Earth Systems Science

Matthew Jackson

Professor Jackson uses the isotopic and chemical composition of lavas erupted at plume-fed hotspot volcanoes to gain insight into the make-up of the Earth’s deep interior. In particular, he is interested in understanding the origins (recycling of subducted material, metasomatism, etc) and length scales (hemispheric to micron-scale) of heterogeneities in the mantle. He employs innovative in situ techniques to get at the composition of lavas, phenocrysts and the melt inclusions they host.

Thiago Silva

I study the ecosystem processes on floodplains of the Amazon basin. My approach combines field data with multi-temporal satellite data and is making an important contribution to understanding of carbon dynamics in tropical wetlands. 

Jay Means

Over the course of his career, Jay Means has been involved in developing trace analytical methodology and its application to the analysis of environmental media including water, sediments, biological tissues, colloidal materials and air. He has published more than one hundred papers in the areas of trace analytical chemistry, environmental chemistry, and environmental toxicology of hydrophobic organic chemicals in aquatic systems ranging from the Great Lakes and major U.S. river systems to estuaries in the Chesapeake Bay, San Francisco Bay, the Gulf of Mexico, and U.S.

Measures Ocean Color Project

Satellite ocean color data products are all too frequently relegated to a single, unique product, the chlorophyll concentration. However, the ocean color signal (the normalized water-leaving radiance spectrum, LwN(lambda)) contains information about other water components or processes such as the concentrations and type of suspended particulate and dissolved materials, the composition of the phytoplankton community and the productivity of the water column.

Plumes and Blooms

Each year, winter rains wash sand, mud and other terrestrial debris into the Santa Barbara Channel. Then, during the spring and summer, phytoplankton populations increase dramatically and ultimately provide the primary energy source for the entire marine food web. These alternating patterns of brown terrestrial ‘plumes’ and green algal ‘blooms’ provide UCSB ocean color scientists with an excellent field laboratory for understanding and modeling the color of the ocean.

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.
