New Technology Will Listen For Underwater Whale Traffic In An Effort To Reduce Ship Strikes
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.
Underwater robots swarm the ocean
Researchers test a new, acoustic-based navigation system to solve a problem that oceanographers have grappled with for years—getting multiple underwater robots to monitor the ocean cooperatively in swarm-like fashion.

Read MoreGroups of Pilot Whales Have Their Own Dialects
In humans, different social groups, cities, or regions often have distinct accents and dialects. Those vocal traits are not unique to us, however. A new study from the Woods Hole Oceanographic Institution (WHOI) has found that short-finned pilot whales living off the coast of Hawai’i have their own sorts of vocal dialects, a discovery that may help researchers understand the whales’ complex social structure.
Read MoreCoral Larvae Use Sound to Find a Home on the Reef
Choosing a place to call home is one of the most consequential choices a coral can make. In the animal’s larval stage, it floats freely in the ocean, but once it settles down, it anchors itself permanently to the rocky substrate of a reef, and remains stuck there for the rest of its life. Exactly how these larvae choose a specific place to live, however, is largely unclear.

The twilight zone is a part of the ocean 660 to 3,300 feet below the surface, where little sunlight can reach. It is deep and dark and cold, and the pressures there are enormous. Despite these challenging conditions, the twilight zone teems with life that helps support the ocean’s food web and is intertwined with Earth’s climate. Some countries are gearing up to exploit twilight zone fisheries, with unknown impacts for marine ecosystems and global climate. Scientists and engineers at Woods Hole Oceanographic Institution are poised to explore and investigate this hidden frontier.
