The Paytan Biogeochemistry Lab is a part of the Institute of Marine Science and the Departments of Earth and Planetary Sciences and Ocean Sciences at the University of California, Santa Cruz.
Our group's primary research interests lie in the fields of biogeochemistry, chemical oceanography and paleoceanography. We use both chemical and isotopic tracers in diverse environmental samples (water, sediments, aerosol, and vegetation) to study present and past biogeochemical processes. This research spans a wide range of temporal (seasons to millions of years) and spatial (molecular to global) scales. An over-arching goal of our research is to link changes observed in the earth and ocean systems to global changes in climate and tectonics. In addition, we are interested in natural and anthropogenically induced perturbations that affect biogeochemical processes such as nutrient cycling, methane emission from wetlands, trace metal distribution, aerosol impact on marine biota and water pollution.
For more information on who we are check our People page, for what we do check out our Projects page, and for reprints of publications resulting from our research efforts please refer to our Publications page.

Biogeochemical
research is the study of chemical and biological processes, often
which
are intrinsically coupled, operating within earth systems.
Biogeochemical interactions occur on a wide-range of spatial and
temporal scales, ranging from atomic and microbial to global and from
the distant past to the present, and operate within environments
ranging from terrestrial to marine to atmospheric.
Chemical Oceanography is the study of everything about the chemistry of the ocean based on the distribution and dynamics of elements, isotopes, atoms and molecules. This ranges from fundamental physical, thermodynamic and kinetic chemistry to interactions of ocean chemistry with biological, geological and physical processes.
Paleoceanography is the study of the history of the oceans in the geologic past with regard to circulation, chemistry, biology, geology and patterns of sedimentation. Paleoceanography data are derived from many proxies found in deep sea sediments including trace metal and isotopic composition of fossil plankton, species composition, and lithology.
