Interim program for land cover mapping in Alaska utilizing Landsat digital data
The enactment of the Alaska National Interest Lands Conservation Act (ANILCA) in 1980 imposed mandates on all major land management agencies in Alaska to prepare comprehensive resource and management plans to assess wildlife habitat, oil and gas exploration and development, wild and scenic river, land disposals, timber production, and archaeological and cultural resources, To meet these objective

New horizons in remote sensing for forest and range resource management
Forest and range resource scientists were among the first to recognize the potential of aircraft and satellite remote sensing for management of timber, forage, water, and wildlife resource. Today, data from a variety of sensor systems are being put to practical use for inventorying, monitoring, and assessing forest and range resources. In the future, improved sensor systems providing new kinds o

Water quality and chemical evolution of ground water within the north coast limestone aquifers of Puerto Rico
Waters within the north coastal limestoneaquifers are suitable for public supply, industrial and agricultural uses. For the artesian aquifer and the updip parts of the watertable aquifer, calcium and bicarbonate are the dominant ionic species with total dissolved solids and chloride concentrations below 500 and 250 mg/L, respectively. In coastal areas of thewater table aquifer, where a freshwater-

Fluorine in Colorado oil shale
Oil shale from the lower part of the Eocene Green River Formation in the Piceance Creek Basin, Colorado, averages 0.13 weight percent fluorine, which is about twice that found in common shales, but is the same as the average amount found in some oil shales from other parts of the world. Some fluorine may reside in fluorapatite; however, limited data suggest that cryolite may be quantitatively more

A new isostatic residual gravity map of the conterminous United States
In order to display more clearly the gravity anomalies caused by bodies of geologic interest in the crust, a new colored isostatic residual gravity map of the conterminous United States has been prepared using the gravity data set compiled for the Gravity Anomaly Map of the United States (SEG, 1982). The isostatic residual map is based on an Airy-Heiskanen model of local compensation, with the sur
