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...

The cause of deeply penetrating ulcers of Atlantic menhaden Brevoortia tyrannus has been the subject of significant research efforts in recent years. These lesions and the associated syndrome termed ulcerative mycosis have been observed along the East Coast of the United States since at least the early 1980s. Although Aphanomyces spp. were isolated from...

Water level, specific conductance, and water temperature data, San Francisco Bay, California, for Water Year 2000
P.A. Buchanan
2002, Interagency Ecological Program Newsletter (15) 22-26
Time series of water-level, specific-conductance, and watertemperature data were collected at seven sites in San Francisco Bay during water year 2000 (October 1, 1999 through September 30, 2000). Water-level data were recorded only at Point San Pablo. Specific-conductance and water-temperature data were recorded at 15-minute intervals at the following locations...
United States streamflow probabilities and uncertainties based on anticipated El Niño, water year 2003

2002, Experimental Long-Lead Forecast Bulletin (11) 46-52
During the course of spring and summer 2002, tropical sea-surface temperatures in the eastern Pacific Ocean have warmed and the wind and pressure fields have shifted, so that by August, there was considerable confidence that water year (October–September) 2003 will be characterized by a weak to mild El Niño climate...
Use of satellite telemetry to identify common loon migration routes, staging areas and wintering range
Kevin P. Kenow, Michael W. Meyer, David Evers, David C. Douglas, J. Hines
2002, Waterbirds (25) 449-458
We developed a satellite transmitter attachment technique for adult Common Loons (Gavia immer) that would help in identifying important migration routes, staging areas, and the location of wintering grounds of birds that breed in the north central United States. During the autumn and winter of 1998, the migration of...

Mycoplasmosis is a transmissible upper respiratory tract disease that has affected plans for management and conservation of wild desert and gopher tortoises in the United States. Although impact of mycoplasmosis on populations of desert and gopher tortoises is unknown, increased prevalence of seropositive animals as well as field observations of...
Temporal variations of natural and anthropogenic radionuclides in sea otter skull tissue in the North Pacific Ocean

Marine mammals being among the top predators in the food web tend to accumulate organic and inorganic contaminants from the environment. The body burden of contaminants in these species could reflect their foods and thus contaminant levels could serve as proxies on the changes of ecosystem. A pilot study was...

Using groundwater levels to estimate recharge
R. W. Healy, P.G. Cook
2002, Hydrogeology Journal (10) 91-109
Accurate estimation of groundwater recharge is extremely important for proper management of groundwater systems. Many different approaches exist for estimating recharge. This paper presents a review of methods that are based on groundwater-level data. The water-table fluctuation method may be the most widely used technique for estimating recharge; it requires...

In 1996, the Smithsonian Tropical Research Institute and the Republic of Panama's Environmental Authority, with support from the United States Agency for International Development, undertook a comprehensive program to monitor the ecosystem of the Panama Canal watershed. The goals were to establish baseline indicators for the integrity of forest communities...
Advances in directional borehole radar data analysis and visualization
D.V.G. Smith, P.J. Brown II
2002, Conference Paper, Proceedings of SPIE - The International Society for Optical Engineering
The U.S. Geological Survey is developing a directional borehole radar (DBOR) tool for mapping fractures, lithologic changes, and underground utility and void detection. An important part of the development of the DBOR tool is data analysis and visualization, with the aim of making the software graphical user interface (GUI) intuitive...
Regional patterns of pesticide concentrations in surface waters of New York in 1997
Patrick J. Phillips, David A. Eckhardt, Douglas A. Freehafer, Gary R. Wall, H. H. Ingleston
2002, Journal of the American Water Resources Association (38) 731-745
The predominant mixtures of pesticides found in New York surface waters consist of five principal components. First, herbicides commonly used on corn (atrazine, metolachlor, alachlor, cyanazine) and a herbicide degradate (deethylatrazine) were positively correlated to a corn-herbicide component, and watersheds with the highest corn-herbicide component scores were those in which...
Improved method for quantifying the avicide 3-chloro-p-toluidine hydrochloride in bird tissues using a deuterated surrogate/GC/MS method
Randal S. Stahl, Thomas W. Custer, P. A. Pochop, J. J. Johnston
2002, Journal of Agricultural and Food Chemistry (50) 732-738
A method using a deuterated surrogate of the avicide 3-chloro-p-toluidine hydrochloride (CPTH) was developed to quantify the CPTH residues in the gastrointestinal (GI) tract and breast muscle tissues in birds collected in CPTH-baited sunflower and rice fields. This method increased the range of a previous surrogate/gas chromatography/mass spectroscopy method...
The relationship between the abundance of smallmouth bass and double-crested cormorants in the eastern basin of Lake Ontario
Brian F. Lantry, Thomas H. Eckert, Clifford P. Schneider, Jana R. Chrisman
2002, Journal of Great Lakes Research (28) 193-201
Available population and diet data on double-crested cormorant (Phalacrocorax auritus) and smallmouth bass (Micropterus dolomieui) numbers, demographics, and exploitation rates were synthesized to examine the relationship between cormorant and smallmouth bass abundance in the U.S. waters of the eastern basin of Lake Ontario....
Field estimate of net trophic transfer efficiency of PCBs to Lake Michigan chinook salmon from their prey

2002, Environmental Science & Technology (36) 5029-5033
Chinook salmon (Oncorhynchus tshawytscha) has been the predominant piscivore in Lakes Michigan, Huron, and Ontario since the 1970s, and therefore accurate quantification of its energy budget is needed for effective management of Great Lakes fisheries. A new approach of evaluating a fish bioenergetics model in the field involves field estimation...
Ecological potential of the Grand Calumet River basin
Richard L. Whitman, Meredith Becker Nevers, Shira Hammann, Philip B. Moy
2002, Proceedings of the Indiana Academy of Science (108/109) 163-175
The Grand Calumet River and watershed have been severely degraded by industrialization and urbanization, and yet several high-quality natural areas remain intact. The degraded condition presents numerous opportunities for pollution mitigation and ecosystem restoration. In many areas of the river and watershed, biological communities are characterized by low...

C.P. Rice, S.M. Chernyak, L. Begnoche, R. Quintal, J. Hickey
2002, Chemosphere (49) 731-737
Polybrominated diphenyl ethers (PBDEs) were identified in fish collected from the Detroit River, MI and Des Plaines Rivers, IL. In the Detroit River fish, carp and large mouth bass, the congener patterns were dominated by the 2,2′,4,4′-tetrabromo (BDE-47) congener; however, in Des Plaines River carp the dominant isomers were the...
