flowWeaver

More information

flowWeaver is an interactive tool for exploring transport and connectivity patterns in high-resolution ocean models such as ROMS. The initial application (in version 0.4.3) contains two weeks of Salish Sea and Pacific Northwest coastal circulation during summer 2005. The underlying ocean model is MoSSea (Modeling the Salish Sea).

Future versions will contain much longer timespans, as well as more explicit instructions for making flowWeaver work with your favorite circulation model.

 

Hover over the map to see the path that water at the surface (orange) and at depth (3/4 of the way to the bottom: red) will take over the next 14 days...

Exploring the enlargement of Puget Sound shows the average tendency of deep water to move landward and surface water to move seaward, as well as lots of additional complexities.

flowWeaver is written in Java using the Processing toolkit. It relies on an intensive, custom particle-tracking analysis of the underlying ROMS simulation, saved as a series of "flowmap" files. Contact me if you would like to see the Java code that I use to generate these.
