This week, Alex’s sibling robot, Mercury, battled directly through Hurricane Sandy 160 km due east of Toms River, NJ, and the now-decimated Jersey Shore. It met the storm at the point labeled 110 in the map below and traveled with the hurricane to the point labeled 100.
The wave-powered robot transmitted weather data in real time, recording a plunge in barometric pressure of over 54.3 millibars to a low of 946 millibars as Sandy approached the coast. (Typically, atmospheric pressure at sealevel is 1013 millibars). It clocked winds at up to 70 knots, or 130 km/hour.
