Ocean Circulation and Dynamics, Ocean’s Role in Climate

My overall research interest is the fundamental understanding of the physics of the basin-scale ocean and its role in Earth’s climate. I am involved in improving estimates of the geophysical state of the ocean circulation through analysis of field data and circulation model results. The subpolar North Atlantic and Arctic Ocean ventilation process (rates, pathways, variability, and mechanisms) interest me in particular. High latitude physical oceanography, in both hemispheres, is another research theme. I also investigate key physical processes that maintain the state of the global upper ocean focusing on fluid dynamics and thermodynamics and their role in controlling sea surface temperature variability over years to decades. These are all examples of rotating stratified fluid dynamics, an amazing and beautiful subject.

Knowledge of these processes is vital if we are to describe and understand climatic fluctuations on time-scales of years to decades. At these low frequencies we know that the ocean and atmosphere interact as a coupled system. Understanding low frequency natural climate perturbations is clearly a problem of special current relevance. Further, explaining natural climate variability is a prerequisite of addressing mankind’s effect on global climate.

Moreover, this understanding guides our thinking about other oceans in time and space. Recent discoveries of extra-terrestrial oceans in our solar system and recognition of how much Earth’s ocean has changed in the past, galvanizes me to think about the role of oceans in planetary system dynamics writ large.

Miguel Jimenez-Urias seminar

Miguel gave a great seminar in our Atmospheres & Oceans discussion group last week. He discussed his PhD thesis research on the dynamics of flow across the Greenland-Scotland Ridge. You can watch it here!

OC3D review

Leon Vlieger has written a review of Ocean Circulation in Three Dimensions.

Congratulations Dr. Almansi!


Mattia Almansi presented and defended his PhD thesis yesterday. His thesis title is “Denmark Strait Ocean Circulation Variability.” The presentation and discussion was online with participants in Europe and the US. Mattia himself was alone in an AirBnB in Southampton, UK (where he will start his postdoc next week). Under these challenging circumstances, Mattia did… Read more »
