USGS leads United States effort in Mallik Well
2002, Fire in the Ice: NETL Methane Hydrate Newsletter (2) 3-4
This winter, in the extremely cold, far reaches of the upper Northwest Territory of Canada, there is an international consortium of researchers participating in a program to study methane hydrates. The researchers are currently drilling a 1200 m-deep production research well through the permafrost. It is one of three wells...
Predation by Oregon spotted frogs (Rana pretiosa) on Western toads (Bufo boreas) in Oregon, USA
Christopher A. Pearl, M.P. Hayes
2002, American Midland Naturalist (147) 145-152
Toads of the genus Bufo co-occur with true frogs (family Ranidae) throughout their North American ranges. Yet, Bufo are rarely reported as prey for ranid frogs, perhaps due to dermal toxins that afford them protection from some predators. We report field observations from four different localities demonstrating that Oregon spotted...

Charles E. Barker, Peter D. Warwick, Robert J. Scott, J.M. Klein, R.W. Hook
2002, Conference Paper, AAPG Annual Meeting
In 2001, The Exploration Company (TXCO), San Antonio, announced the Sacatosa Coalbed Methane (CBM) Field in Maverick County. This field is the first CBM field in Texas (Fig. 1). The field is producing from bituminous coal in the Cretaceous Olmos Formation that outcrops to the west and dips easterly towards...

The proximal part of the giant submarine Wailau landslide, Molokai, Hawaii
D.A. Clague, J.G. Moore
2002, Journal of Volcanology and Geothermal Research (113) 259-287
The main break-in-slope on the northern submarine flank of Molokai at -1500 to -1250 m is a shoreline feature that has been only modestly modified by the Wailau landslide. Submarine canyons above the break-in-slope, including one meandering stream, were subaerially carved. Where such canyons cross the break-in-slope, plunge pools may...
System analysis to estimate subsurface flow: From global level to the State of Minnesota
B.A. Shmagin, R. Kanivetsky
2002, Environmental Geology (42) 259-269
Stream runoff data globally and in the state of Minnesota were used to estimate subsurface water flow. This system approach is based, in principal, on unity of groundwater and surface water systems, and it is in stark contrast to the traditional deterministic approach based on modeling. In coordination with methodology...

2002, Biological Science Report 2002-0001-2
Documenting the distribution of land-cover types on the Arctic National Wildlife Refuge coastal plain is the foundation for impact assessment and mitigation of potential oil exploration and development. Vegetation maps facilitate wildlife studies by allowing biologists to quantify the availability of important wildlife habitats, investigate the relationships between animal locations...
Statistical characteristics of xenoliths in the Antioch kimberlite pipe, Marshall County, northeastern Kansas
S. Kotov, Pieter Berendsen
2002, Natural Resources Research (11) 289-297
Geometrical characteristics of xenoliths in the Antioch kimberlite pipe have been considered in statistical terms. A method of conversion of 2D intersections to 3D dimensions was used. It has been shown that the Rosin-Rammler distribution of mass leads to the Weibull distribution of sizes, whereas a fractal distribution of sizes...
Introduction

2002, Biological Science Report 2002-0001-1
The Arctic National Wildlife Refuge in northeastern Alaska is one of 16 refuges in Alaska and 539 refuges nationwide within the National Wildlife Refuge System administered by the U.S. Fish and Wildlife Service. First established as the Arctic National Wildlife Range in 1960 by Public Land Order 2214, it initially...

