What is the Ocean Twilight Zone (and How to Protect It) with Chris Dorsett

from Oceanography

What is the Ocean Twilight Zone? Explore the mesopelagic (200–1000 m) and why it’s central to climate, fisheries, and biodiversity. Ocean Conservancy’s Chris Dorsett explains daily vertical migrations, lanternfish and vampire squid, and the biological carbon pump that shuttles carbon to the deep. We unpack emerging pressures—industrial harvest for fishmeal/fish oil, deep-sea mining plumes, and marine carbon-removal trials—and how science-based policy can safeguard this ecosystem before impacts stack up. Clear, accessible ocean science plus practical context on precautionary management make this a go-to primer for anyone curious about how mid-water life supports whales, tunas, and the health of our seas.Support our science communication by joining us on Patreon or sending us a gift on PayPalEpisode Guest: Chris DorsettLearn more about Chris Dorsett and Ocean Conservency hereRead Motion 035Follow the IUCN World Conference and find the full list of motions here Follow Ocean Conservancy on Instagram , Blue Sky, LinkedInEpisode Transcript  and more information on the Pine Forest Media websiteFollow Pine Forest Media on Instagram @pineforestmediaHosted, produced, and edited by Clark Marchese Cover art by Jomiro EmingTheme music by Nela RuizFind some more Pine Forest Media podcasts below:Listen to South Pole 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.
