C. Wylie Poag
2004, Geotimes (49) 22-25
In July 1983, the shipboard scientists of Deep Sea Drilling Project Leg 95 found an unexpected bonus in a core taken 150 kilometers east of Atlantic City, N.J. At Site 612, the scientists recovered a 10-centimeter-thick layer of late Eocene debris ejected from an impact about 36 million years ago....
Coal facies studies in the eastern United States
J.C. Hower, C.F. Eble
2004, International Journal of Coal Geology (58) 3-22
Coals in the eastern United States (east of the Mississippi River) have been the subject of a number of coal facies studies, going back to the 19th century. Such studies would not necessarily fall within a strict modern classification of coal facies studies, but if a study encompassed some aspects...
Interseismic strain and rotation rates in the northeast Mojave domain, eastern California
J.C. Savage, J. L. Svarc, II W. Prescott
2004, Journal of Geophysical Research B: Solid Earth (109)
The northeast Mojave domain, a type locality for bookshelf faulting, is a region of east striking, left-lateral faults in the northeast corner of the Mojave block, a block otherwise dominated by ∼N40°W striking, right-lateral faults. Paleomagnetic evidence suggests that blocks within the domain have rotated clockwise about a vertical axis...

J.G. Moore, D.A. Clague
2004, Geological Society of America Bulletin (116) 337-347
Black manganese-iron oxide crusts form on most exposed rock on the ocean floor. Such crusts are well developed on the steep lava slopes of the Hawaiian Ridge and have been sampled during dredging and submersible dives. The crusts also occur on fragments detached from bedrock...
Origin of the Blue Ridge escarpment along the passive margin of Eastern North America
J.A. Spotila, G.C. Bank, P.W. Reiners, C. W. Naeser, N. D. Naeser, B.S. Henika
2004, Basin Research (16) 41-63
The Blue Ridge escarpment is a rugged landform situated within the ancient Appalachian orogen. While similar in some respects to the great escarpments along other passive margins, which have evolved by erosion following rifting, its youthful topographic expression has inspired proposals of Cenozoic tectonic rejuvenation in eastern North America. To...

This report identifies and characterizes candidate ground-water flow zones in the upper part of the shallow, eogenetic karst limestone of the Biscayne aquifer in the Lake Belt area of north-central Miami-Dade County using cyclostratigraphy, ground-penetrating radar (GPR), borehole geophysical logs, and continuously drilled cores. About 60 miles of GPR profiles...
Quality and sources of ground water used for public supply in Salt Lake Valley, Salt Lake County, Utah, 2001
Susan A. Thiros, Andrew H. Manning
2004, Water-Resources Investigations Report 2003-4325
Ground water supplies about one-third of the water used by the public in Salt Lake Valley, Utah. The occurrence and distribution of natural and anthropogenic compounds in ground water used for public supply in the valley were evaluated. Water samples were collected from 31 public-supply wells in 2001 and analyzed...

Spring hunting changes the regional movements of migrating greater snow geese
A. Bechet, J.-F. Giroux, G. Gauthier, J.D. Nichols, J.E. Hines
2003, Journal of Applied Ecology (40) 553-564
1. Human-induced disturbance such as hunting may influence the migratory behaviour of long-distance migrants. In 1999 and 2000 a spring hunt of greater snow geese Anser caerulescens atlanticus occurred for the first time in North America since 1916, aimed at stopping population growth to protect natural habitats. 2. We evaluated the impact of this hunt on the staging movements of geese along...

2003, Book chapter, Handbook of ecotoxicology, second edition
For the past decade, there has been growing concern about worldwide declines in amphibian populations,1,2 and a general phenomenon of declining populations was recognized in the mid-1990's. Subsequent research has validated this concern.3,4 These population declines have been defined either as decreases in numbers of individuals in an area or,...

2003, Water-Resources Investigations Report 2002-4221
Irondequoit Creek drains 169 square miles in the eastern part of Monroe County. Over time, nutrients transported by Irondequoit Creek to Irondequoit Bay on Lake Ontario have contributed to the eutrophication of the bay. Sewage-treatment-plant effluent, a major source of nutrients to the creek and its tributaries, was eliminated from...
