Arsenic Occurrence in New Hampshire Drinking Water
(American Chemical Society (ACS), 1999)
Experimental simulations of gas-driven eruptions: kinetics of bubble growth and effect of geometry
(Springer-Verlag; Springer-Verlag Berlin Heidelberg, 1998-02)
Simulated gas-driven eruptions using CO 2 –water-polymer systems are reported. Eruptions are initiated by rapidly decompressing CO 2 –saturated water containing up to 1.0 wt.% CO 2 . Both cylindrical test cells and a flask ...
Mio-pliocene seasonality on the snake river plain: comparison of faunal and oxygen isotopic evidence
(Elsevier, 1994-02-28)
Analysis of fish faunas and oxygen isotopic composition of a fish otolith from lacustrine deposits of southwestern Idaho provide a means of evaluating regional Miocene and Pliocene climates. A disharmonious assemblage ...
Separation of paramagnetic and ferrimagnetic susceptibilities using low temperature magnetic susceptibilities and comparison with high field methods
(Elsevier, 1994-02)
Magnetic susceptibility of rocks can be dominated by diamagnetic and paramagnetic matrix minerals, ferrimagnetic and antiferromagnetic trace minerals, or a combination. The interpretation of magnetic fabric data (anisotropy ...
Patterns in tropical leaf litter and implications for angiosperm paleobotany
(Elsevier, 1994-03)
One hectare of undisturbed Amazonian forest, containing about 175 species of trees larger than 10 cm diameter at breast height, was studied to determine the relationship between high-richness forest and the autochthonous ...
Asperity distributions and large earthquake occurrence in subduction zones
(Elsevier, 1992-09-30)
Ruff, L.J., 1992. Asperity distributions and large earthquake occurrence in subduction zones. In: T. Mikumo, K. Aki, M. Ohnaka, L.J. Ruff and P.K.P. Spudich (Editors), Earthquake Source Physics and Earthquake Precursors. ...
Sr/Mg ratios of modern marine calcite: Empirical indicators of ocean chemistry and precipitation rate
(Elsevier, 1992-05)
Holocene biotic and abiotic marine calcite have a similar range of Mg contents (0 to 22 and 4 to 21 mol% MgCO3, respectively), yet biotic calcite has Sr2+ concentrations that are consistently 1250 ppm higher than those of ...
Clonal variation in above- and below-ground growth responses of Populus tremuloides Michaux: Influence of soil warming and nutrient availability
(Kluwer Academic Publishers; Springer Science+Business Media, 1999-03)
Trembling aspen (Populus tremuloides Michx.) is the most widely distributed tree species in North America making it important to terrestrial carbon and nutrient cycles. Due to anthropogenic climate change high latitude ...
Effect of the Cretaceous Serra Geral igneous event on the temperatures and heat flow of the ParanÁ Basin, southern Brazil
(Blackwell Publishing Ltd, 1995-06)
We investigate the effects of the cooling of intrusive and extrusive igneous bodies on the temperature history and surface heat flow of the ParanÁ Basin. The Serra Geral igneous event (130–135 Ma) covered most of this basin ...
