Ocean dispersal (coming soon)

Computation of the spatial distribution of a tracer over time across the ocean, using an ocean general circulation model. This may be used to predict the dispersal of planktonic larvae or the spread of dissolved pollutants. The client provides tracer source locations and durations.

This analysis begins with the specification of one or more tracer point sources in the ocean, defined by geographic coordinates. Each source may be a one-time source (e.g., representing a single spill event), a continuous source of indefinite duration (e.g., a leaking underwater pipeline) or a continuous source of limited duration. We then compute the evolution of the tracer's distribution across the global ocean over time attributable to the specified sources. Main deliverables are:

• A file in netCDF or TSV format, listing the concentration of the tracer at each grid point and at each time point. One can choose between hourly, daily or monthly resolution.
• Basic visualizations of the tracer's distribution over time (contour plots).

In addition, we also provide a thorough Materials & Methods writeup for use in your publications.
