Hydrologic data for computation of sediment discharge: Toutle and North Fork Toutle Rivers near Mount St. Helens, Washington, water years 1980-84 Hydrologic data for computation of sediment discharge: Toutle and North Fork Toutle Rivers near Mount St. Helens, Washington, water years 1980-84
Immediately after the devastating May 18, 1980, eruption of Mount St. Helens, a program was initiated by the U.S. Geological Survey to study the streamflow and sediment characteristics of streams impacted by the eruption. Some of the data gathered in that program are presented in this report. Data are presented for two key sites in the Toutle River basin: North Fork Toutle River near Kid...

Source-rock evaluation of outcrop samples from Vanuatu (Malakula, Espiritu Santo, Maewo, and Pentecost) Source-rock evaluation of outcrop samples from Vanuatu (Malakula, Espiritu Santo, Maewo, and Pentecost)
Thirty-nine outcrop samples of mudstones, siltstones, and limestones were collected for source-rock evaluation of the sedimentary column in Vanuatu. Twenty-nine samples showing the least evidence of oxidation were selected for total organic analysis from the Miocene Matanui Group and Port Sandwich Formation in Malakula, and from the Miocene Ilava, Peteao, and Pelapa Formations in...

A water-resources appraisal of the Mount Shasta area in northern California, 1985 A water-resources appraisal of the Mount Shasta area in northern California, 1985
Present Mount Shasta, California, area hydrologic characteristics were documented to compare future changes due to land use or volcanic activity. Lower flanks of Mount Shasta consist of broad aprons of pyroclastic-flow, debris flow, and fluvial deposits, with incised channels on upper parts of the mountain. Data include glacial areas and volumes, streamflow, sediment concentrations...

Geologic and hydrologic investigations of a potential nuclear waste disposal site at Yucca Mountain, southern Nevada Geologic and hydrologic investigations of a potential nuclear waste disposal site at Yucca Mountain, southern Nevada
Crustal velocity sections based on two seismic-refraction profiles are presented for the area west of Yucca Mountain, Nye County, Nevada. The Crater Flat profile is interpreted in terms of six velocity layers ranging from 1.5 to 6.1 km/s. Interpretation of the Beatty profile reveals an escarpment near the northeast edge of Bare Mountain, where Paleozoic rocks are probably down-faulted...
New trend- trigonometric model for interpolation and prediction of the geomagnetic field utilizing the new DGRF models New trend- trigonometric model for interpolation and prediction of the geomagnetic field utilizing the new DGRF models
At the IUGG Assembly at Vancouver during August 1987 new definitive geomagnetic reference field (DGRF) models to degree 10 for 1945, 1950, 1955, and 1960 were adopted by IAGA. Before these new DGRF models were accepted, the author developed a trend and trigonometric model (old trig model) based on the models IGRF 1945, IGRF 1950, IGRF 1955, IGRF 1960, DGRF 1965, DGRF 1970, DGRF 1975...
