Michael Schoenberg
1998, Water-Resources Investigations Report 97-4084
Declining hydraulic heads in the Buffalo and Wahpeton aquifers are of concern to the Minnesota Department of Natural Resources and local water managers because of limited groundwater resources in the southern part of the Red River of the North drainage basin. The U.S. Geological Survey, in cooperation with the Minnesota...

In 1996, seven cores were recovered in western Collier County, southwestern Florida, to acquire subsurface geologic and hydrologic data to support ground-water modeling efforts. This report presents the lithostratigraphy, X-ray diffraction analyses, petrography, biostratigraphy, and strontium-isotope stratigraphy of these cores. The oldest unit encountered in the study cores is an...
Geology of the Black Mingo Group (Paleocene) in the Kingstree and St. Stephen areas of South Carolina
Robert E. Weems, Laurel M. Bybell
1998, Transactions of the American Philosophical Society (88) 9-27
Paleocene vertebrate remains from the areas of Kingstree and St. Stephen, South Carolina, come from the Rhems and Williamsburg formations of the Black Mingo Group. Sedimentary textures and fossils indicate that both units accumulated in shallow, nearshore marine, lagoonal, and deltaic depositional environments. Calcareous nannofossils and dinoflagellates indicate that the...
Loose-coupling a cellular automaton model and GIS: Long-term urban growth prediction for San Francisco and Washington/Baltimore
Keith Clarke, Leonard Gaydos
1998, International Journal of Geographical Information Science (12) 699-714
Prior research developed a cellular automaton model, that was calibrated by using historical digital maps of urban areas and can be used to predict the future extent of an urban area. The model has now been applied to two rapidly growing, but remarkably different urban areas: the San Francisco Bay...

Remagnetization of Cretaceous forearc strata on Santa Margarita and Magdalena Islands, Baja California Sur: Implications for northward transport along the California margin
Jonathan T. Hagstrum, R.L. Sedlock
1998, Tectonics (17) 872-882
Paleomagnetic data for two sections of Cretaceous forearc strata with different structural attitudes on Santa Margarita and Magdalena Islands in Baja California Sur, Mexico, indicate that these rocks have been remagnetized, probably during the late Cenozoic. The in situ paleomagnetic directions, however, are similar to data from other Cretaceous rocks...

James L. Bischoff, editor(s)
1998, Open-File Report 98-132
Owens Lake, located at the eastern base of the central Sierra Nevada (Fig. 1), was the terminus of the Owens River prior to the lake's complete desiccation shortly after 1913 due to river diversion by the City of Los Angeles. During earlier wetter cycles, the lake overflowed to fill a...
