210Pb balance and implications for particle transport on the continental shelf, U.S. Middle Atlantic Bight 210Pb balance and implications for particle transport on the continental shelf, U.S. Middle Atlantic Bight
Supply of 210Pb to the continental shelf off the northeastern United States is dominated by the deposition from the atmosphere, the rate of which is reliably known from previously published work. Excess 210Pb inventories in the shelf sediments show accumulations that are nearly in balance with the supply, even in areas of relict sands where it is believed that no net accumulation of...

A compilation of sulfur dioxide and carbon dioxide emission-rate data from Mount St. Helens during 1980-88 A compilation of sulfur dioxide and carbon dioxide emission-rate data from Mount St. Helens during 1980-88
Airborne monitoring of Mount St. Helens by the USGS began inMay 1980 for sulfur dioxide emissions and in July 1980 forcarbon dioxide emissions. A correlation spectrometer, orCOSPEC, was used to measure sulfur dioxide in Mount St.Helens' plume. The upward-looking COSPEC was mounted in afixed-wing aircraft and flown below and at right angles to theplume. Typically, three to six traverses...

Tapping the Earth's natural heat Tapping the Earth's natural heat
T he Earth is a bountiful source of heat. It continuously produces heat at depth, primarily by the decay of naturally radioactive chemical elements (principally uranium, thorium, and potassium) that occur in small amounts in all rocks. This deep heat then rises toward the cooler surface, where scientists can measure the rate of its escape through the Earth's crust. The annual heat loss...

Quaternary tectonics of Utah with emphasis on earthquake-hazard characterization Quaternary tectonics of Utah with emphasis on earthquake-hazard characterization
This report consolidates and synthesizes information on Quaternary faulting, folding, and volcanism in Utah and characterizes recent tectonic activity throughout the state. The primary purpose is to provide a comprehensive reference on faultspecific seismic sources and surface rupture to facilitate the evaluation of earthquake hazards in Utah. Two 1:500,000-scale maps show Quaternary...
