According to scientists at the Monterey Bay Aquarium Research Institute (MBARI), sperm whales frequent the deep waters around Monterey Bay much more than previously thought. The researchers analyzed seven years' worth of recordings captured by an underwater microphone near Monterey Bay to see how often they heard clicks made by sperm whales.
This study 'allows us to recognize they're a persistent part of the biodiversity here,' he says. 'We did not know that. We didn't know it from our eyeballs.'
This finding is important for conserving sperm whales, Oestreich says. 'This is an endangered population of marine mammals. If we want to protect them, we need to gather more data and understand their patterns better.'
