Bruce ran a Collaborative Ocean Visualization Environment (COVE) M2 tides visualization tutorial to build upon the COVE experience from last class.

M2 tides are the components of tide that come from the unique shape of the bottom of the ocean (the bathymetry). M2 tides are identified with help from remote sensing by satellite.

Two-dimensional images were created for publication from statistical methods over 20 years of data globally. Geographical data appears less skewed on a virtual globe.

The volume of data supporting M2 visualization is extensive in volume, but simple in format:

Latitude Longitude Magnitude triples for each location on earth for one timestep per file (timesteps are approximately an hour apart in our tutorial data).

COVE describes visualizations via a COVE Markup Language (COVEML). The M2 tides markup drives the visualization seen here:



Bruce demonstrated how to use the interactive tools to make changes to the visualization, as well as how to navigate a visualization that is active in the COVE software:



Images generated by COVE can be stitched into a movie format.
