Broadening theories of soils genesis: Insights from Tanzania and simple models
Three basic assumptions of soil formation are challenged herein: the degree of chemical weathering decreases with depth; increased physical weathering due to high topographical gradients causes an increase in chemical ...
Exploration of Tektite Formation Processes through Water and Metal Content Measurements
Impact events are a significant surface-modifying process on bodies lacking frequent resurfacing by atmospheric or igneous processes. To explore the effects of impacts on surface materials, we measured water and trace ...
The Effects of Land Use and Human Activities on Carbon Cycling in Texas Rivers
I investigated how land use and human activities affect the sources and cycling of carbon (C) in subtropical rivers. Annually rivers receive a large amount of terrestrial C, process a portion of this C and return it to the ...
Fluid relationships in the Northern Gulf of Mexico using dissolved ion concentrations and strontium isotopes
Pore fluids from the slope in the Gulf of Mexico demonstrate specific ion enrichment and a range in concentration. Dissolved metal and halogen fluid concentrations and strontium isotope ratios from ten sites on the Gulf ...
