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 ...
Reconstruction of eastern Pacific climate variability using multiple geochemical tracers in Cocos Island corals
Multiple isotopic and geochemical tracers were employed to unravel the complex history of recent environmental variability at Cocos Island. Downcore variations in delta18O, U/Ca, Sr/Ca, and Ba/Ca within coral skeletal ...
