Issues in characterizing phenology from satellite observations
B. C. Reed, J.F. Brown
2002, Conference Paper, Use of Earth Observation Data for Phenological Monitoring, Ispra, Italy, 2–13 December 2002, Proceedings
Over the past decade, many investigators have published techniques for deriving phenological parameters, especially the start of the growing season (SOS), from time-series satellite imagery. The principal satellite sensor for these studies is the advanced very high resolution radiometer (AVHRR). This study investigates the characteristics of four of the primary...

Historical trend in ice thickness on the Piscataquis River in central Maine.
Thomas G. Huntington, Robert W. Dudley, Glenn A. Hodgkins
2002, Conference Paper, Proceedings of the 59th Eastern Snow Conference, June 5-7, 2002, Stowe, VT
We analyzed a long-term record of ice thickness on the Piscataquis River in central Maine to determine whether there were temporal trends that were associated with climate warming. Trends in ice thickness were compared and correlated with regional time series of winter air temperature, heating degree days (HDD) , date of river ice-out,...
SHRIMP and Conventional UPb ages of Ordovician granites and tonalites in the central Appalachian Piedmont: Implications for Paleozoic tectonic events
John N. Aleinikoff, J. Wright Horton, Jr., Avery Ala Drake
2002, American Journal of Science (302) 50-75
Discordant Cambrian U-Pb ages of questionable reliability for metamor-phosed plutonic rocks in the central Appalachian Piedmont of northern Virginia, Maryland, and the District of Columbia have led to different regional geologic interpretations and controversies. In this study, we use the sensitive high resolution ion microprobe (SHRIMP) for dating 25-m diameter...
Evaluating the performance of a crop water balance model in estimating regional crop production
Gabriel B. Senay, James Verdin
2002, Conference Paper, ISPRS archives – Volume XXXIV part 1, 2002
The comparison between a spatially distributed crop index and reported yield was evaluated. The crop index was generated by a crop water balance model that simulates the reduction of crop yield (as a percentage of the potential) due to water deficit. This model is currently operational as a monitoring and...

Geologic information for aggregate resource planning
William H. Langer, David A. Lindsey, Daniel H. Knepper
2002, Book chapter, Deposit and geoenvironmental models for resource exploitation and environmental security
Construction and maintenance of the infrastructure is dependent on such raw materials as aggregate (crushed stone, sand, and gravel). Despite this dependence, urban expansion often works to the detriment of the production of those essential raw materials. The failure to plan for the protection and extraction of aggregate resources...
Late Miocene and early Pliocene biosiliceous sedimentation along the California margin
John A. Barron, Mitchell Lyle, Itaru Koizumi
2002, Revista Mexicana de Ciencias Geológicas (19) 161-169
Biogenic opal sedimentation is compared between offshore and onshore areas of the California margin during the late middle Miocene, the late Miocene, and the early Pliocene. The records from offshore ODP Sites 1010 and 1021 have declining opal abundance, with a dramatic three-fold decline at about 11.5 Ma and a...
Estimating the potential for submergence for two wetlands in the Mississippi River Delta
J.M. Rybczyk, Donald R. Cahoon
2002, Estuaries (25) 985-998
We used a combined field and modeling approach to estimate the potential for submergence for one rapidly deteriorating (Bayou Chitigue Marsh) and one apparently stable (Old Oyster Bayou Marsh) saltmarsh wetland in coastal Louisiana, given two eustatic sea level rise scenarios: the current rate (0.15 cm year−1); and the central...

Landslide triggers and types
Robert L. Schuster, Gerald F. Wieczoreck
2002, Conference Paper, Landslides
The term “landslide trigger” refers to an external stimulus, such as intense rainfall, rapid snowmelt, seismic shaking, volcanic eruption, stream/coastal erosion, or natural dam failure, which causes an immediate or near-immediate response in the form of landslide activity. In this paper, we discuss the types of landslides caused by these...

A fresh look at glacial floods
Steve M. Colman
2002, Science (296) 1251-1252
We tend to think of continental-scale ice sheets as rather ponderous affairs, inexorably advancing southward over the landscape and then slowly retreating to the north at the end of each ice age. Over the last 20 years, however, evidence has accumulated that this is a misconception. We now know that...
Vulnerability assessment of a port and harbor community to earthquake and tsunami hazards: Integrating technical expert and stakeholder input
Nathan J. Wood, James W. Good, Robert F. Goodwin
2002, Natural Hazards Review (3) 148-157
Research suggests that the Pacific Northwest could experience catastrophic earthquakes and tsunamis in the near future, posing a significant threat to the numerous ports and harbors along the coast. A collaborative, multiagency initiative is underway to increase the resiliency of Pacific Northwest ports and harbors to these hazards, involving Oregon...

Design and performance of limestone drains to increase pH and remove metals from acidic mine drainage, Chapter 2

2002, Book chapter, Handbook of Groundwater Remediation Using Permeable Reactive Barriers
Data on the construction characteristics and the composition of influent and effluent at 13 underground, limestone-filled drains in Pennsylvania and Maryland are reported to evaluate the design and performance of limestone drains for the attenuation of acidity and dissolved metals in acidic mine drainage. On the basis of the initial...
Synimpact-postimpact transition inside Chesapeake Bay crater
Claude (Wylie) Poag
2002, Geology (30) 995-998
The transition from synimpact to postimpact sedimentation inside Chesapeake Bay impact crater began with accumulation of fallout debris, the final synimpact deposit. Evi dence of a synimpact fallout layer at this site comes from the presence of unusual, millimeter- scale, pyrite microstructures at the top of the Exmore crater-fill breccia....
West Florida shelf circulation and temperature budget for the 1999 spring transition
Ruoying He, Robert H. Weisberg
2002, Continental Shelf Research (22) 719-748
Mid-latitude continental shelves undergo a spring transition as the net surface heat flux changes from cooling to warming. Using in situ data and a numerical circulation model we investigate the circulation and temperature budget on the West Florida Continental Shelf (WFS) for the spring transition of 1999. The model is...
