Principal electronics technician David Havens turns the wheel which adjusts vertical angle on the new satellite weather antenna, state of the art antenna for its time, installed aboard D/V Glomar Challenger (ship) during the port call at Agana, Guam, between Legs 59 and 60 of the Deep Sea Drilling Project. The big wheel at the bottom takes care of the horizontal angle. Shipboard data tables are provided for the required horizontal and vertical antenna angles. Information is received from a satellite in stationary orbit and processed by shipboard equipment to produce a weather map which enables the captain, scientists and operations personnel to get weather forecasts 18 hours in advance at any drilling and coring site. 1978
