Lower to middle Eocene sequences of the New Jersey coastal plain and their significance for global climate change
James V. Browning, Kenneth G. Miller, Mickey C. Van Fossen, Chengjie Liu, Dorothy K. Pak, Marie-Pierre Aubry, Laurel M. Bybell
1997, Proceedings of the Ocean Drilling Program: Scientific Results (150X) 229-242
Boreholes from Island Beach, Allaire, Atlantic City, and Mays Landing, NJ provide an excellent chronology of lower to middle Eocene passive margin sequences and allow analysis of long-term sea-level changes and sedimentation patterns. These New Jersey sequences are tied directly to the geomagnetic polarity time scale through magnetostratigraphy. Integrated stratigraphy...
Upper Eocene sequence stratigraphy and the Absecon Inlet Formation, New Jersey Coastal Plain
James V. Browning, Kenneth G. Miller, Laurel M. Bybell
1997, Proceedings of the Ocean Drilling Program: Scientific Results (150X) 243-266
We evaluate the age, benthic biofacies, and sequence stratigraphy of thick and well-recovered upper Eocene sediments from the New Jersey Coastal Plain. These strata are herein defined as a lithostratigraphic unit and named the Absecon Inlet Formation. The formation is divided into upper and lower portions. At its type locality...
Late Paleocene and early Eocene calcareous nannofossils from three boreholes in an onshore-offshore transect from New Jersey to the Atlantic Continental Rise
Laurel M. Bybell, Jean Self-Trail
1997, Proceedings of the Ocean Drilling Program: Scientific Results (150X) 91-110
Closely spaced, upper Paleocene and lower Eocene samples from three boreholes near Clayton, NJ, at Island Beach, NJ, and at Site 605 on the Atlantic Ocean continental rise were examined for their calcareous nannofossil content. This study documents calcareous nannofossil occurrences in Zones NP9 and NP10 and identifies biostratigraphically useful...
Detection of underground voids in Ohio by use of geophysical methods
Jens Munk, R. A. Sheets
1997, Water-Resources Investigations Report 97-4221
Geophysical methods are generally classified as electrical, potential field, and seismic methods. Each method type relies on contrasts of physical properties in the subsurface. Forward models based on the physical properties of air- and water-filled voids within common geologic materials indicate that several geophysical methods are technically feasible for detection...

G. Lynn Wingard, T.M. Scott, Lucy E. Edwards, S.D. Weedman, K. R. Simmons
1997, Sedimentary Geology (108) 207-228
A very thick (> 300 m) nearly continuous Oligocene section exists in southern peninsular Florida, as revealed by lithostratigraphic, biostratigraphic (mollusks and dinocysts), chronostratigraphic (Sr isotopes) and petrographic analyses of twelve cores and two quarries. The Oligocene deposits in the subsurface of southern Florida are the thickest documented in the...
Volcano and earthquake hazards in the Crater Lake region, Oregon
Charles R. Bacon, Larry G. Mastin, Kevin M. Scott, Manuel Nathenson
1997, Open-File Report 97-487
Crater Lake lies in a basin, or caldera, formed by collapse of the Cascade volcano known as Mount Mazama during a violent, climactic eruption about 7,700 years ago. This event dramatically changed the character of the volcano so that many potential types of future events have no precedent there. This...
