Wood Storks of the Birdsville Colony and swamps of the Savannah River Site: General overview of research findings, 1983--1990

Description: The population of Wood Storks (Mycteria americana) that breeds in the United States has decreased from an estimated 20,000 breeding pairs in 1930 to just under 5,000 pairs in 1980. Since 1980, the number has remained relatively stable, fluctuating between 3,500 and 5,500 breeding pairs. The decline prompted the US Fish and Wildlife Service (USFWS) to list the United States population of Wood Storks as endangered in 1984. When the US Department of Energy (USDOE) decided to restart L-Reactor on t… more

Kootenai River White Sturgeon Studies, Annual Report FY 1993.

Description: This report evaluates natural spawning of white sturgeon in the Kootenai River before, during and after the 1993 augmented discharge period. To determine how altering the operation of Libby Dam may improve conditions for natural spawning of white sturgeon in the Kootenai River, discharge from Libby Dam (with no power peaking or load following) was increased to produce 20 kcfs ([plus minus] 2 kcfs) discharge at Bonners Ferry, Idaho, for a 14 day period June 2--16. Objectives of this research wer… more

Pilot study risk assessment for selected problems at the Savannah River Site (SRS)

Description: An assessment of the health risks was made for releases of tritium and [sup 137]Cs from the Savannah River Site (SRS) at water-receptor locations downriver. Although reactor operations were shut down at the SRS in 1989, liquid wastes continue to be released to the Savannah River either by direct discharges into onsite surface waters or by groundwater transport into surface waters from waste facilities. Existing state mandates will cause the liquid waste streams from future operations to go dire… more

Possible differences in biological availability of isotopes of plutonium: Report of a workshop

Description: This paper presents the results of a workshop conducted on the apparent different bioavailability of isotopes {sup 238}Pu and {sup 239}Pu. There is a substantial body of evidence that {sup 238}Pu as commonly found in the environment is more biologically available than {sup 239}Pu. Studies of the Trinity Site, Nevada Test Site from nonnuclear and nuclear events, Rocky Flats, Enewetak and Bikini, and the arctic tundra support this conclusion and indicate that the bioavailability of {sup 238}Pu is… more

Bioavailability of sediment-bound contaminants to marine organisms

Description: The bioavailability of sediment-bound contaminants to marine organisms indicates that there exists a potential for transfer of these contaminants through marine food webs to commercial fisheries products consumed by humans. However, there has been relatively little effort to combine and synthesize data on chemical/biological interactions between benthic animals and seagrasses and the sediments in which they reside on the one hand, and on the chemistry of bioaccumulation on the other. This repor… more

Hydrologic analysis of Steel Creek and L Lake and the effects of flow reduction on Steel Creek habitat

Description: This report was prepared to support a proposal to eliminate the EIS mandated spring flow requirements in Steel Creek below L Lake. The base flow in Steel Creek below L Lake was estimated using historical data. The water balance of L Lake was studied to evaluate the effects of flow reduction on the Steel Creek hydrologic system. The base flow in Steel Creek below L Lake is estimated as 0.28 cms (10 cfs). A reduction in L Lake discharge to 0.28 cms will result in a fish community similar to the o… more

Environmental genotoxicity: Probing the underlying mechanisms

Description: Environmental pollution is a complex issue because of the diversity of anthropogenic agents, both chemical and physical, that have been detected and catalogued. The consequences to biota from exposure to genotoxic agents present an additional problem because of the potential for these agents to produce adverse change at the cellular and organismal levels. Past studies in genetic toxicology at the Oak Ridge National Laboratory have focused on structural damage to the DNA of environmental species… more

Sperm cells as vectors in the production of transgenic animals

Description: Transgenic animals are used in industry and in biomedical research in order to provide in vivo experimental model systems. Sperm cells have been reported used as vectors in the production of transgenic animals before, however no approach has of yet proven to be successful. Fertilizing eggs with genetically modified sperm would be advantageous in that sperm are readily accessible and stable, and eggs can be fertilized by modified sperm cells in vivo. Recent elucidations regarding the unique mann… more

Valuing the salmon resource: Columbia River stocks under climate change and fishery enhancement

Description: This paper represents an update to ongoing multidisciplinary research in the area of climate change and associated regional impacts to fisheries and economies. This work particularly deals with the total value of Columbia River salmon and the idea that fish have capital value, articulated here as spawning value. Earlier work dealt solely with the Yakima River spring chinook fishery`s response to climate change and fishery enhancement programs and the associated direct economic effects (Anderson… more

HEDR model validation plan. Hanford Environmental Dose Reconstruction Project

Description: The Hanford Environmental Dose Reconstruction (HEDR) Project has developed a set of computational ``tools`` for estimating the possible radiation dose that individuals may have received from past Hanford Site operations. This document describes the planned activities to ``validate`` these tools. In the sense of the HEDR Project, ``validation`` is a process carried out by comparing computational model predictions with field observations and experimental measurements that are independent of those… more

South Fork John Day River Habitat Enhancement Project : Annual Reports 1986, 1987 and Final Report.

Description: The South Fork John Day River (SFJDR) contains important wild summer steelhead habitat. Adult fish annually return to the drainage to spawn. All tributaries accessible to steelhead are used for spawning. Additionally, juvenile steelhead rear in the SFJDR and its tributaries from two to three years before migrating to the ocean. The role of the SFJDR in rearing juvenile steelhead, particularly from age 1+ to smolt, is vital to the system as a whole. Many, if not all, of the tributaries produce j… more

Electrofishing survey of the Great Miami River, September 1992. Annual report

Description: At the end of summer in 1992 the fishery of the Great Miami River took an unexpected deviation from the stasis of past years as an intense suspended algal bloom decreased the compositional diversity found at the lower GMR stations. Daytime supersaturation of oxygen and elevated pHs, reaching 9 by midday during the month of August, undoubtedly caused severe deficits of oxygen at night. Despite the aeration at every riffle, the intensities of the biological processes in the water were sufficient … more

Differential utilization of allochthonous and autochthonous carbon by aquatic insects of two shrub-steppe desert spring-streams: A stable carbon isotope analysis and critique of the method

Description: The purpose of this study is to assess whether the carbon supporting stream food webs comes principally from terrestrial sources or is produced within the stream. Lacking data to resolve the allochthonous/autochthonous issue with any finality, stream ecologists have alternately postulated that stream carbon was principally autochthonous or principally allochthonous. Others argued that autochthonous and allochthonous carbon resources cannot be separated and that the allochthonous/autochthonous d… more
