Humpback whale songs provide insight to population changes
Following reports of unusually low whale numbers that began in 2015-16, researchers at the University of Hawaii in collaboration with the Hawaiian Islands Humpback Whale National Marine Sanctuary, Oceanwide Science Institute and Woods Hole Oceanographic Institution, examined song chorusing recorded through long-term passive acoustic monitoring at six sites off Maui.
Sea Ahead
The game-changing technologies that will transform our ability to understand and manage Earth’s last great frontier. Monitoring instruments—and ocean technologies in general—have come a long way. We now have Artificial Intelligence (AI)-enabled robots that not only allow researchers to access the most remote spots in the ocean, but can decide where to explore once they get there.
Acoustics of the deep sea tell us about biodiversity
Some researchers are working to improve current listening technology. At the Woods Hole Oceanographic Institution in Woods Hole, Massachusetts, Ying-Tsong Lin is building a starfish-shaped contraption of hydrophones that can tune into certain sounds hundreds of miles away, like a telescope for sound.
Could listening to the deep sea help save it?
A recent New York Times article about sound in the deep ocean briefly mentions the work by Woods Hole Oceanographic Institution (WHOI) acoustic scientist Ying-Tsong “YT” Lin and his work developing an “acoustic telescope.”

In a bid to reduce the number of whale deaths, researchers Woods Hole Oceanographic Institution and collaborators worked together to develop Whale Safe, a new detection system provides mariners with up to date information about whales present in shipping lanes.
Listening to fish with passive acoustics
Scientists at the Woods Hole Oceanographic Institution and NOAA Fisheries combine forces to adapt technologies used to detect marine mammals for fisheries management.

Though they make their homes among the raucous cliffs framing the Atlantic, puffin are still sensitive to the activities of humans. WHOI biologist Aran Mooney explains why being conscious of our sound footprints might help with their conservation

The International Fund for Animal Welfare (IFAW) and its Marine Mammal Rescue Team in Yarmouth, Mass. have responded to a record high of more than 464 marine mammals stranded on Cape Cod since January this year. Researchers at Woods Hole Oceanographic Institution (WHOI) believe patterns from animal sound data may be the key to curbing these numbers.

Scientists from the Benioff Ocean Initiative and Woods Hole Oceanographic Institution have deployed a a hydrophone, or underwater microphone, to listen for whale traffic in the Santa Barbara Channel. They hope to use the microphone to help prevent collisions between whales and boats – which are often deadly to whales.
