Uranium biogeochemistry across the redox transition zone of a permanently stratified fjord: Framvaren, Norway
P.W. Swarzenski, B.A. McKee, J.M. Skei, J.F. Todd
1999, Marine Chemistry (67) 181-198
During August 1995, the vertical concentration profile of dissolved and particulate uranium exhibited strong non-conservative characteristics in the upper 30 m of Framvaren Fjord. There was a pronounced peak in both particulate (> 0.2 ??m; 1.09 nM) and dissolved (< 0.2 ??m; 17.06 nM) uranium in the finely stratified waters...
Flooding and fish diversity in a reclaimed river-wetland
C.H. Theiling, J.K. Tucker, F.A. Cronin
1999, Journal of Freshwater Ecology (14) 469-475
Attempts at large river restoration are few and largely experimental. We studied a newly constructed river-wetland project on the upper Mississippi River three years after its completion. Species inventories for fish began to be compiled in the spring of 1993. Coincidentally, record rainfall throughout the midwest resulted in...
Comparison of aerial survey procedures for estimating polar bear density: Results of pilot studies in northern Alaska
Lyman L. McDonald, Gerald W. Garner
Gerald W. Garner, Steven C. Amstrup, Jeffrey L. Laake, Bryan F.J. Manly, Lyman L. McDonald, Donna G. Robertson, editor(s)
1999, Conference Paper, Marine mammal survey and assessment methods
The U.S. Marine Mammal Protection Act (MMPA) and International Agreement on the Conservation of Polar Bears mandate that boundaries and sizes of polar bear (Ursus maritimus) populations be known so they can be managed at optimum sustainable levels. However, data to estimate polar bear numbers for the Chukchi/Bering Sea and...

Deep-sea ostracode species diversity: Response to late Quaternary climate change
T. M. Cronin, D.M. DeMartino, Gary S. Dwyer, J. Rodriguez-Lazaro
1999, Marine Micropaleontology (37) 231-249
Late Quaternary ostracode assemblages from the North Atlantic Ocean were studied to establish the effect of climatic changes of the past 210,000 yr (marine oxygen isotope stages 7–1) on deep-sea benthic biodiversity and faunal composition. Two-hundred and twenty five samples from the Chain 82-24 Core 4PC (41°43′N, 32°51′W, 3427 m...
Early Devonian (late Emsian) Brachiopods from Zhongping, Xiangzhou, central Guangxi, China
X.-Q. Chen, Z.-G. Yao
1999, Senckenbergiana Lethaea (79) 223-265
The brachiopod fauna (20 species in 6 genera) from the Ma'anshan section of the Emsian Dale Formation at Zhongping, Xiangzhou county, central Guangxi is described. The fauna is dominated by spire-bearing brachiopods. One new genus and 4 new species are proposed: the smooth-shelled, septalium-bearing Lubricospirifer gumoensis gen. et sp. nov.,...
Seafloor environments in the Long Island Sound estuarine system
H.J. Knebel, R. P. Signell, R.R. Rendigs, L.J. Poppe, J. H. List
1999, Marine Geology (155) 277-318
Four categories of modern seafloor sedimentary environments have been identified and mapped across the large, glaciated, topographically complex Long Island Sound estuary by means of an extensive regional set of sidescan sonographs, bottom samples, and video-camera observations and supplemental marine-geologic and modeled physical-oceanographic data. (1) Environments of erosion or nondeposition...
The effects of copper on blood and biochemical parameters of rainbow trout (Oncorhynchus mykiss)
G.M. Dethloff, D. Schlenk, S. Khan, H.C. Bailey
1999, Archives of Environmental Contamination and Toxicology (36) 415-423
Metals are released into aquatic systems from many sources, often at sublethal concentrations. The effects of sublethal concentrations of metals on fish are not entirely understood. The objective of this study was to determine the hematological and biochemical effects of a range of copper concentrations (6.4, 16.0, 26.9 ??g Cu/L)...

