Scientists eavesdrop on minke whale ‘boing’ calls in Hawai’i, and 4 other articles you don’t want to miss

By Angharad Brewer Gillham, Frontiers science writer Image: Annie Leblanc/Shutterstock.com At Frontiers, we bring some of the world’s best research to a global audience. But with tens of thousands of articles published each year, many often fly under the radar. Here are just five amazing papers you may have missed. Scientists eavesdrop on minke whale conversations in Hawai’i Scientists writing in Frontiers in Marine Science used hydrophones to study hard-to-spot minke whales in Hawai’i, learning that they use their ‘boing’ calls more frequently when they are close to other members of the same species. Minke whales who visit this area are hard to study because they are small, solitary, and visit outside the times when most ship-based surveys are conducted. Passive acoustic monitoring, using hydrophones mounted on the sea bed, allows scientists to listen in on whales all year round. The authors used 47 hydrophones to record thousands of calls between 2012 and 2017. These calls were analyzed to detect individual whales and monitor their behavior in the study area. The minke whales used their ‘boing’ calls only between fall and spring, and called more rapidly when other minke whales were nearby. Because minke whales are so enigmatic, it isn’t […]
