Updated Definition and Correlation of the Lower Fifteenmile Group in the Central and Eastern Ogilvie Mountains
(Yukon Geological Survey, 2012)
Ongoing mapping, chemostratigraphy, geochronology, and stratigraphic analysis of Neoproterozoic successions in the Ogilvie Mountains requires redefinition and correlation of the Fifteenmile Group across the Proterozoic ...
Possible early foraminiferans in post-Sturtian (716-635 Ma) cap carbonates
(Geological Society of America, 2011)
Foraminifera are an ecologically important group of modern heterotrophic amoeboid eukaryotes whose naked and testate ancestors are thought to have evolved ∼1 Ga ago. However, the single-chambered agglutinated tests of these ...
Tropospheric Emissions: Monitoring of Pollution (TEMPO)
(SPIE - International Society for Optical Engineering, 2013)
TEMPO was selected in 2012 by NASA as the first Earth Venture Instrument, for launch circa 2018. It will measure atmospheric pollution for greater North America from space using ultraviolet and visible spectroscopy. TEMPO ...
Stable Isotope Geobiology

Anaerobic Methane Oxidation in Metalliferous Hydrothermal Sediments: Influence on Carbon Flux and Decoupling from Sulfate Reduction
(Wiley-Blackwell, 2012)
The anaerobic oxidation of methane (AOM) is a globally significant sink that regulates methane flux from sediments into the oceans and atmosphere. Here we examine mesophilic to thermophilic AOM in hydrothermal sediments ...
Early Neoproterozoic Basin Formation in Yukon, Canada: Implications for the Make-Up and Break-Up of Rodinia
(Geological Association of Canada, 2012)
Geological mapping and stratigraphic anaylsis of the early Neoproterozoic Fifteenmile Group in the western Ogilvie Mountains of Yukon, Canada, has revealed large lateral facies changes in both carbonate and siliciclastic ...
Uncovering the Neoproterozoic Carbon Cycle
(Nature Publishing Group, 2012)
Interpretations of major climatic and biological events in Earth history are, in large part, derived from the stable carbon isotope records of carbonate rocks and sedimentary organic matter1,2. Neoproterozoic carbonate ...
What Role for Short-Lived Climate Pollutants in Mitigation Policy?
(American Association for the Advancement of Science (AAAS), 2013)
Short-lived climate pollutants (SLCPs) include methane (CH4), black carbon (BC), tropospheric ozone, and hydrofluorocarbons (HFCs). They are important contributors to anthropogenic climate change, responsible for as much ...
Reply to Boslough: Is Greenland Pt anomaly global or local?
(Proceedings of the National Academy of Sciences, 2013)
Amazon Forest Response to Changes in Rainfall Regime: Results from an Individual-Based Dynamic Vegetation Model
(2014-02-25)
The Amazon is the largest tropical rainforest in the world, and thus plays a major role on global water, energy, and carbon cycles. However, it is still unknown how the Amazon forest will respond to the ongoing changes ...
