PS007:
Transport and Coherent Structures: New and Traditional Approaches for Studying Ocean Stirring and Mixing


Session ID#: 27979

Session Description:
Ocean flows are dominated by coherent structures, like eddies, with lifetimes longer than typical dynamical timescales. Due to their capacity to transport water and material over long distances, these features play an important role in climate, biogeochemistry, and small-scale mixing. Recently, there has been an influx of powerful techniques from the mathematical literature for identifying coherent structures in ocean flows. These include ideas focussed on Lagrangian flow maps, dynamical systems theory, and set-theoretic approaches involving transfer functions and clustering. 

There remain many questions about how these novel ideas are related to traditional metrics of ocean mixing. For example, how can coherent structures improve eddy parameterizations in ocean models? How do sparse sampling, noise, and smoothing impact the identification of coherent structures, which frequently requires the full flow? How can we exploit novel observational approaches such as autonomous robots, clustered drifter releases, or remote sensing? 

We invite contributions on transport and coherent structures, including new Eulerian and Lagrangian approaches, numerical modeling studies, observational error assessments, and applications to problems in ocean physics and biogeochemistry. Our hope is to engage a broad swath of the community to help bring these methods to bear on important contemporary problems in oceanography.
