Analysis

Active

Two remotely operated wave gliders are operating and transiting on the East Scotian Slope. C34167NS is transiting from 43 34.410 N 060 13.232 W via three listed waypoints; C34164NS is copper-coloured with a 1.2 m mast, white light, orange flag and non-transmitting AIS receiver. Both are small, slow-moving unmanned surface vehicles (about 1.2 knots); mariners should navigate with caution and contact the numbers provided for further information. This message cancels NW-M-1522-26.

Navigate with caution, keep clear of the wave gliders and contact the operators for information or to report sightings.
