Oceanographic and Atmospheric Processes

The ocean is a vast, turbulent system that redistributes heat, carbon, and nutrients across the planet, shaping climate on timescales from days to millennia. Oceanographers study how water moves at scales ranging from basin-wide circulation driven by wind and density gradients, down to short-lived submesoscale eddies only kilometers across, using a combination of satellite observations, in-situ measurements, and numerical models that must faithfully represent all of these interacting processes. A central challenge is understanding how energy cascades across these scales — for instance, how small mixing events in the ocean's surface layer ultimately influence global heat transport — and how best to incorporate sparse real-world data into models through data assimilation to improve both hindcasts and predictions. As the climate changes and the ocean absorbs more heat and freshwater, open questions about shifting circulation patterns, altered eddy dynamics, and the future stability of large-scale overturning currents remain among the most consequential problems in Earth science.
