Paths of the transmitting and receiving glider along New Jersey, Delaware, and Maryland coasts. The gliders transited very similar paths, but were not always close together. Dark gray regions indicate when the gliders were within 1.3 km of each other within study boxes, and red dots indicate when the receiving glider detected the transmitting glider. The diamonds are the location of NDBC buoys used to determine wind speeds. Dashed boxes indicate the three regions the receiving glider detected the transmitting glider
