Scientists are working to pinpoint the ocean’s last quiet places — and hush certain loud ones.
National Geographic’s Pristine Seas project“The world’s last quiet oceans also tend to be places free from fishing pressure, pollution, or invasive species. Mapping acoustics is one way to pinpoint high-quality marine habitat,” Williams says.In the Pacific Northwest, Williams and his colleagues have used underwater acoustic maps to protect key habitats for orca whales. Since orcas are group-hunting predators who communicate to locate and ambush prey, noise pollution can starve them.
These maps helped local communities and policy-makers in British Columbia create sound sanctuaries near beaches where northern resident orcas congregate. Plus, the Port of Vancouverto reduce noise through the ECHO Program, such as reimbursing vessels for the extra transit time. Underwater acoustic maps may also inspire similar policies to protect the southern resident orcas that live in Haro Strait, which sits between Vancouver Island and Washington State. This group of whales is critically endangered — only 74 individuals remain. Williams has demonstrated that southern residentThis spring, Washington state's government approved funding for, a collaborative program aimed at reducing large commercial vessels’ disturbances to killer whales.
“Silence really is golden,” Williams says. “We are running out of time to protect the last acoustic refuges in the ocean.”
