"This report describes the methods, analyses, results, and conclusions of two different aging studies."

Tables detailing aging tallies produced as part of the aging failure survey. The tables display the detailed breakdown for the data by component, system effect, failure category, and age of component at the time of failure. (p. E-3 of report).

The following report summarizes the locations, resources, and petrophysical data of known bitumen-bearing deposits located primarily in Alabama, California, Kentucky, Texas, and Utah.

From Summary: These studies document the temporally episodic and areally site-specific character of subaerial erosion, which is shown to be directly related to prevailing meteorologic conditions.

From abstract: This report describes a study of coastal processes along the Atlantic Coast from Sea Bright to Ocean Township, New Jersey. Predictive tools were developed and a data analysis made to assist in evaluation and implementation of comprehensive shore protection plans for this highly utilized stretch of coastline.

A paper about modal and major-element chemical data on the Mesozoic plutonic rocks of the Cowtrack Mountain and Glass Mountain quadrangles are presented in tables, maps, and diagrams.

This report summarizes the catch rate of the Heterocarpus laevigatus from the most productive shipping vessel in Hawaii, 1984, the Mokihana. The statistics provide a fairly comprehensive geographic survey of the relative abundance of the species along the Hawaiian Archipelago.

This is a report that examines the economic and operational performance of lobster fishing vessels in the Northwestern Hawaiian Islands.

The following report analyzes the geomorphic setting, the use of seismic-refraction data to delineate buried deposits, and the geotechnical analysis of aggregate samples of the sand and gravel deposits in Sheridan, Wyoming.

This is a report on the observational study of the green turtle and monk seal population in the Pearl and Hermes Reef, 1986. No entanglements, injuries, or deaths were observed.

This is a report on the observational study of the Hawaiian monk seal and the green turtle on Lisianski Island during the summers of 1984 and 1985. The purpose of this study is to monitor and aid the recovery of both endangered species.

This is a report where the Hawaiian monk seal and the green turtle were studied intermittently on Lisianski Island throughout the summer of 1986. This observational study includes injuries, deaths, reproductions, entanglements and tagging of seals and green turtles.

This is a report on the observational studies of the Hawaiian monk seal and green turtle on Lisianski Island in the Northwestern Hawaiian Islands. These studies were taken during the 1-4 of June and 5-29 or August 1987 and focused on haul out, reproduction, and factors affecting survival.

This is a report based on the the findings of an observational study over the monk seals on the Kure Atoll. The studies take place between January 30 to October 23, 1985. There's a focus on pups they took captive before release, and by chance there are reports of two tagged green turtles.

Report issued by the Bureau of Mines over studies conducted on the outbursts of salt often responsible for fatalities in salt mines. The salt samples were tested for methane content. The test results are discussed. This report includes tables, maps, illustrations, and photographs.

From abstract: Mafic and ultramafic xenoliths in the Western United States are present in volcanic rocks ranging from lamprophyric to dacitic in composition and are found in every major tectonic province from the Coast ranges from California to the Great Plains. Xenoliths from 68 localities are described here, but new localities are being discovered, and much remain to be learned about their distribution with respect to the tectonic and geophysical framework of the Western United States.

This report follows mineral-resource surveys taken at Barbours Creek and Shawvers Run Wilderness study areas in Craig County, Virginia. This report provides the findings of these studies, mineral deposits primarily.

Abstract: The Behind the Rocks Wilderness Study Area (UT-060-140A) consists of 12,635 acres in Grand and San Juan Counties, Utah. The study area has inferred subeconomic resources of potash and halite in the subsurface, and sandstone on the surface. The study area has high potential for undiscovered resources of oil and gas, low potential for undiscovered uranium, copper, vanadium, gold, silver, other metals, and geothermal energy, and unknown potential for the rare-earth mineral, braitschite. There is no resource potential for potash or halite (beyond the previously mentioned inferred resources) or for coal.

From abstract: At the request of the U.S. Bureau of Land Management, approximately 84,165 acres of the Clover Mountains Wilderness Study Area (NV-050-139) was evaluated for mineral resources (known) and mineral resource potential (undiscovered). In this report, the area studied is referred to as "the wilderness study area" or simply "the study area;" any reference to the Clover Mountains Wilderness Study Area refers only to that part of the wilderness study area for which a mineral survey was requested by the U.S. Bureau of Land Management. The study area is located in southern Nevada, in Lincoln County, about 90 mi northeast of Las Vegas. No identified mineral resources exist inside the study area, although gold, silver, and copper resources are found immediately to the west at the Pennsylvania mine.

From abstract: During the present study, all working were examined and representative rock and mineral samples from them were analyzed. Reconnaissance geochemical sampling of rocks, minerals, and stream sediments was conducted for the entire area.

From introduction: This report presents an evaluation of the mineral endowment (identified resources (known) and mineral resource potential (undiscovered)) of the study area and is the product of several separate studies by the USBM and the USGS.

From abstract: This report includes field investigations to evaluate the mineral resource potential of the Sweetwater Canyon Wilderness Study Area that were conducted during the summer of 1986.

From abstract: At the request of the U.S. Bureau of Land Management, approximately 105,200 acres of the Turtle Mountains Wilderness Study Area (CDCA-307) were evaluated for mineral resources (known) and resource potential (undiscovered). In this report, the area studied is referred to as "the wilderness study area" or simply "the study area"; any reference to the Turtle Mountain Wilderness Study Area refers only to that part of the wilderness study area for which a mineral survey was requested by the U.S. Bureau of Land Management. The wilderness study area is in southeastern San Bernardino County, Calif. Gold, silver, copper, and lead have been mined within and adjacent to the study area.
