Whale in the shipping lanes!
A whale is swimming near the shipping lanes, occasionally making "up-calls" to stay in touch with other whales in the area. Captains of large, fast-moving ships often can't see them in time to avoid collisions.
New auto-detection buoys installed in some shipping lanes monitor the water for right whale calls 24 hours per day. Calls from whales within 5 nautical miles are loud enough to be recorded on the buoy’s hydrophone, mounted 60 to 120 feet beneath the surface.
