The first hearing tests on a wild population of healthy marine mammals revealed that beluga whales in Bristol Bay, AK, have sensitive hearing abilities and far less extensive hearing losses than scientists anticipated. At a time when noise in the ocean is increasing from human activities, understanding the natural hearing abilities of whales and other endangered marine mammals is crucial to assessing potential noise impacts on animals, says WHOI biologist Aran Mooney, who led the auditory testing. Researchers also gave the animals physical exams to assess their overall health, and obtained skin, breath, and blood samples. Satellite transmitters were attached to some of the whales before release to study the whales movements. All work conducted under NMFS permit no. 14245.
Caption from WHOI News Release dated 06/20/2018:
In addition to the auditory testing, the researchers also performed a physical exam to assess the overall health, sex, and estimated age of each animal and obtained skin, breath, and blood samples to collect information on the whales hormone levels, microbiome bacteria, and other health-related data. Satellite transmitters were attached to some of the whales before release to study the whales movements. All work conducted under NMFS permit no. 14245.
