Research Interests:
Interdisciplinary marine science. Coupling of physical, biological, optical and biogeochemical processes on micro to ocean basin scales. Specifically, ocean color remote sensing and optical oceanography, mesoscale eddy & coastal processes, numerical modeling, Lagrangian approaches to understanding mixing and its implications, quantification of subgrid scale processes, human-natural system coupling, role of radiative exchanges in air-sea interactions and data information systems.
My Research Projects:
I am lucky to have a variety of funded projects I am working
on (due largely to the good graces of NASA and NSF). Some of these
projects I lead while others I am a contributor. They all have the
possibility of involvement of graduate and undergraduate students. Many of the
bio-optically related projects I do in collaboration with Stephane Maritorena
and Norm Nelson both are at UCSB ICESS.
Projects with reasonable webpages
(this is a little dated…) include:
Global Analyses of Ocean Color Variability - This work
focuses on analyzing time/space trends in global ocean color satellite data
sets including the merging of available satellite data sets (merged data set site).
This work is done in collaboration with Stephane Maritorena, Norm Nelson, Mike
Behrenfeld (OSU), Toby Westberry (OSU) and Jorge Sarmiento (Princeton). A
cute article on our recent Nature
paper (and me) can be accessed here.

matter pool as part of the CLIVAR Repeat Hydrography Survey - NSF / NASA - with

My Teaching:
I have a 1/2 time teaching release due to my administrative obligations to ICESS. The following are courses that I find myself teaching often. Geog 210a is for incoming graduate students and Geog 163 and 158 are undergraduate offerings. I also teach graduate offerings in advanced physical oceanography, ocean color remote sensing and ocean optics when the demand is there.
Geog 210a:
Analytical Methods for Geography Research
Introduction to
analytical methods used to geography research problems. Topics include:
calculus, vector analysis, and differential equations. Emphasis is placed on
problem statements and solutions. I end up teaching this every fall. Syllabus is available here.
Geog 163: Ocean
Circulation
Examination of the general
circulation of the oceans and its impact on global climate and climate change.
Topics covered include the properties of seawater, the forces driving ocean
currents, the wind and buoyancy generation of basin scale circulations and
their impact on global climate. I teach this every other year usually in the spring.
Class web site is available here.
Geog 158:
California Current
Introduction to the
marine resources off the California coast. The interplay of oceanographic,
climatic, biogeochemical and geologic factors and the influences of man will be
addressed. Topics will include: climate, circulation, biogeography, fisheries,
marine mammals, petroleum, pollution and exploration history. I teach this every other year (and
will teach it spring of 2009). Class web site is available here.

Synergistic Activities:
Served on a science panel for siting
marine protected areas around the Channel Islands, California. Lead the Flow, Fish
and Fishing biocomplexity project which performs collaborative research with
local fishermen groups. Provided algorithms for use in the operational
product stream for the SeaWiFS and MODIS missions and regularly assist project
staff. Conduct a field program (Plumes and Blooms) that gives ~10
undergraduate students the opportunity to go on a research cruise each
year.
