Breeding ground survey methods in North America
W.F. Crissey
1970, Book chapter, International Regional Meeting on Conservation of Wildfowl Resources (Europe, Western Asia, Northern and Tropical Africa). Proceedings, Leningrad, USSR, 25-30 September, 1968
DDE and DDD residues correlated with mortality of experimental birds
William H. Stickel, Lucille F. Stickel, Francis B. Coon
William B. Deichmann, Rafael A. Penalver, Jack L. Radomski, editor(s)
1970, Conference Paper, Pesticides symposia: Collection of papers presented at the 6th -7th Inter-American Conferences on Toxicology and Occupational Medicine, University of Miami School of Medicine, Miami
Nearly everywhere in nature are found DDE and DDD, which are metabolites of DDT, and they often become concentrated through food chains. DDD is also a commercial insecticide. large amounts of both are frequently found in birds, but the significance of these amounts has puzzled many owrkers. Studies at Clear...
The thin eggshell problem
L.F. Stickel, L.I. Rhodes
J.W. Gillett, editor(s)
1970, Book chapter, Proceedings of the symposium, the biological impact of pesticides in the environment
It has long been known that DDT and related chemicals can impair the reproduction of birds. In early years of organochlorine pesticide use, widespread mortality occurred immediately following heavy applications of these chemicals, and survivors contained substantial amounts of toxicant in their tissues. Repopulation from untreated areas tended...
A proposed streamflow data program for Ohio
Peter W. Anttila
1970, Open-File Report 70-10
A streamflow data program is proposed for Ohio which consists of both data collection and data analysis. The program is proposed after a study which (1) established long-term objectives and goals for streamflow information, (2) examined and analyzed available data to determine its adequacy for meeting the established goals, and...
Buldir Depression - A Late Tertiary graben on the Aleutian Ridge, Alaska
M. S. Marlow, D.W. Scholl, E. C. Buffington, R.E. Boyce, T. R. Alpha, P.J. Smith, C.J. Shipek
1970, Marine Geology (8) 85-108
Buldir Depression is a large, rectilinear basin that lies on the northern edge of the Aleutian Ridge and is aligned with the arcuate chain of active volcanoes on the ridge crest. The depression appears to be a volcanic-tectonic feature, which began to form...
Earthquakes induced by fluid injection and explosion
J. H. Healy, R. M. Hamilton, C.B. Raleigh
1970, Tectonophysics (9) 205-214
Earthquakes generated by fluid injection near Denver, Colorado, are compared with earthquakes triggered by nuclear explosion at the Nevada Test Site. Spatial distributions of the earthquakes in both cases are compatible with the hypothesis that variation of fluid pressure in preexisting fractures controls...
Rapid changes in the head of the Rio Balsas Submarine Canyon system, Mexico
E. Reimnitz, M. Gutierrez-Estrada
1970, Marine Geology (8) 245-258
The investigation of a river delta and the heads of several nearby submarine canyons in western Mexico produced evidence for rapid changes in the configuration and depth of the nearshore portions of canyon tributaries. General scarcity of data on the rates of submarine...
Development of the Astoria Canyon-Fan physiography and comparison with similar systems
C.H. Nelson, P.R. Carlson, J.V. Byrne, T. R. Alpha
1970, Marine Geology (8) 259-291
A detailed bathymetric study of Astoria Canyon and Astoria Fan provides a model for typical submarine canyon-fan systems. The present canyon head is 9 miles (17 km) west of the Columbia River mouth but buried Pleistocene channels appear to have connected the two features in the past. The canyon, which...
The structure and origin of the large submarine canyons of the Bering Sea
D.W. Scholl, E. C. Buffington, D.M. Hopkins, T. R. Alpha
1970, Marine Geology (8) 187-210
Three exceptionally large and long submarine canyons — Bering, Pribilof, and Zhemchug — incise the continental slope underlying the southeastern Bering Sea. Bering Canyon, the world's longest known slope valley, is approximately 400 km long and has a volume of 4,300 km3. The volume of Pribilof Canyon is 1,300 km3 and...
The mechanics of stick-slip
J.D. Byerlee
1970, Tectonophysics (9) 475-486
Physical mechanisms that have been proposed to explain the occurrence of stick-slip motion during frictional sliding have been examined in the light of results obtained from experiments with rocks and brittle minerals. An instability caused by sudden brittle fracture of locked regions on...
Submarine basalt from the Revillagigedo Islands region, Mexico
J.G. Moore
1970, Marine Geology (9) 331-345
Ocean-floor dredging and submarine photography in the Revillagigedo region off the west coast of Mexico reveal that the dominant exposed rock of the submarine part of the large island-forming volcanoes (Roca Partida and San Benedicto) is a uniform alkali pillow basalt; more siliceous rocks are exposed on the upper, subaerial...
Water resources data for Idaho, water year 1969: Part 1. Surface water records
U.S. Geological Survey
1970, Water Data Report ID-69-1
Surface-water records for the 1969 water year for gaging stations, partial-record stations, and miscellaneous sites within the State of Idaho are given in this report and their locations shown in figures 2 and 3. Records for a few selected gaging stations in bordering States also are included. The records were...
Geology of the Bushrod Island-New Georgia clay deposit near Monrovia, Liberia
Lawrence Vernon Blade
1970, Open-File Report 70-29
The Bushrod Island-New Georgia clay deposit near Monrovia, Liberia, consisted of interlensing clay and very fine to fine quartz sand; it was deposited in elongate subparallel troughs that had been eroded in coarse-grained sediments. The troughs are interpreted as abandoned stream channels on a former delta of the St. Paul...
Hydrology of the Upper Malad River basin, southeastern Idaho
Edward J. Pluhowski
1970, Water Supply Paper 1888
The report area comprises 485 square miles in the Basin and Range physiographic province. It includes most of eastern' Oneida County and parts of Franklin, Bannock, and Power Counties of southeastern Idaho. Relief is about 5,000 feet; the floor of the Malad Valley is at an average altitude of about...
