Storm induced water mixing?

Further study calls for cooperation:• Seismology• Oceanography• Borehole hydrology• WaveWatch III model

Non obvious applications:• Monitor climate change

– History– Decay of Antarctic ice

What is needed?

Time-series data that is…

• continuous over long periods of time– filling gaps

• carefully decimated for download– not mean values

• can be processed without downloading– Oceans 2.0
