Getting your Feet Wet - Why seismologists acquire simultaneous onshore/offshore data

Most major plate boundaries (with a few notable exceptions, can you think of which they are?) sit either completely offshore (i.e. mid-ocean ridges) or at the junction between an ocean and a continental land mass (i.e. subduction zones).  Thus to study the forces that control plate tectonics we commonly have to jump in and "get our feet wet" - i.e. go into the oceans. As seismologists we routinely get our feet wet by deploying ocean-bottom seismometers (OBS) to record ground motions both from near and far earthquakes as well as man-made sources.
