SEA CURRENT RADAR TO HELP IN SHETLAND TANKER DISASTER CLEAN-UP

 LONDON, Jan. 8 /PRNewswire/ -- A sophisticated radar system, which should allow the pollution control authorities on the Shetland Islands to pre-empt the spread of the oil slick in the North Sea, is being hurried to the Islands.
 Marconi Radar and Control Systems and Wimpey Environmental will install the Ocean Surface Current Radar (OSCR) system on the Island, providing vital information about tidal movements around the coast.
 Scientists can use the data from the OSCR system to predict the spread of the oil slick and take preventative action to minimize the environmental damage caused by the MV 'Braer' disaster.
 The radar system works regardless of the weather conditions, which have so far hampered the salvage effort.
 The equipment is being transferred to Scotland and the two companies plan to have it up and running on Monday, Jan. 11.
 The system, developed originally for the military market and operating in the HF frequency band, monitors the wave patterns on the surface of the water. It will provide a continual update on the movement of the slick to the environmental authorities.
 Two radars are being deployed in order to provide accurate water speed and direction vectors, which are updated every 20 minutes, night and day.
 It is believed to be the first time that this technology has been used in a major oil spillage.
 Technical Note.
 The OSCRs, jointly developed by Marconi Radar and Control Systems and Marex Technology, utilize the principles of surface wave HF technology. This involves the signal following the surface of the water and bending with the earth's curvature. These signals are reflected back by the waves and then processed to provide calculations of the actual sea currents.