2002, Biological Science Report 2002-0001-3
Documentation of the natural range of variation in ecological, life history, and physiological characteristics of caribou (Rangifer tarandus) of the Porcupine caribou herd is a necessary base for detecting or predicting any potential effects of industrial development on the performance (e.g., distribution, demography, weight-gain of individuals) of the herd. To...
Muskoxen

2002, Biological Science Report 2002-0001-7
Muskoxen (Ovibos moschatus) disappeared from Alaska in the late 1800s, but returned to the Arctic National Wildlife Refuge when animals were reestablished into areas of former range in 1969-1970 (Klein 1988). Released at Barter Island (Kaktovik) and the Kavik River, muskoxen initially moved into regions that encompassed the 1002 Area...
Population genetic structure in Lahontan cutthroat trout
Jennifer L. Nielsen, George K. Sage
2002, Transactions of the American Fisheries Society (131) 376-388
We used 10 microsatellite loci to examine the genetic population structure of cutthroat trout Oncorhynchus clarki within the Lahontan Basin complex. Genetic diversity was analyzed for trout from Nevada, California, and Utah representing three putative subspecies: Lahontan O. c. henshawi, Paiute O. c. seleniris, and Humboldt (an unnamed subspecies) cutthroat...

SHE analysis for biozonation of benthic foraminiferal assemblages from western arctic ocean
Lisa E. Osterman, Martin A Buzas, Lee-Ann C. Hayek
2002, Palaios (17) 297-303
Benthic foraminiferal species abundance in samples from three Mendeleyev Ridge box cores were analyzed by cluster analysis and the newer method of SHE analysis. Previously, the latter technique only has been used on foraminiferal data from depth transects of modern surface sediment samples. Unlike most methods, which initially compare all...
Field evidence for a protistan role in an organically-contaminated aquifer

2002, Environmental Science & Technology (36) 4312-4318
The association between protists, bacteria, and dissolved organic carbon (DOC) in an oxygen-depleted, 6 km-long wastewater contaminant plume within a sandy aquifer (Cape Cod, MA) was investigated by comparing abundance patterns along longitudinal and vertical transects and at a control site. Strong linear correlations were observed between unattached bacterial abundance...

Ontogenetic behavior and migration of Chinese sturgeon, Acipenser sinensis
P. Zhuang, B. Kynard, L. Zhang, T. Zhang, W. Cao
2002, Environmental Biology of Fishes (65) 83-97
The Chinese sturgeon, Acipenser sinensis, is an anadromous protected species that presently only spawns in the Yangtze River. Using laboratory experiments, we examined the behavioral preference of young Chinese sturgeon to physical habitat (water depth, illumination intensity, substrate color, and cover) and monitored their downstream migration. Hatchling free embryos were photopositive,...
Thermal conductivity measurements in porous mixtures of methane hydrate and quartz sand
W.F. Waite, B.J. deMartin, S. H. Kirby, J. Pinkston, C.D. Ruppel
2002, Geophysical Research Letters (29) 1-82
Using von Herzen and Maxwell's needle probe method, we measured thermal conductivity in four porous mixtures of quartz sand and methane gas hydrate, with hydrate composing 0, 33, 67 and 100% of the solid volume. Thermal conductivities were measured at a constant methane pore pressure of 24.8 MPa between -20...
Rocky Mountain futures: An ecological perspective
Jill Baron, editor(s)
2002, Book
The Rocky Mountain West is largely arid and steep, with ecological scars from past human use visible for hundreds of years. Just how damaging were the past 150 years of activity? How do current rates of disturbance compare with past mining, grazing, and water diversion activities? In the face of...
The 1999 Izmit, Turkey, earthquake: A 3D dynamic stress transfer model of intraearthquake triggering
R.A. Harris, J.F. Dolan, R. Hartleb, S.M. Day
2002, Bulletin of the Seismological Society of America (92) 245-255
Before the August 1999 Izmit (Kocaeli), Turkey, earthquake, theoretical studies of earthquake ruptures and geological observations had provided estimates of how far an earthquake might jump to get to a neighboring fault. Both numerical simulations and geological observations suggested that 5 km might be the upper limit if there were...

Arsenic species and chemistry in groundwater of southeast Michigan
M.-J. Kim, J. Nriagu, S. Haack
2002, Environmental Pollution (120) 379-390
Groundwater samples, taken from 73 wells in 10 counties of southeast Michigan in 1997 had arsenic concentrations in the range of 0.5 to 278 μg/l, the average being 29 μg/l. About 12% of these wells had arsenic concentrations that exceeded the current USEPA's maximum contaminant level of 50 μg/l. Most...
