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 bit dated…) include:

EXPORTS – The EXport Processes in the Ocean from RemoTe Sensing (EXPORTS) project is a planned major field effort supported by the NASA Earth Science Division to predict the export and fate of ocean Net Primary Production (NPP) from satellite and other observations. I am presently the Chair of the Science Definition Team tasked with developing its Implementation Plan.   

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). 

Global CDOM - Global surveying & characterization of the chromophoric dissolved organic matter pool as part of the CLIVAR Repeat Hydrography Survey - NSF / NASA - with Norm Nelson and Craig Carlson

Plumes and Blooms (PnB) - Ocean color investigations of the Santa Barbara Channel - NASA - with Stephane Maritorena

Santa Barbara Coastal Long-Term Ecological Research site (SBC-LTER) - Focuses on the drivers of change in kelp ecosystem off Santa Barbara - Led by Dan Reed

Kelp Remote Sensing using High Resolution Satellite Imagery - New work using high spatial resolution multi-spectral imagery (SPOT & Landsat) to assess the dynamics of kelp forests in the northern Southern California Bight - Couples to the SCB-LTER.  NASA - with Dan Reed and others

Bermuda BioOptics Project (BBOP) - Ocean color investigations of the Sargasso Sea - NASA - Led by Norm Nelson

Flow, Fish & Fishing (F3) - Modeling project to assess the role of uncertainty in fishery management patterned after the nearshore fisheries of California - NSF - with Chris Costello, Steve Gaines, Ray Hilborn, Bruce Kendall, Steve Polasky, Bob Warner and Kraig Winters

My Teaching:

I presently have a 5/6 time teaching release due to my administrative obligations to ERI and IGPMS.  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: Introduction to Marine Resources

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 the winter of 2014).  Class web site is available here
