Ice Drift in Robeson Channel as Determined Using Television Moving Target Circuitry.
The movement of ice floes in Robeson Channel was followed over a one-week period during August 1973 using television moving-target circuitry from a cliffside base 350 m above sea level. The basis of the method was to subtract a current TV picture from a video tape recording of the same scene made so...
