Dolphins Assist Scientists Studying Effects of Data-logging Tags

For scientists studying marine mammals in the wild, data-logging tags are invaluable tools that allow them to observe animals’ movements and behaviors that are otherwise hidden beneath the waves much of the time. The tags, which temporarily attach to animals using suction, record sounds and gather information about animals’ pitch, speed, and depth. But what effect do the tags have on the animals?

Researchers from Woods Hole Oceanographic Institution (WHOI) and Texas A&M University-Corpus Christi (TAMUCC) are working with dolphins and their trainers at Dolphin Quest at The Kahala Hotel and Resort in Oahu to answer that question, among others. (more…)

New research sheds light on how porpoises hear in one of the world’s busiest rivers

The Yangtze finless porpoise, which inhabits the high-traffic waters near the Three Gorges Dam in China, is highly endangered, with only about 1,000 animals alive today. Scientists from Woods Hole Oceanographic Institution (WHOI) and their Chinese colleagues are using medical technology to shed new light on this species’ critical sense of hearing in a waterway punctuated by constant shipping, dredging, and underwater construction.

“We want to understand how they may be impacted by noise,” said Aran Mooney, a biologist at the Woods Hole Oceanographic Institution (WHOI) and a lead author on the study published online this week in the Journal of Experimental Biology. (more…)
