a Wind velocities at the NDBC buoys during the deployment. Sigma (density-1000) cross section of the receiving (b) and transmitting (c) glider. Points indicate the depth of the receiving glider (red) and transmitting glider (white) when detections were recorded. Gray bars indicate when the gliders were within 1.3 km of each other
