L.M. Bybell, Self-Trail J.M.
1994, Professional Paper 1554
Calcareous nannofossils of late Paleocene and early Eocene age were examined from six coreholes located in southern New Jersey. Fossil data indicate that four of these coreholes (GL 913, GL 915, GL 917, and the Clayton Core) contain an apparently continuous depositional sequence across the Paleocene-Eocene boundary. There are four...

1994, Open-File Report 92-139
The dunes and the wetlands along the southern shore of Lake Michigan are underlain by a complex aquifer system composed of unconsolidated glacial, lacustrine, and eolian deposits. Surficial dune, beach, and glacial lacustrine sands compose an extensive surficial aquifer. The underlying drift contains three major confined sand aquifers. Potentiometric...

Charles D. Masters
1994, Open-File Report 94-556
The following publications were prepared in the course of World Energy Studies by program scientists. Most are open-file reports because we consider it our prime responsibility to get the program supporting data into the public record. Various of the authors have also seen fit to publish their work in...
Effects of ground-water chemistry and flow on quality of drainflow in the western San Joaquin Valley, California
John L. Fio, David A. Leighton
1994, Open-File Report 94-72
Chemical and geohydrologic data were used to assess the effects of regional ground-water flow on the quality of on-farm drainflows in a part of the western San Joaquin Valley, California. Shallow ground water beneath farm fields has been enriched in stable isotopes and salts by partial evaporation from the shallow...
