", covers the Mississippi River Alluvial Plain in northwestern Mississippi. The Delta is a nearly flat southward sloping surface characterized by oxbow lakes, abandoned stram channels, natural levees, backswamp areas, and bayous.The accompanying maps were prepared to show the effects of ground-water withdrawal...
