The following report provides information for the public good about the origin, quality, and quantity of mineral resources world-wide. This Bulletin reports progress on some of the current activities of the Office of Mineral Resources and reflects the necessity for an international perspective regarding mineral resources and research technology.
From objectives and scope of work: The objective of this report is to provide a comprehensive review of the biology and population status of sea turtles potentially subject to entanglement in North Pacific high-seas driftnet fisheries. The report will assist National Marine Fisheries Service efforts to assess the impacts of the driftnet fisheries on threatened and endangered sea turtle populations.
From abstract: This report describes Cambrian through Mississippian rocks in the Powder River Basin representing five depositional sequences that reflect both the biological evolution and the tectonic development of western North America.
A report which examines the sedimentary rocks deposited along a segment of the west coast of the interior seaway of North America in southwest Wyoming during the late Santonian and early Campanian subages of the Late Cretaceous Epoch.
A report that discusses the interpretation of impact shock evidence found in the K-T boundary sections and discusses the constraints imposed by the Australasian tektites and microtektites on the role of the 180-km Chicxulub crater in mass extinction.
Abstract: The Hawaii pelagic surface fisheries and more recently the longline fisheries have grown dramatically. As a result, competition between fisheries on the fishing grounds and in the marketplace has also increased. Physical conflicts between vessels and claims of decreased fishing success by surface (troll and handline) fishermen led to the enactment of Federal regulations limiting the number of domestic longline vessels and the areas in which they can operate. The scientific evidence of biological or economic fishery interaction between longline and small-vessel fishermen is limited but suggests that intense longline fishing near the Hawaiian Islands has the potential to affect catch rates in other Hawaii fisheries. Better data collection and more research are needed to document fishery interaction and to improve fishery management.
This report presents data collected from the observational studies on Hawaiian monk seals and green turtles at Pearl and Hermes Reef in the Northwestern Hawaiian Islands. The data presented was taken on 9-8 of June 1990 and 1 August to 13 September 1991. The data collected was limited to objectives conducting atoll-wide seal censuses, resighting tagged seals, tagging weaned pups, and surveying and destroying debris capable of entangling wildlife. Additionally, efforts in 1991 included retagging seals, tagging unknown-age seals, weighing and measuring immature seals, and bleach-marking seals for ID purposes. Also, interatoll movement, survival, injuries, and entanglement of seals were monitored, seal scats and spews were collected, turtles were tagged, and previously tagged turtles were resighted.
This report presents the results of observational studies on the Hawaiian monk seal at French Frigate Shoals in the Northwestern Hawaiian Islands from April 4 to September 11 1985, and during 2-19 of December. The data recorded is on the population structure, reproduction, and factors affecting survival.
This report is based on an observational study on the Hawaiian monk seal at Laysan Island, Northwestern Hawaiian Islands, from May 4 to August 4 1986. Data includes population rates, reproductive rates, deaths, injuries, necropsies, and entanglements.
The following document is a report on an observational study around the Hawaiian monk seal on Lisianski Island in Northwestern Hawaiian Islands between 16-18 of May to 29th of August and the 10th of June to the 11th of August 1990. The data collected is based around reproduction and factors affecting survival as well ashaul-out patterns and population structure.
A report which describes the hydrothermal alteration of numerous outcrop samples collected in the vicinity of Mount Hood, as well as drill cuttings from 13 of the geothermal drill holes for which we were able to obtain sample splits.
From Abstract: This report describes the kinematics of the Aspen Grove landslide of Ephraim Canyon in central Utah that moved during the spring and summer months of 1983-86.
A paper about thermal activity in Yellowstone National Park. It assesses impacts of geothermal, oil, gas, and other types of development adjacent to the park. It also relates these changes to magma under the park.
From Abstract: "During the next 5 years investigators examined a number of factors that have a bearing upon miners' ability to put on and use the apparatus in an emergency: the procedure being taught; availability and utilization of training models; opportunities to practice; hygiene; and on-the-job-training. This report presents an overview of that research."
From abstract: This report is a study on the history of sedimentology and deposition of the lower Paleocene Tullock Member of the Fort Union Formation, Powder River Basin, Wyoming and Montana while looking at the geometry and sedimentary structures.
From abstract: Information in this report supplements the geologic map of the Stanford Canyon quadrangle that provides chemical data, thin sections, and hand specimens for each of the samples collected in the quadrangle.
Abstract: Statistical guidelines are described for the development of a pilot scientific observer sampling program to collect turtle interactions data from the Hawaii longline fishery. The best available data are presented and potential sources of variability in longline turtle take rates are discussed. A stratified sampling design for a pilot survey is developed based on time and target species. An array of sample size choices for the pilot program is presented covering a range of tolerance levels and confidence levels for estimation of total turtle take.
From introduction: The investigation described herein is a part of the USGS Evolution of Sedimentary Basins Program. This report concerns the Pennsylvanian and Permian stratigraphic framework, structural development, and paleogeography of the San Juan Basin.
From abstract: This report describes the North Horn Formation in the eastern part of the San Pitch Mountains of Utah was deposited in nonmarine environments that included alluvial fans, varied fluvial and overbank settings, and lacustrine settings.
From abstract: A study of mean random vitrinite reflectance of surface and near-surface samples was conducted in western Colorado and eastern Utah in order to better understand the subsidence and thermal histories of the Laramide-age Uinta and Piceance basins and to estimate the the thickness of overburden removed from the two basins. The history of uplift on some of the adjacent Laramide uplifts were also studied.
Proceedings of a workshop held in February 1990 called "Tertiary Stratigraphy of Highly Extended Terranes, Southern Basin and Range" at the Desert Research Center of the California State University System, Soda Springs, near Baker, California. This volume is a collection of stratigraphic data and interpretation.
