Spatial distribution and seasonal variation in 18 O/ 16 O of modern precipitation and river water across the conterminous USA
(John Wiley & Sons, Ltd., 2005-12-30)
We report a quantitative analysis of regional differences in the the oxygen isotope composition of river water and precipitation across the USA because data are now available to undertake a more geographically and temporally ...
A simulation model of river ice cover thermodynamics
(Elsevier, 1985-04)
A model of ice cover thermodynamics was used to simulate ice growth and decay along the international section of the St. Lawrence River for winter 1980-1981. This winter was chosen because of the exceptionally cold weather ...
Geochemistry of rare earth elements in pacific hydrothermal sediments
(Elsevier, 1988-10)
The concentrations and mass accumulation rates of rare earth elements (REE) in hydrothermal sediments from two Pacific sites support earlier predictions that hydrothermal REE inputs are significant to the overall marine ...
Bioaccumulation and histopathological effects of oil on a stony coral
(Elsevier, 1981-10)
Colonies of the shallow-water Caribbean coral Manicina areolata incorporated petroleum hydrocarbons into their tissues during exposure to water accommodated fractions of No. 2 fuel oil for three months. This contamination ...
Impact of Carbonate Precipitation on Riverine Inorganic Carbon Mass Transport from a Mid-continent, Forested Watershed
(Kluwer Academic Publishers; Springer Science+Business Media, 2004-03)
Physiochemical controls on the carbonate geochemistry of large river systems are important regulators of carbon exchange between terrestrial and marine reservoirs on human time scales. Although many studies have focused ...
Fractal physiography?
(Elsevier, 1994-12)
Fractal geometric parameters were employed to assess the morphometric viability of traditionally defined physiographic provinces using relatively coarse 30-arc-second digital elevation models (DEM) within 1[deg] x 1[deg] ...
Soil temperature and electric potential during diurnal and seasonal freeze-thaw
(Elsevier, 1989-07)
Combined measurements of soil temperature and electric potential in the upper 15 cm of a glacial sandy-loam soil were made during the winters of 1986-1987 and 19871988 at the University of Michigan Botanical Gardens using ...
Diagenesis of vascular plant organic matter components during burial in lake sediments
(Kluwer Academic Publishers; Springer Science+Business Media, 1995-03)
Diagenetic changes are difficult to distinguish from variations in sources of organic matter to sediments. Organic geochemical comparisons of samples of wood, bark, and needles from a white spruce ( Picea glauca ) living ...
A simple energy balance model of ice segregation
(Elsevier, 1980-05)
Step functions of normal frost front advance in dry and wet soils are reviewed and used to introduce the geometry of the soil frost system. An energy balance equation at the initiation of ice lens growth is developed using ...
