Geomorphic-Geodynamic Coupling at the Orogen Scale

One of the most provocative - yet largely untested - recent hypotheses concerning orogenic evolution is that regional variations in climate strongly influence spatial variations in the style and magnitude of deformation across an actively deforming orogen. Recent progress in quantifying rates of both tectonic and geomorphic processes and in modeling surface and lithospheric processes sets the stage for an integrated, quantitative, field- and model-based investigation of the interactions and feedbacks between geomorphic, climatic, and tectonic processes.

Snow Hydrology Research Group

The Snow Hydrology Research Group is part of the Donald Bren School of Environmental Science and Management at the University of California, Santa Barbara. It is also a member of the ESIP Federation (Earth Science Information Partners). The primary research focus of this group is NASA's REASoN (Research, Education and Applications Solutions Network) investigation called "Multi-Resolution Snow Products for the Hydrologic Sciences." The group also works on problems of snow metamorphism, snow-climate interactions, and snowmelt runoff.

Biogeography Lab

Since 1991 the Biogeography Lab has conducted research on the ecology, distribution and conservation of species and ecosystems using field studies, geographic information systems and remote sensing.
Through our research we help planners and resource managers protect, manage and restore productive and diverse ecosystems in California, the U.S. and internationally.

Matthew Rioux

I use high-precision ID-TIMS U-Pb geochronology, radiogenic isotope tracers and geochemistry to study magmatic and tectonic processes. My current research projects include: 1. the tectonic development of the Oman-UAE ophiolite; 2. timescales of magmatism and crustal accretion at modern mid-ocean ridges; and 3. the link between plutonism and volcanism in the Aleutian arc.

I study the most interesting billion years of life's history- the Neoproterozoic and Mesoproterozoic Eras (~1600 to 540 million years ago). This is when eukaryotes (cells with nuclei) became more diverse and abundant and I want to understand more about how that happened and why it happened when it did. During this time there were also major changes in the chemistry of Earth's atmosphere and oceans and there were at least two global glaciations. With my research I am working to understand life's role in that changing world.

Susannah Porter

My research focuses on the early evolution and radiation of eukaryotes and its relationship to environmental change, and the fossil record of the earliest skeletal animals. Research uses fieldwork, descriptive systematics, comparisons with modern taxa, paleoecological and taphonomic analyses, and stable isotopic studies.

Duane DeVecchio

Duane DeVecchio is a broad field-based geologist with a background in structural geology and geomorphology. His research involves integrating a suite of Quaternary geochronological techniques, geologic mapping, and GIS-based topographic analysis to quantify the timing and rates of change of Earth’s surface due to depositional, denudational, and incisional processes that result from active tectonics and climate variability. DeVecchio is currently conducting research focused on the spatiotemporal tectonic and geomorphic evolution of the Western Transverse Ranges in Southern California.

My research looks at the fundamental processes at the interface between dissimiliar mineral surfaces in fluids - applications to quartz-clay interaction (pressure solution) and precipitation of carbonates on mica. Clay minerals have been shown to enhance pressure solution of quartz and carbonates. Carbonate minerals and other phases have also been shown to grow selectively within biotite cleavages but not in muscovite.

John Cottle

My main research interests lie in the field of continental tectonics and focus on combining structural analysis, geothermobarometry, igneous and metamorphic petrology with high resolution U(-Th)-Pb isotope geochronology to identify and constrain the temporal and spatial scale of processes that serve to modify and/or produce new continental crust.
