Helping Ships Avoid Endangered Whales

The world's last 350 North Atlantic right whales live along the East Coast. Collisions with ships are a deadly hazard, but new listening buoys are helping. Here's how.

Right whale detections: last 24 hours

New smart buoys listen for whale calls all day, every day. Frequent alerts let ship captains know where and when to slow down--and save a whale.

The green dots on this map show locations of buoys listening for endangered right whales. If you see a red whale icon instead, it means a buoy at that location has heard a right whale within the last 24 hours. This information is made available to ship captains, who can slow to 10 knots and post a lookout to avoid a collision.

Note: Right whales often leave Massachusetts Bay in spring. If you don't see any whale detections here, see this archived map from April 2008.
