23. Elephant Seals Can Be Scientists Too

Elephant seals collect data beneath the Southern Ocean. Dr. Clive McMahon explains how researchers equip southern elephant seals with miniature conductivity, temperature, and depth sensors. As the seals dive and travel through remote waters that are difficult to observe, especially during winter, the animal-borne sensors collect information about temperature, salinity, depth, and ocean productivity before transmitting observations by satellite. The data help scientists study elephant seal tracking, foraging, body condition, and population change while improving Southern Ocean monitoring. They also reveal physical processes connected to Antarctic dense water, global ocean circulation, weather, and climate.Episode Guest: Dr. Clive McMahonReview the research publication discussed in the episode hereVisit Dr. McMahon’s publications on Google Scholar Visit the website of the Sydney Institute of Marine SciencesEpisode Transcript and more information on the Pine Forest Media WebsiteFollow Pine Forest Media on Instagram @pineforestmediaHosted, produced, written, and edited by Clark Marchese Cover art and PFM logo by Laurel Wong. Theme music by Nela RuizFind some more Pine Forest Media podcasts belowListen to Oceanography on Spotify or Apple PodcastsListen to Plastic Podcast on Spotify or Apple PodcastsListen to Something in the Water on Spotify or Apple Podcasts Hosted on Acast.
