Evidence of cold climate slope processes from the New Jersey Coastal Plain: Debris flow stratigraphy at Haines Corner, Camden County, New Jersey
Wayne L. Newell
2005, Open-File Report 2005-1296
Excavations through surficial deposits across the New Jersey Coastal Plain commonly reveal homogenized surficial sediments, deformed sedimentary structures, chaotically rearranged bed-forms, and wedge-shaped cracks filled with sand from the top-most layers of extant soil profiles. As a whole, these abundant, broadly distributed phenomena are best explained as artifacts of...
Charting color from the eye of the beholder
Edward Landa, Mark Fairchild
2005, American Scientist (93) 436-436
Everyone knows the particular shade of yellow that adorns all school buses across the United States. But how do we define exactly what shade this is, and reproduce the same color from coast to coast? Much of the standardization of colors stems from the century-old work of Alfred Munsell, who...

Kim H. Haag, Terrie M. Lee, Donald C. Herndon
2005, Scientific Investigations Report 2005-5109
Wetland bathymetry and vegetation mapping are two commonly used lines of evidence for assessing the hydrologic and ecologic status of expansive coastal and riverine wetlands. For small isolated freshwater wetlands, however, bathymetric data coupled with vegetation assessments are generally scarce, despite the prevalence of isolated wetlands in many regions of...
Antipodal hotspots and bipolar catastrophes: Were oceanic large-body impacts the cause?
Jonathan T. Hagstrum
2005, Earth and Planetary Science Letters (236) 13-27
One aspect of the hotspot distribution that has received little attention is its antipodal character. Of 45 ‘primary’ hotspots found in most hotspot compilations 22 (49%) form antipodal pairs within observed hotspot drift limits (≤ 20 mm/yr). In addition, the available ages, or possible age ranges, for both hotspots of an...

Correlated declines in Pacific arctic snow and sea ice cover
Robert P. Stone, David C. Douglas, Gennady I. Belchansky, Sheldon Drobot
2005, Arctic Research of the United States (19) 18-25
Simulations of future climate suggest that global warming will reduce Arctic snow and ice cover, resulting in decreased surface albedo (reflectivity). Lowering of the surface albedo leads to further warming by increasing solar absorption at the surface. This phenomenon is referred to as “temperature–albedo feedback.” Anticipation of such a feedback...
