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...

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...

The significance of observations at active volcanoes; A review and annotated bibliography of studies at Kilauea and Mount St. Helens The significance of observations at active volcanoes; A review and annotated bibliography of studies at Kilauea and Mount St. Helens
Study of active volcanoes yields information of much broader significance than to only the discipline of volcanology. Some applications are 1) interpretation of lava-flow structures, stratigraphic complexities, and petrologic relations in older volcanic units; 2) interpretation of bulk properties of the mantle and constraints on partial melting and deep magma transport; 3) interpretation...

Geomorphic and hydrologic dynamics of zero-order basins Geomorphic and hydrologic dynamics of zero-order basins
The 1987 International Symposium on Erosion and Sedimentation in the Pacific Rim, held August 3–7, 1987, in Corvallis, Oreg., included a special session on the geomorphic and hydrologic dynamics of zero-order drainage basins. “Zero-order basin” is one of several terms used to describe unchanneled swales or hollows that may occupy considerable areas of higher-order drainage basins. These...

Hawaii Volcano Observatory 75th anniversary Hawaii Volcano Observatory 75th anniversary
The 75th anniversary of the founding of the U.S. Geological Survey (USGS) Hawaiian Volcano Observatory (HVO) was celebrated during January 1987. The festivities began on January 9 with the opening in Hilo of a major exhibit at the Wailoa Center on the current work of HVO, its history, and its special relationship to Hawaii Volcanoes National Park. In addition to spectacular photographs...

Eocene siliceous and calcareous phytoplankton, Deep Sea Drilling Project Leg 95 Eocene siliceous and calcareous phytoplankton, Deep Sea Drilling Project Leg 95
Eocene siliceous and calcareous phytoplankton, with emphasis on silicoflagellates, were studied in 62 samples from DSDP Sites 612 and 613 on the continental slope and rise off New Jersey. The mid-latitude assemblages correlate well with assemblages from California, Peru, and offshore of southern Brazil, but are distinctly different from high-latitude cold-water assemblages of the...

North Atlantic Quaternary silicoflagellates, Deep Sea Drilling Project Leg 94 North Atlantic Quaternary silicoflagellates, Deep Sea Drilling Project Leg 94
Quaternary silicoflagellates from Deep Sea Drilling Project (DSDP) Mid-Atlantic Leg 94 are generally sparse and dissolution-thinned. Mesocena quadrangula, a low-latitude biostratigraphic guide species, occurs at all four sites studied (606, 607, 609, and 611), allowing identification of low-latitude zones—Dictyocha aculeata Zone, Mesocena quadrangula Zone, and Dictyocha stapedia stapedia...
