Out of one, many: creating broadband spectra of oceanic internal waves

Welcome to our final Edinburgh Flow Dynamics Group event of the term. We are honored to have Professor Oliver Bühler, a Professor of Mathematics and Atmosphere Ocean Science at the Courant Institute of Mathematical Sciences at New York University, as our guest speaker today.

Professor Bühler completed his PhD in applied Mathematics at Cambridge before lecturing at the University of Saint Andrews and eventually moving to New York in 2002. He will be sharing his expertise on internal waves with us today.

The research discussed today was a collaborative effort involving Ryan Du, a PhD student at the Courant Institute, and participants from an interdisciplinary program in Atmospheric Science and Mathematics. We are also keen on attracting undergraduate applicants from Europe, particularly those with a background in Mathematics.

The project also involved Sylvia, an undergraduate student who gained research experience through this work, and Michal Shavit, a postdoc funded by the Simons Foundation. Additionally, Jalal Shatah, a colleague funded by the same foundation, played a significant role in this project.

The presentation will focus on creating broadband spectra of oceanic internal waves. Professor Bühler will provide an overview of broadband observations in the ocean and discuss theories related to this topic. The main part of the talk will delve into abstract wave turbulence, four wave dual cascades, and recent findings in this area.
