Land-ocean contrasts under climate change
(Massachusetts Institute of Technology, 2015)
Observations and climate models show a pronounced land-ocean contrast in the responses of surface temperature and the hydrological cycle to global warming: Land temperatures increase more than ocean temperatures, low-level ...
Gulf stream temperature, salinity and transport during the last millennium
(Massachusetts Institute of Technology, 2006)
Benthic and planktonic foraminiferal [delta]18O ([delta 18Oc) from a suite of well-dated, high-resolution cores spanning the depth and width of the Straits of Florida reveal significant changes in Gulf Stream cross-current ...
Land-atmosphere interaction and radiative-convective equilibrium
(Massachusetts Institute of Technology, 2014)
I present work on several topics related to land-atmosphere interaction and radiative-convective equilibrium: the first two research chapters invoke ideas related to land-atmosphere interaction to better understand ...
Evolution of oceanic margins : rifting in the Gulf of California and sediment diapirism and mantle hydration during subduction
(Massachusetts Institute of Technology, 2013)
This thesis investigates three processes that control the evolution of oceanic margins. Chapter 2 presents seismic images of a ~2-km-thick evaporite body in Guaymas Basin, central Gulf of California. In rifts, evaporites ...
Geochemistry and petrology of recent volcanics of the Puyehue-Cordon Caulle Area, Chile (40.5S̊)
(Massachusetts Institute of Technology, 1985)
The role of colloidal organic matter in the marine geochemistry of PCB's
(Massachusetts Institute of Technology, 1986)
Little Ice Age climate in the western tropical Atlantic inferred from coral geochemical proxies
(Massachusetts Institute of Technology, 2016)
Paleoclimate archives place the short instrumental record of climate variability in a longer temporal context and allow better understanding of the rate, nature and extent by which anthropogenic warming will impact natural ...
Surface uplift, fluvial incision, and geodynamics of plateau evolution, from the western margin of the Central Andean plateau
(Massachusetts Institute of Technology, 2008)
The Colca-Majes and Cotahuasi-Ocona rivers in southwest Peru that cut through the western margin of the Andean plateau en route to the Pacific Ocean incised canyons over 3 km deep in response to late Cenozoic surface uplift. ...
