A survey apparatus 17 comprises a buoy 1 tethered to a mooring 3 on the sea bed by an umbilical 2. A power system (Fig-2, 7) is contained within the buoy. The umbilical comprises a structural member and electrical cabling, wherein the structural member forms the tether connecting the buoy to the mooring (Fig-3, 14) and the cabling (Fig-3, 16) provides communication and power to bottom mounted sensors (Fig-3, 13). A radio transmitter (Fig-2, 12) allows communication of collected data to a receiver located onshore. It may be that the floating arrangement for the buoy may comprise a mono-hull or a catamaran or a small water-plane area twin hull. There may be an onboard generation unit harnessing the power of the sun, tidal currents or waves to recharge on board energy storage. Further sensors may be used for collecting environmental data. The radio transmitter may provide real time communication of data collected to a receiver and may also provide remote control of the survey apparatus from shore. |
