Seismic noise in Arizona
DF microseisms• non-linear interaction of opposing wave fields
SF microseisms• Wind waves interacting with coast
Earth‘s hum• Normal modes of earth• Infragravity waves

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
