Ocean Dynamics @ St Andrews

About Us

This site is under active construction — content and visuals may change.

The Ocean Dynamics group at the University of St Andrews studies the ocean from the beautiful coastal town of St Andrews, in Scotland. We're based in the School of Earth and Environmental Sciences and participate as part of COASt (Climate, Oceans, and Atmosphere @ St Andrews). You can find lots of technical info about our group on our wiki page, or scroll on to learn more about our research, team members, and recent news!

Our Research

Physical and biogeochemical dynamics of the polar oceans

Explorations of processes shaping polar ocean circulation, mixing, and tracer transformation from mesoscale to microscale.

Ocean predictability and change

Quantifying predictability across time scales and diagnosing ocean responses to climate forcing and variability.

Climate dynamics and the oceans

Interactions between the global climate system and ocean circulation, heat and carbon uptake, and feedbacks.
