Lakes of Oregon, Volume 4: Clackamas County
M.V. Shulters
1976, Report
An inventory of lakes and reservoirs of Oregon is essential for a complete evaluation of the total surface-water supply of the State and to provide a basis for answering questions about Oregon's lakes. Much of the information on lakes and reservoirs previously collected by Federal and State agencies has never...
Coral reef recovery in Florida and the Persian Gulf
Eugene A. Shinn
1976, Environmental Geology (1) 241-254
Long-term observations and study of coral reef destruction by hurricanes in the Florida Keys show, surprisingly, that although corals are devastated on a grand scale during storms, recovery is rapid. Recovery occurs because of the widespread scattering of live fragments, many of which become growth sites...
Steps to the moon
Water Resources Division, U.S. Geological Survey, Alvin E. Dale
1976, Report
On July 20, 1969, man walked on the surface of the Moon and began a new chapter of his studies that will eventually disclose the geologic nature of the Earth's nearest neighbor. Although he has finally reached the Moon and sampled its substance, much work and study remain before he...
National Cartographic Information Center (NCIC)
Water Resources Division, U.S. Geological Survey
1976, Report
The National Cartographic Information Center (NCIC), established by the U.S. Geological Survey, Department of the Interior, in July 1974, provides a national information service to make cartographic data of the United States more easily accessible to the public and to various Federal, State, and local agencies. At present, more than...
Access routes to the U.S. Geological Survey's EROS Data Center, Sioux Falls, South Dakota
Water Resources Division, U.S. Geological Survey
1976, Report
The EROS Data Center is a part of the Earth Resources Observation Systems (EROS) Program of the Department of the Interior, managed by the U.S. Geological Survey. It is the national center for the processing anddissemination of spacecraft and aircraft acquired photographic imagery and electronic data of the Earth's resources....
Computation of unsteady flows in rivers and estuaries by the method of characteristics
Chintu Lai, C. A. Onions
1976, Report
This report is a program documentation to the latest revision (1975) of the unsteady open-channel flow simulation model by the method of characteristics, Version 13 in the program series, which employs a multiple-reach scheme treating each subreach as a prismatic shape. A long waterway of variable cross section, properties and...
Changing energy economics: foreword
DeYoung Jr.
1976, Proceedings of the Mineral Economics Symposium, November 9, 1976, Washington, D.C.: "a challenge for the materials industry: changing energy economics" 1-2
Some characteristics of fall migration of female woodcock
R.A. Coon, P.D. Caldwell, G.L. Storm
1976, Journal of Wildlife Management (40) 91-95
Nine female woodcock (Philohela minor) were radio-tagged in central Pennsylvania before fall migration to monitor premigratory and migratory movements. Within 15 days of departure, 5 of the birds moved 0.8 to 8.0 km from their normally used area, but the remaining 4 did not move. In 1973 five marked woodcock...
A reward band study of mallards to estimate band reporting rates
Charles J. Henny, K.P. Burnham
1976, Journal of Wildlife Management (40) 1-14
Reward bands ($10) were placed on 2,122 hatching-year mallards (Anas platyrhynchos), and an additional 11,490 received conventional bands (controls) to estimate band reporting rates. An analysis of band recoveries indicated that the reporting rate was dependent primarily upon three factors: (1) the distance banded birds were recovered from the banding...
Delayed molt of primary feathers of mourning doves during winter
J.W. Ault, V.J. Heller, J. C. Lewis, J.A. Morrison
1976, Journal of Wildlife Management (40) 184-187
During a study of the ecology of mourning doves (Zenaida macroura) in Jackson County, southwestern Oklahoma, we noted (Morrison and Lewis 1974) that the post juvenal molt of primary feathers progressed at a slower rate than is described in the literature (Jenkins 1955:23, Swank 1955, Southeastern Association of Game and...
Thermal effects on fish ecology
Charles C. Coutant
1976, Book chapter, Encyclopedia of Environmental Science and Engineering
Of all the environmental factors that influence aquatic organisms, temperature is the most all-pervasive. There is always an environmental temperature while other factors may or may not be present to exert their effects. Fish are, for all practical purposes, thermal conformers, or obligate poikilotherms. That is, they are able to...
