Measurement techniques

   
 
 

A variety of different measurement techniques is employed at the BSH. During ship based experiments electronic devices are used which can be lowered through the water column on wires or can be towed behind a moving ship.  Moorings and platforms have the advantage that measurements can be performed over longer time periods at a fixed position. Usually, the data are stored within the instrument and will be down-loaded after the recovery of the instruments. Deep drifters also operate in an internal registration mode. They are not fixed to one position but drift passively through the oceans carried along by the ocean currents. Satellites and air planes allow a remote sensing of the ocean and deliver information on the physical state of the sea surface.
