Bright-orange floating matter (possibly algae) has been observed in the United States supply of some ampoules and in one of two 10-L primary glass storage flasks of the isotopic reference water VSMOW (Vienna Standard Mean Ocean Water). Within experimental error, ampoules with and without this orange matter are identical in stable hydrogen and...

Modeling mangrove canopy reflectance using a light interaction model and an optimization technique
Elijah Ramsey III, John R. Jensen
1995, Book chapter, Wetland and Environmental Applications of GIS
At 20 sites, incorporating mixtures of black, red, and white mangroves, canopy reflectance spectra were derived from high resolution spectral data taken from a helicopter platform. Canopy characteristics were predicted from the canopy reflectance spectra by using measured and estimated data as inputs into a light-canopy interaction model within a...

Disturbance and recovery of the Louisiana coastal marsh landscape from the impacts of Hurricane Andrew
Glenn R. Guntenspergen, Donald R. Cahoon, James B. Grace, Gregory D. Steyer, Stephen Fournet, M. A. Townson, A. Lee Foote
1995, Journal of Coastal Research (SI) 324-339
The impact of Hurricane Andrew on the Louisiana coastal landscape and the initial recovery of wetland plant communities was determined from extensive surveys of a large geographic region of coastal marsh near Atchafalaya Bay and intensive studies of an oligohaline marsh on Otter Bayou. Wind and water movements associated with...

Porphyry copper and other intrusion-related mineralization in Mexico
Mark D. Barton, John-Mark G. Staude, Lukas Zurcher, Peter K. M. Megaw
1995, Book chapter, Porphyry copper deposits of the American Cordillera
Intrusion-related copper-bearing ore deposits in Mexico span a wide-range of deposit types and geological settings and formed from the mid-Mesozoic through the Holocene. These deposits include world-class copper porphyry and skarn deposits as well as a continuum of similar skarn, porphyry, vein, and replacement deposits that contain variable quantities of...

Structure, vein paragenesis, and alteration in the Al Wajh gold district, Saudi Arabia
P. James LeAnderson, Mahmoud Yoldash, Peter R. Johnson, Terry W. Offield
1995, Economic Geology (90) 2262-2273
The Al Wajh gold district contains small deposits of gold-bearing quartz veins located in sheared and altered Neoproterozoic mafic lavas and volcaniclastic sandstone and siltstone. The veins formed during multiple episodes of deformation and have structual and mineralogic features characteristic of mesothermal, low sulfide, gold-bearing quartz veins. Three early deformation...
Sources of the Early Cretaceous plutons in the Turtle and West Riverside Mountains, California
C. M. Allen, J. L. Wooden, Keith A. Howard, D.A. Foster, R. M. Tosdal
1995, Journal of Petrology (36) 1675-1700
Ages and initial isotopic ratios of Early Cretaceous (˜100 Ma) plutons of the Cordilleran Interior in the southern Turtle and West Riverside mountains distinguish them from Late Cretaceous plutons in surrounding ranges in the eastern Mojave Desert. Furthermore, the studied plutons have isotopic and geochemical characteristics more similar to plutons...
The generation of oceanic rhyolites by crystal fractionation: the basalt-rhyolite association at Volcán Alcedo, Galápagos archipelago
Dennis Geist, Keith A. Howard, Peter Larson
1995, Journal of Petrology (36) 965-982
Alcedo volcano is one of six shield volcanoes on Isabela Island in the western Galápagos Islands. Although Alcedo is dominantiy basaltic, it is unusual in that it also has erupted ∼1 km3 of rhyolite. The rhyolitic phase marked a 10-fold decrease in the mass-eruption rate of the volcano, and the volcano...
Rules for success in environmental negotiations
J. G. Taylor, N. Burkardt, B. L. Lamb
1995, Conference Paper, Waterpower '95, Proceedings of the International Conference on Hydropower
Scientists at the Mid-Continent Ecological Science Center of the National Biological Service conducted a series of case studies of Federal Energy Regulatory Commission license consultations. The goal of these studies was to test hypotheses about factors that contribute to success in interagency negotiations. Based on their analysis of six case...
Continental drilling for paleoclimatic records: Recommendations from an international workshop
Steve M. Colman, editor(s)
1995, Report
The Workshop, entitled "Continental Drilling for Paleoclimate Records", was sponsored by the Past Global Changes (PAGES) Project, a core project of the International Geosphere-Biosphere Programme (IGBP) and by the GeoForschungsZentrum, Potsdam, Germany, in conjunction with the International Continental Drilling Programme (ICDP). The impetus for the meeting was the need for...

Seafloor environments within the Boston Harbor- Massachusetts Bay sedimentary system: A regional synthesis
H.J. Knebel, R.C. Circe
1995, Journal of Coastal Research (11) 230-251
Modern seafloor sedimentary environments within the glaciated, topographically complex Boston Harbor and Massachusetts Bay area have been interpreted and mapped from an extensive collection of sidescan sonar records and supplemental marine geologic data. Three categories of environments are present that reflect the dominant long-term processes of erosion or nondeposition,...

Geometry of sandy deposits at the distal edge of the Mississippi Fan, Gulf of Mexico
D.C. Twichell, W. C. Schwab, Neil H. Kenyon
1995, Book chapter, Atlas of Deep Water Environments
Sidescan sonar provides a map of the seafloor that has greatly improved the understanding of depositional processes on modern deep-sea fans (e.g. Mutti and Normark 1991). Here, we present a sidescan-sonar mosaic from the eastern Gulf of Mexico that images the distal reaches of a channel on the Mississippi Fan...

Postembryonic growth and development of Hyalella azteca in laboratory cultures and contaminated sediments
M.K. Nelson, Eric L. Brunson
1995, Chemosphere (31) 3129-3140
The environmental, biological, and ecological requirements of but a few species used in testing sediments are known and well understood. The present investigation was designed to provide fundamental information on the postembryonic growth and development of Hyalella azteca">Hyalella azteca (Amphipoda) that can be used as sublethal...
Influences on copper bioaccumulation, growth, and survival of the midge, Chironomus tentans, in metal-contaminated sediments
John M. Besser, Jody A. Kubitz, Chris G. Ingersoll, W. Emmett Braselton, John P. Giesy
1995, Journal of Aquatic Ecosystem Health (4) 157-168
Sediment bioassays with larvae of the midge, Chironomus tentans, were used to evaluate influences on the bioavailability and toxicity of copper (Cu) in sediments with a wide range of concentrations of metals, acid-volatile sulfide (AVS), and other physicochemical characteristics. Sediments were collected from sixteen lakes in Michigan, USA, and...
