Undiscovered oil and gas resources and leasing status of forestlands in Wyoming Undiscovered oil and gas resources and leasing status of forestlands in Wyoming
All of four national forests, one national grassland, and parts of four additional forests lie within the State of Wyoming. Some of these National Forest System lands have moderate to high potential for undiscovered oil and gas resources. In the 1989 National Assessment of undiscovered oil and gas and in various Open-File Reports, the U.S. Geological Survey described oil and gas plays...

Use of mesocosm data to predict effects in aquatic ecosystems: Limits to interpretation: Chapter 16 Use of mesocosm data to predict effects in aquatic ecosystems: Limits to interpretation: Chapter 16
Aquatic mesocosm studies are being used to refute a presumption of risk derived from laboratory toxicity tests conducted under the Federal Insecticide, Fungicide, and Rodenticide Act (FIFRA). Mesocosm studies incorporate many biological, chemical and physical characteristics of natural ecosystems. Hence, they serve as realistic surrogates of natural ecosystems and allow tests of...

Regional evaluations of acid deposition effects on forests: Eastern spruce-fir Regional evaluations of acid deposition effects on forests: Eastern spruce-fir
Having reviewed the results of the Integrated Forest Study (IFS) project, we now try to place the results in a larger perspective by very briefly summarizing acid deposition effects and their potential role in forest health in the several forest types represented in the IFS project. This chapter gives brief overviews of the situation in eastern spruce-fir, eastern hardwood, and southern...

Gravity modelling across the Transantarctic Mountains, Northern Victoria Land Gravity modelling across the Transantarctic Mountains, Northern Victoria Land
During GANOVEX V and GANOVEX VI, new gravity data were collected in northern Victoria Land. The GANOVEX V data cover the Mt. Melbourne 1:250.000 quadrangle, while the GANOVEX VI data Transantarctic Mountains south of the Drygalski Ice Tongue. The two data sets are connected by a coastal traverse. The measurements were constrained by satellite-positioned elevation (GPS) data and, in some...
