Diffusion samplers were installed in the bottom of Johns Pond, Cape Cod, Massachusetts, to confirm that volatile organic compounds from the Storm Drain-5 (SD-5) plume emanating from the Massachusetts Military Reservation (MMR) were discharging into the pond. An array of 134 vapor-diffusion samplers was buried by divers about 0.5 feet below the pond bottom in the presumed discharge area...

During this study, 369 benthic-invertebrate samples were collected at 21 sites and 33 streambed-sediment samples were collected at 14 sites to help develop and evaluate control strategies to mediate the impact of point and nonpoint sources of pollution on the White River and selected tributaries in and near Indianapolis, Indiana. Data analyses show that 124 taxa were identified and that...

This report summarizes major findings about water quality in the upper Colorado River basin that emerged from an assessment conducted between 1996 and 1998 by the U.S. Geological Survey (USGS) National Water Quality Assessment (NAWQA) Program. Water quality is discussed in terms of local and regional issues and compared to conditions found in all 36 NAWQA study areas assessed to date...

A feeding trial was conducted to determine the effect of supplementing a diet based on hydrolyzed fish meal with either 6% chitin (as ground krill shell), 6% squid meal, or 200 mg carotenoid pigment (canthaxanthin) per kilogram on dorsal fin erosion in juvenile steelhead Oncorhynchus mykiss. Three hundred fry in triplicate tanks were fed one of the four test diets, and 300 fry in a...

Using data from an ongoing study of juvenile Atlantic salmon growth and survival in tributaries of the Connecticut River, USA, we compare standard population-level approaches to those focusing on individuals. We highlight the potential benefits of resampling individually tagged stream fish as compared to standard approaches. Specifically we focus on growth, survival, movements and...

Part of the 1999 Industrial Minerals Review. A review of the state of the global industrial diamond industry in 1999 is presented. World consumption of industrial diamond has increased annually in recent years, with an estimated 500 million carats valued between $650 million and $800 million consumed in 1999. In 1999, the U.S. was the world's largest market for industrial diamond and was...

Fall 1999 was among the poorest seasons in this banding station's 20 years of operation. Record high capture totals were set for only two species: Ruby-throated Hummingbird (41 individuals captured, none banded; previous high 21) and White-breasted Nuthatch (two individuals banded; previous high, one). The only other species that stood out as being unusually numerous was Blackpoll...

In a slight reorganization, the Mount Nebo station in the mountains of western Maryland near Oakland was moved to Region III (Western Ridge), in exchange for Lakeshore Estates in Leon County, Florida, which we welcome to Region IV. This was the year of the hurricane in Region IV, with the majority of stations commenting on summer drought, persistent easterly winds, or hurricanes. Nine of...

Golden Bear Oil or GB-1111 is a petroleum distillate that is used throughout the United States as a larvicide for mosquito pupae. The oil forms a barrier at the air-water interface, which suffocates air-breathing insects. There are few published studies on non-target effects of GB-1111 but the product label warns that ?GB-1111 is toxic to fish and other aquatic organisms.? Fertile eggs...
