  • Understanding the Mysterious Loop Current
    Dec 18 2025

    The amazing science behind understanding mysterious but critical ocean currents. And specifically, understanding the current in our backyard, the Gulf’s Loop Current.

    We talk with scientists leading a huge multi-country research collaboration that is going to great lengths and depths to understand the especially unknown Loop Current. We talk about how currents connect us, how they are basically a thermostat for the globe, and why, more than ever before, we need to understand them.

  • Farming the Ocean: Part 2
    Dec 3 2025

    This is part 2 of a 2-part series exploring the future of farming seafood in the Gulf. We know this: demand for seafood is soaring. We won't be able to sustainably meet that demand from wild-caught fisheries. And there’s a growing global movement to farm more and more of our seafood.

    The Gulf is one of the LAST places in the world where there is still a major wild oyster harvest. Lately, though, that harvest…is in trouble. In this episode, we ask: What can the downfall and resurrection of the oyster tell us about a future of farming the ocean?

  • Farming the Ocean: Part 1
    Nov 21 2025

    This is part 1 of a 2-part series exploring the future of farming seafood in the Gulf. Americans eat a lot of farmed seafood — but the vast majority of it comes from overseas. We just don’t farm fish on a big scale in U.S. waters. Now that might start to change. There are proposals to build massive fish farms in U.S. federal waters. And guess which coast is likely to be the first home for these new farms? You guessed it, the Gulf.

    So is this a miracle cure or a looming ecological disaster?

  • Classic Episode: Riddle of the Kemp's Ridley Sea Turtle
    Nov 13 2025

    The story we are bringing you today is about sea turtles. In fact, it’s about the smallest and most endangered of sea turtles, called the Kemp’s Ridley. It’s a surprising and optimistic tale about a turtle’s return to Louisiana.

    We reported this episode back in 2023, but we wanted to revisit it because who doesn’t need more sea turtles in their life right now? And also because there has been some big news for sea turtles recently.

    This episode was hosted and produced by Carlyle Calhoun. Sea Change's theme music is by Jon Batiste, and our sound designer is Emily Jankowski. Carlyle Calhoun is the executive producer.

  • No Matter the Water
    Oct 25 2025

    What does it take to stay rooted on the Gulf Coast, even as the land and weather change around us? We meet individuals, from a poet to a minister to a computer programmer, each finding their own creative ways to adapt and fight for the future of their communities. From amphibious homes to inland retreats to processing our changing environment through poetry, we hear how people's ingenuity is helping chart a new path forward.

  • The Quiet Revolution Saving Fish and Fishermen
    Oct 9 2025

    There was a time back in the 1980s when overfishing had decimated popular fish like red snapper and grouper in the Gulf. But then, there was a dramatic turning point, when both fish and fishermen in the Gulf were kind of saved. Today, we hear the remarkable success story of how unlikely partners joined forces to save an industry and an ecosystem.

    In this episode, Environmental Defense Fund's Executive Director, Amanda Leland, water resilience author, James Workman, and fisherman, Buddy Guidon, talk about how catch shares created a quiet revolution.

    To learn more, check out Amanda and James' book, Sea Change: Unlikely Allies and a Success Story of Oceanic Proportions.

  • The Trojan Seahorse
    Sep 24 2025

    Today, we’re bringing you a wild story. It’s about a covert ocean adventure from back in the Cold War days that inadvertently set off a brand new industry. And it’s an industry that’s been in the news a lot lately: deep-sea mining.

    Earlier this year, President Trump signed an executive order to try to fast-track deep-sea mining, while many countries are calling for more research before any mining can proceed or an outright ban. The deep ocean is the least known place on Earth, and scientists say we are only beginning to understand the power of the deep.

    And to tell the incredible backstory of how the industry that could forever change our ocean got its start, we are bringing you an episode from one of our favorite public radio podcasts: Outside/In from New Hampshire Public Radio.

    This episode was reported and produced by Daniel Ackerman.

    Today, we bring you three stories exploring what it really takes to be ready for the next big storm. But at their core, these stories are about something deeper: the determination to keep living here on the Gulf Coast, and about the choices we’re making that will decide whether that’s possible.
