A study by MBARI researchers and their collaborators published today in Ecology Letters sheds new light on the movements of mysterious, endangered blue whales. The research team used a directional hydrophone on MBARI’s underwater observatory, integrated with other advanced technologies, to listen for the booming vocalizations of blue whales. They used these sounds to track the movements […]
![Clarifying the chaos of narwhals behavior; what are narwhals, how they help [Details]](https://i0.wp.com/indiainternationaltimes.com/wp-content/uploads/2022/09/narwhals.png?fit=700%2C471&ssl=1 "narwhals")
Researchers have used the mathematical equations of chaos theory to analyse the data from long-term monitoring of an electronically tagged narwhal. They have extracted previously undetected diurnal patterns within what initially appeared to be irregular diving and surface resting behavior, using records extending across 83 days. “While animal-borne ocean sensors continue to advance and collect […]
Using sophisticated electronic tags, scientists have assembled a large biologging dataset to garner comparative insights on how sharks, rays, and skates – also known as “elasmobranchs” – use the ocean depths. While some species spend their entire lives in shallow waters close to our shores on the continental shelf, others plunge hundreds of meters or […]
Ocean acidification will severely impair coral reef growth before the end of the century if carbon dioxide emissions continue unchecked, said new research on Australia’s Great Barrier Reef led by Carnegie’s Ken Caldeira and the California Academy of Sciences’ Rebecca Albright. Their work, published in Nature, represents the first ocean acidification experiment in which seawater […]
