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.

Or, to quote the visionary polymath Alexander von Humboldt (1769–1859):

It is the duty of philosophers to determine and adjust their various elements, according to the sublime model of astronomical science, in order that some of those eternal laws may be made known by which the climatic changes of the firmament are dependent on the liquid and aerial currents of our planet.

Atousa’s Reflections on Teaching

Atousa Saberi has published a blog post on her experience teaching an undergraduate class for the first time. She was supported by a Dean’s Teaching Fellowship in Fall 2020 and taught Natural Hazards. Great work Atousa!

Nordic Seas Heat and Salt Redistribution

Nordic Seas Heat and Salt Redistribution

Collaborator Mike Spall has published a paper in Progress in Oceanography with Mattia Almansi and Tom. The paper shows that the dominant exchange between within the Nordic Seas is an export of warm, salty water from the Norwegian Sea into the Greenland and Iceland Seas, with both the mean cyclonic boundary current system and eddy […]

Ali Siddiqui in action at sea

Ali is participating in the 2021 GO-SHIP A22 expedition on the R/V Thompson to the western North Atlantic Ocean. He’s a CTD watch stander and working with the LADCP. Here, he’s in action with a sofar spotter metocean buoy. It may look like he threw it over the side, but in fact he’s using Jedi […]

New cyber-infrastructure project funded

New cyber-infrastructure project funded

Tom is Co-PI on a new NSF cyber-infrastructure project. The project will build a public data-base of fluid dynamics simulations, including submesoscale ocean circulation (for example, Langmuir turbulence, as depicted, from co-PI Sullivan et al. 2012). The team is led by Charles Meneveau, with Hopkins, Georgia Tech, and NCAR collaborators. Read about the project here.
