In this undated photo provided by the New England Aquarium in May 2019, Dr. Rosalind Rolland, Director of Ocean Health and a Senior Scientist in the Research Department at the New England Aquarium in Boston, poses on a boat next to a southern right whale taken during an expedition to the Auckland Islands, an archipelago of New Zealand. Whale researchers in New England say they’ve found a new way to measure the amount of stress felt by giant whales, and the technique could help protect the massive sea creatures.
