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 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.
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
Kelp Remote Sensing using SPOT Imagery - New work using SPOT multispectral imagery to assess the dynamics of kelp forests in the northern Southern California Bight - Couples to the SCB-LTER below. NASA - with Stephane Maritorena, Steve Gaines, Phaedon Kyriakidis, Brian Kinlan & Dick Zimmerman (ODU)
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
Bermuda BioOptics Project (BBOP) - Ocean color investigations of the Sargasso Sea - NASA - Led by Norm Nelson
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
Eddies Dynamics, Mixing, Export and Species composition (EDDIES) - Field / satellite data effort to assess the importance of mesoscale eddies to the biogeochemistry of the Sargasso Sea - NSF - Led by Dennis McGillicuddy (WHOI)
Vertical Transport in the Global Ocean (VERTIGO) - Field effort to analyze the export of particulate carbon from the upper ocean and its cycling in the mesopelagic - NSF/DOE - Led by Ken Buesseler (WHOI)
SPOT - Provides deeply discounted SPOT imagery of US and Canada to other US universities (www.spot.ucsb.edu). The program also provides nearly free SPOT imagery to UCSB researchers and students (www.icess.ucsb.edu). I am the director of the center.
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 2007). Class web site is available here.