The relative importance of light and nutrient limitation of phytoplankton growth: A simple index of coastal ecosystem sensitivity to nutrient enrichment
J. E. Cloern
1999, Aquatic Ecology (33) 3-16
Anthropogenic nutrient enrichment of the coastal zone is now a well-established fact. However, there is still uncertainty about the mechanisms through which nutrient enrichment can disrupt biological communities and ecosystem processes in the coastal zone. For example, while some estuaries exhibit classic symptoms of acute eutrophication, including enhanced production of...
Temporal trends of bulk precipitation and stream water chemistry (1977-1997) in a small forested area, Krusne hory, northern Bohemia, Czech Republic
N.E. Peters, J. Cerny, M. Havel, R. Krejci
1999, Hydrological Processes (13) 2721-2741
The Krusne hory (Erzgebirge or Ore Mountains) has been heavily affected by high atmospheric pollutant deposition caused by fossil fuel combustion in an adjacent Tertiary coal basin. Long-term routine sampling of bulk precipitation (1977-1996) and stream water (1977-1998) in a forested area on the south-eastern slope of the mountains were...
Utilization of the gypsum from a wet limestone flue gas desulfurization process
I.-M. Chou, V. Patel, J.M. Lytle, S.J. Chou, R.H. Carty
1999, Conference Paper, Proceedings of the International Conference on Solid Waste Technology and Management
The authors have been developing a process which converts FGD-gypsum to ammonium sulfate fertilizer with precipitated calcium carbonate as a by-product during the conversion. Preliminary cost estimates suggest that the process is economically feasible when ammonium sulfate crystals are produced in a granular size (1.2 to 3.3 mm), instead of...
Environmental geology: Our professional public responsibility
L. C. Gerhard, L. L. Brady
1999, Environmental Geology (37) 1-8
Conflicts between different interest groups for use of natural resources is one area where state geological surveys can provide assistance. A state geological survey working within the scientific constraints of specific issues can remain objective in its presentations and maintain the faith of both the conflicting interest groups and the...
Cross-well slug testing in unconfined aquifers: A case study from the Sleepers River Watershed, Vermont
Kenneth Belitz, W. Dripps
1999, Ground Water (37) 438-447
Normally, slug test measurements are limited to the well in which the water level is perturbed. Consequently, it is often difficult to obtain reliable estimates of hydraulic properties, particularly if the aquifer is anisotropic or if there is a wellbore skin. In this investigation, we use partially penetrating stress and...

Outcrop-scale acoustic facies analysis and latest Quaternary development of Hueneme and Dume submarine fans, offshore California
D.J.W. Piper, R.N. Hiscott, W. R. Normark
1999, Sedimentology (46) 47-78
The uppermost Quaternary deposits of the Hueneme and Dume submarine fans in the Santa Monica Basin have been investigated using a closed-spaced grid of boomer seismic-reflection profiles, which give vertical resolution of a few tens of centimetres with acoustic penetration to 50 m. Acoustic facies integrated with geometry define six...

Comparative microhabitat use of ecologically similar benthic fishes
E. van Snik Gray, Jay R. Stauffer Jr.
1999, Environmental Biology of Fishes (56) 443-453
Although benthic insectivorous fishes such as darters and sculpins represent a significant component of riffle communities, few studies have compared the habitat use of these non-related but ecologically similar fishes. The objectives of this study were to examine the habitat use of Etheostoma olmstedi (tessellated darter) compared to Cottus bairdi...
Conservation endocrinology: A noninvasive tool to understand relationships between carnivore colonization and ecological carrying capacity
J. Berger, J.W. Testa, T. Roffe, S.L. Monfort
1999, Conservation Biology (13) 980-989
Reproductive technology, especially the diagnosis of pregnancy by radioimmunoassay of fecal steroid metabolites, is an important component of captive propagation, but its role in our understanding of ecological interactions and in situ biological restoration has been more limited. Where large herbivores have been 'released' from predation by the extirpation of...

Management of groundwater supply and water quality in the Los Angeles Basin, California
E.G. Reichard, S.M. Crawford, M.T. Land, K.S. Paybins
1999, Conference Paper, IAHS-AISH Publication
Water use and water needs in the coastal Los Angeles Basin in California have been very closely tied to the development of the region during the last 150 years. The first water wells were drilled in the mid-1800s. Currently about 40% of the water supply (9.4 m3 s-1) in the...
