Evaluation of size-distribution effects and laboratory precision in the analysis of bottom materials
Bottom materials may be useful in evaluating areal and temporal changes in concentrations of certain chemical constituents in the overlying waters. They are particularly useful for detecting hydrophobic compounds that may be present in the stream waters at low concentrations or at intermittent intervals. The particle-size distribution in the bottom materials must be considered when areal or tempor

Colorado Plateau
Field studies in the Colorado Plateau occupy an honored place in the development of geomorphic theory. The purpose of this chapter is to briefly review the foundational, regional, and process-oriented studies in the region, and to provide a review of promising threads of inquiry set in a context of more than a century of geomorphologic research in the region.The Colorado Plateau has sharply define

Recording and processing procedures for multi-channel seismic-reflection data collected in the western Ross Sea, Antarctica
During 1984, over 2300 km of multichannel seismic-reflection data were recorded by the U.S. Geological Survey in the western Ross Sea and Iselin Bank regions. A temporary loss and sinking of the streamer led to increasing the streamer tow depth to 20 m, which resulted in some attenuation of frequencies in the 30-50 Hz range but no significant difference in resolution of the stacked data. Severe

Rocky Mountains
The Rocky Mountain region is one of the most topographically distinct and impressive parts of North America. The Rocky Mountains rise abruptly above the bordering regions, particularly on the east and northeast where they are flanked by plains, less so on the west and southwest where they are bounded by high plateaus. The Rocky Mountains comprise more than 100 individually named ranges that form a

Post-fire demography of resprout and seedling establishment by Adenostoma fasciculatum in the California chaparral
Adenostoma fasciculatum (chamise) forms the dominant element of chaparral ecosystems in California. This evergreen, ericoid-leaved shrub occurs as a codominant in mixed chaparral or an overwhelming dominant in chamise chaparral, being present in over 70% of the chaparral stands in the state (Hanes 1971). No other chaparral shrub approaches A. fasciculatum in community importance. Unlike the majori
