1. A sensor system for use in an underwater environment, the system comprising:

  • a surface buoy configured to be disposed at a surface location on a water body,an underwater sensor connected to the surface buoy,a stretchable hose having a characteristic stretch extension selected to accommodate a predicted vertical heave of the surface buoy, the stretchable hose being attached to the surface buoy, for connecting the sensor to the surface buoy, the stretchable hose comprising;

    at least one conductor disposed in a sidewall of the hose, anda hose coupling attached to one end of the stretchable hose, wherein the hose coupling is configured to allow the at least one conductor to pass from the sidewall of the stretchable hose through the hose coupling to an external interface without exposure to water, andan anchoring member connected to the sensor,wherein, in response to vertical heave of the surface buoy at the surface location on the water body, a length of the stretchable hose adjusts to thereby maintain the sensor at a predetermined depth in the water body.
