The mean composition of ocean ridge basalts
(Wiley-Blackwell, 2013)
The mean composition of mid-ocean ridge basalts (MORB) is determined using a global data set of major ele- ments, trace elements, and isotopes compiled from new and previously published data. A global catalog of 771 ridge ...
The Processes of Melt Differentiation in Arc Volcanic Rocks: Insights from OIB-type Arc Magmas in the Central Mexican Volcanic Belt
(Oxford University Press (OUP), 2013)
Andesite petrogenesis is inextricably linked to plate processing at convergent margins. The details of andesite formation, however, remain poorly understood because the signatures of the initial arc mantle melts are often ...
Probing the Dynamics of Shallow Cumulus Convection
(2013-10-18)
Our limited knowledge of convection and its poor representation in climate models is one of the factors that most hamper our ability to understand and predict the climate system. In this thesis, the dynamics of shallow ...
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 ...
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)
Dynamically and Kinematically Consistent Global Ocean Circulation and Ice State Estimates
(Elsevier BV, 2013)
The World Ocean Circulation Experiment drove the development of estimates of the decadal scale time evolving general circulation that are dynamically and kinematically consistent. A long timescale, and a goal of estimation ...
Medieval Irish Chronicles Reveal Persistent Volcanic Forcing of Severe Winter Cold Events, 431–1649 CE
(IOP Publishing, 2013)
Explosive volcanism resulting in stratospheric injection of sulfate aerosol is a major driver of regional to global climatic variability on interannual and longer timescales. However, much of our knowledge of the climatic ...
The Stratigraphic Relationship Between the Shuram Carbon Isotope Excursion, the Oxygenation of Neoproterozoic Oceans, and the First Appearance of the Ediacara Biota and Bilaterian Trace Fossils in Northwestern Canada
(Elsevier BV, 2013)
A mechanistic understanding of relationships between global glaciation, a putative second rise in atmospheric oxygen, the Shuram carbon isotope excursion, and the appearance of Ediacaran-type fossil impressions and ...
Searching for an oxygenation event in the fossiliferous Ediacaran of northwestern Canada
(Elsevier BV, 2013)
Late Neoproterozoic (Ediacaran) strata from northwestern Canada provide a thick and rich sedimentological record, preserving intercalated carbonates and shale extending from the ~ 635 million year old Marinoan glacial ...
