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 <a href="https://patreon.com/PineForestMedia?utm_medium=unknown&utm_source=join_link&utm_campaign=creatorshare_creator&utm_content=copyLink" rel="noopener noreferrer" target="_blank">Patreon</a> or sending us a gift on <a href="https://www.paypal.biz/pineforestmedia" rel="noopener noreferrer" target="_blank">PayPal</a>Episode Guest: Chris DorsettLearn more about <a href="https://oceanconservancy.org/people/chris-dorsett/" rel="noopener noreferrer" target="_blank">Chris Dorsett </a>and <a href="https://oceanconservancy.org/" rel="noopener noreferrer" target="_blank">Ocean Conservency</a> hereRead <a href="https://iucncongress2025.org/assembly/motions/motion/035" rel="noopener noreferrer" target="_blank">Motion 035</a>Follow the<a href="https://iucncongress2025.org/" rel="noopener noreferrer" target="_blank"> IUCN World Conference </a>and find the<a href="https://iucncongress2025.org/assembly/motions/list" rel="noopener noreferrer" target="_blank"> full list of motions </a>here&nbsp;Follow Ocean Conservancy on <a href="https://www.instagram.com/oceanconservancy/" rel="noopener noreferrer" target="_blank">Instagram</a> , <a href="https://bsky.app/profile/oceanconservancy.org" rel="noopener noreferrer" target="_blank">Blue Sky,</a> <a href="https://www.linkedin.com/company/ocean-conservancy/" rel="noopener noreferrer" target="_blank">LinkedIn</a>Episode Transcript&nbsp; and more information on the <a href="http://pineforestpods.com" rel="noopener noreferrer" target="_blank">Pine Forest Media </a>websiteFollow Pine Forest Media on Instagram <a href="https://www.instagram.com/pineforestmedia/" rel="noopener noreferrer" target="_blank">@pineforestmedia</a>Hosted, produced, and edited by Clark Marchese&nbsp;Cover art by<a href="https://jomiro.webflow.io/about" rel="noopener noreferrer" target="_blank"> Jomiro Eming</a>Theme music by <a href="http://nelaruizcomposer.com" rel="noopener noreferrer" target="_blank">Nela Ruiz</a>Find some more Pine Forest Media podcasts below:Listen to South Pole on <a href="https://open.spotify.com/show/292f9HcD3eCI2V6hLQG2Hi?si=j0TSZkmgQNWy4WCPfNHMXQ" rel="noopener noreferrer" target="_blank">Spotify</a> or <a href="https://podcasts.apple.com/us/podcast/south-pole/id1748730442" rel="noopener noreferrer" target="_blank">Apple Podcasts</a>Listen to Plastic Podcast on <a href="https://open.spotify.com/show/4Iv20PynWeNKEZtq5O5UOj?si=MW-ZYI8zS0mUroec9T_lfA" rel="noopener noreferrer" target="_blank">Spotify</a> or <a href="https://podcasts.apple.com/us/podcast/plastic-podcast/id1737963995" rel="noopener noreferrer" target="_blank">Apple Podcasts</a>Listen to Something in the Water on <a href="https://open.spotify.com/show/5HGQytPxV6FfcX03OUBXYf?si=YszhS8C4ToafplCEsEErAQ" rel="noopener noreferrer" target="_blank">Spotify</a> or <a href="https://podcasts.apple.com/us/podcast/something-in-the-water/id1740586381" rel="noopener noreferrer" target="_blank">Apple Podcasts</a><hr> Hosted on Acast.
