The role of the USFWS geographic information system in coastal decisionmaking
Unprecedented demand on coastal resources in the 1980's has generated a need for valid information and analyses to support wise management of the coastal zone. The National Coastal Ecosystems Team of the U.S. Fish and Wildlife Service recently implemented a geographic information system to enhance its ability to analyze and display environmental information about the coastal zone. Outputs from thi

Chemical immobilization of North American mule deer
The choice of agents for chemical immobilization of mule deer (Odocoileus hemionus) is a problem with a simple and effective solution, in my opinion. I recommend combinations of etorphine hydrochloride (M199©) and xylazine hydrochloride (Rompun©) administered intravenously and reversed intravenously. I have used this combination on hundreds of mule deer and have supervised its use on hundreds more

CHEMICAL STRUCTURES IN COAL: GEOCHEMICAL EVIDENCE FOR THE PRESENCE OF MIXED STRUCTURAL COMPONENTS.
The purpose of this paper is to summarize work on the chemical structural components of coal, comparing them with their possible plant precursors in modern peat. Solid-state **1**3C nuclear magnetic resonance (NMR), infrared spectroscopy (IR), elemental analysis and, in some cases, individual compound analyses formed the bases for these comparisons.

CONTRIBUTION OF LAND USE DATA TO THE INVESTIGATION OF TRENDS IN FLOODING IN THE TUG FORK BASIN OF KENTUCKY, VIRGINIA, AND WEST VIRGINIA.
The U. S. Geological Survey, in cooperation with the U. S. Bureau of Mines and the Office of Surface Mining Reclamation and Enforcement, is investigating effects of mining on flood frequency and magnitude within the basin. Changing land use, particularly the acceleration of surface mining, may cause or contribute to flooding problems.

COORDINATION OF DIGITAL CARTOGRAPHY IN THE FEDERAL GOVERNMENT.
The development and application of digital cartographic data bases are significant and important activities in the Federal Government. Increasingly, digital spatial data are being used for computer-based analyses in support of management decisions on land, forests, minerals, and energy.

DETERMINATION OF MODE OF OCCURRENCE OF TRACE ELEMENTS IN THE UPPER FREEPORT COAL BED USING SIZE AND DENSITY SEPARATION PROCEDURES.
A procedure has been developed using low temperature ashing, followed by size and sink-float separation of the ash, X-ray diffraction analysis, and instrumental neutron activation analysis to give both qualitative and quantitative information for major, minor and trace minerals and their associated trace elements in coal.

DIGITAL CARTOGRAPHY AIDS IN THE SOLUTION OF BOUNDARY DISPUTE.
The boundary between the States of Ohio and Kentucky and Indiana and Kentucky has been in dispute for many years. A major breakthrough in this continuing dispute has been a recent agreement between the States to accept the boundary line as depicted on U. S. Geological Survey 7. 5-minute quadrangle maps. A new segment of the boundary line was established utilizing the shoreline depicted on the 1966

DIGITAL GEOLOGIC MAP OF THE UNITED STATES.
The geologic map of the United States was published in 1974 by the U. S. Geological Survey. This major publication contains an enormous amount of information on the surficial geology of the United States. Many geologists have used this map as a research tool. Most have needed information from only specific parts of the map, and have manually extracted data from these areas. These data have then be

Eastern Devonian shales: Organic geochemical studies, past and present
The Eastern Devonian shales are represented by a sequence of sediments extending from New York state, south to the northern regions of Georgia and Alabama, and west into Ohio and to the Michigan and Ilinois Basins. Correlatives are known in Texas. The shale is regionally known by a number of names: Chattanooga, Dunkirk, Rhinestreet, Huron, Antrim, Ohio, Woodford, etc. These shales, other than thos
