The Northern Glaciated Plains in the upper Midwest United States is a region where fishing generates millions of dollars a year for local and state economies. Maintaining these revenues requires the management of fish populations that are popular and accessible (e.g. boat ramps, public land access) to anglers. Fisheries throughout the world are currently undergoing unprecedented changes to water levels and habitat quality resulting from climate change. The consequences of climate change to Northern Glaciated Plains fisheries are unknown but pose an immediate challenge for resource managers as angler access and opportunities can be jeopardized when: a) boat ramps become inaccessible due to changing water levels,...

The over-all objective of the program was to determine, by laboratory experiments, the kinetics and the mechanics of the various reactions which produce acid in coal mine drainage. Secondary objectives included identification of the role of bacterial catalysts, evaluation of methods to inhibit pyrite weathering, and laboratory application of a new method of weathering inhibition.

In its role of providing technical assistance to the mining industry, the Bureau of Mines' Tuscaloosa Research Center has conducted research to develop trapped miner location systems which would aid in locating miners trapped by underground mining disasters. Efforts to produce electromagnetic systems for the location of trapped miners underground and to communicate with them were surveyed, from the 1920's to 1981. Theoretical studies of through- the -earth electromagnetic transmissions are described as well as studies of the electrical characteristics of various rocks, minerals, and soil. Several trapped miner location systems are reviewed including the Westinghouse systems, the DEVELCO system, and an automated...

The Northern Prairie Wildlife Research Center (NPWRC) conducts integrated research to fulfill the Department of the Interior’s responsibilities to the Nation’s natural resources. Located on 600 acres along the James River Valley near Jamestown, North Dakota, the NPWRC develops and disseminates scientific information needed to understand, conserve, and wisely manage the Nation’s biological resources. Research emphasis is primarily on midcontinental plant and animal species and ecosystems of the United States.
The Juneau Gold Belt portion of the Juneau Mining District has historically had the greatest mining and exploration activity within the district and is the subject of this report. Between 1880 and 1983, the mines within the Juneau Gold Belt produced 6.7 million oz gold, 3.1 million oz silver, and 45 million lbs lead, all of which had a total value of about $157,000,000. Information in this report is based on an extensive literature search which included unpublished private company reports, U.S. Geological Survey, State of Alaska, and Bureau reports, personal interviews, and Bureau field work. The field work during 1985 revealed the locations of numerous adits, shafts and other old mine workings, many of which were...
