Tracers & Transport Diagnostics

We aim to identify and understand the tracer-independent transport information contained in ocean tracer data. With collaborators, I have developed some new, powerful theoretical tools. Applications include:

  • Diagnosing transport timescales and water-mass composition in the North Atlantic ocean.
  • Estimating the oceanic burden of anthropogenic carbon—the new methods have distinct advantages.
  • Diagnosing and understanding the dynamics of sea-surface anomalies in temperature, salinity, height, and colour.
  • Interpreting time-lagged correlations from oceanographic timeseries data.

I work on this topic with Aleksi Nummelin, Anand Gnanadesikan, and Darryn Waugh.
