Many in situ measurements at sea are made using instruments tethered to a ship with an electromechanical cable. As the ship moves in response to the surface waves, the supporting cable transmits the motion to the instrument. This ship-induced motion is a source of error in the measurements and is a source of mechanical failure that has led to the loss of instruments.
