Numerical ocean circulation models are getting more and more realistic, but tools to analyze the model output are still primitive. We are using our seed fund award to develop a prototype environment that will make ocean-model output analysis easy, fast, and (eventually) accessible to the general public. We envision tools to enable on-the-fly analysis of ocean-model output on a computer cluster. They will advance the post-processing of ocean model output, which will in turn increase its scientific value.

Over the past few months we have improved the implementation of our in-house numerical particle tracking algorithm, which enables a Lagrangian (drifting in space) analysis of the Eulerian (fixed in space) model output. Substantial speedup has been achieved with these improvements, as reported by Gelderloos et al. (2016a). The improvements will enable particle tracking in global high-resolution model solutions over several years, whereas the studies are now limited to regional configurations and a time span of weeks to months.
