Use of floating surface detector stations for the calibration of a
  deep-sea neutrino telescope
  We propose the operation of floating Extensive Air Shower (EAS) detector
stations in coincidence with the KM3NeT Mediterranean deep-sea neutrino
telescope to determine the absolute position and orientation of the underwater
detector and to investigate possible systematic angular errors. We evaluate the
accuracy of the proposed calibration strategies using a detailed simulation of
the EAS and KM3NeT detectors.
