Timothy DevriesThe circulation of the ocean plays a major role in controlling Earth’s climate, but most global ocean circulation models have significant errors and biases, making their predictions suspect. This talk presents a way to correct these biases by assimilating large spatial datasets of oceanographic observations into a global ocean circulation model. I will discuss what observations can be used to correct model biases, how these are assimilated into the model, and give some examples of how the data-assimilated model can be applied to simulate ocean processes.

Bio: Timothy received his PhD at UC Irvine in Earth System Science in 2010, and completed his postdoctoral training at UCLA. Since 2014, he has been an Assistant Professor in the Geography Department at UCSB. His research interests include the ocean’s role in the global carbon cycle, the cycling of nutrients and trace metals in the ocean, and ocean heat uptake. His research tools include numerical models, data assimilation, probabilistic models, and machine learning.

The objectives of the ThinkSpatial brown-bag presentations are to exchange ideas about spatial perspectives in research and teaching, to broaden communication and cooperation across disciplines among faculty and graduate students, and to encourage the sharing of tools and concepts.

Please contact Werner Kuhn ( to review and schedule possible discussion topics or presentations that share your disciplinary interest in spatial thinking.
