Breakthrough: Minke Whales Proven to Hear Ultrasonic Frequencies

For the first time, researchers have captured baleen whales to study their hearing, revealing that minke whales can hear at higher frequencies than previously thought. This discovery, published in Science, suggests that these whales may use ultrasonic hearing to avoid predators like killer whales. The study, which involved capturing and testing two juvenile minke whales off Norway, has sparked controversy over potential stress and harm to the animals. The findings could influence regulations on ocean noise, as high-frequency sounds from human activities may impact whale behavior and health.

Using Ocean Noise to Monitor Kīlauea Volcano

Scientists at the Hawaiian Volcano Observatory are using ocean noise velocity as a tool to monitor volcanic activity at Kīlauea volcano. Changes in the velocity of ocean noise signals can indicate the opening and closing of fracture systems caused by magma movement beneath the surface. By analyzing these velocity changes, scientists can gain insights into the behavior of the volcano and potentially forecast volcanic activity. This technique is being developed for real-time monitoring at Kīlauea and Mauna Loa volcanoes.
