What Does It Take to Break a Whale?

MIT/WHOI graduate student Regina Campbell-Malone put a 493-pound, 14-foot whale jawbone through a series of stress tests to assess the amount of force required to break whale bones. Campbell-Malone, advisor Michael Moore, and other marine biologists have been trying to gather data that can help regulators create new shipping speed limits that could help prevent collisions between whales and vessels.
