Short summary
Oceanic turbulence can be measured from autonomous vehicles such as floats and gliders. The raw data files, however, are too large to be transmitted back via satellite. Some processing to reduce the data must happen on board. We present a scheme to do just that and test it with existing measurements. Our scheme will make it possible to deploy turbulence platforms without the need for their recovery.
