Was the Late Paleocene-Early Eocene Hot Because Earth Was Flat? An Ocean Lithium Isotope View of Mountain Building,Continental Weathering, Carbon Dioxide,and Earth's Cenozoic Climate
Late Paleocene-Early Eocene Hot Earth Was Flat Ocean Lithium Isotope View Mountain Building Continental Weathering Carbon Dioxide Earth's Cenozoic Climate
2015/7/17
Hothouse climates in Earth's geologic past, such as the Eocene epoch, are thought to have been caused by the release of large amounts of carbon dioxide and/or methane, which had been stored as carbon ...
Stable isotope estimates of evaporation : inflow and water residence time for lakes across the United States as a tool for national lake water quality assessments
inflow water residence
2014/11/28
We used water d2H and d18O from ca. 1000 lakes sampled in the 2007 U.S. Environmental Protection Agency’s
National Lakes Assessment (NLA) to assess two hydrological variables—evaporation as a percent...
Midwater zooplankton and suspended particle dynamics in the North Pacific Subtropical Gyre: A stable isotope perspective
North Pacific Subtropical Gyre Midwater zooplankton
2014/4/2
We used amino acid (AA) compound-specific isotope analysis (d15NAA and d13
CAA values) of midwater
zooplankton and suspended particles to examine their dynamics in the mesopelagic zone. Suspended pa...

Sulfur stable isotope indicators of residency in estuarine fish
Sulfur stable isotope indicators of residency estuarine fish
2014/4/4
Estuarine fish may remain as residents in areas with favorable conditions for feeding and refuge, but become mobile and transient where conditions are less favorable. We developed a new approach invol...

Temporal spatial variability in the cycling of nitrogen a constructed wetland A whole-system stable-isotope-addition experiment
2014/4/17
Constructed wetlands attenuate effluent nutrients, are hydrodynamically well defined, and are a useful proxy for the study of nitrogen (N) transformation in eutrophic natural systems. A whole-system s...

Stable isotope fractionation during the methanogenic degradation of organic matter in the sediment of an acidic bog lake, Lake Grosse Fuchskuhle
Stable isotope fractionation during the methanogenic degradation of organic matter in the sediment an acidic bog lake Lake Grosse Fuchskuhle
2014/4/16
Lake Grosse Fuchskuhle is an acidic bog lake, which develops an anoxic hypolimnion during the summer season, so that sediment organic matter is degraded anaerobically to CH4and CO2. The d13 C values o...
