  • It's All Elementary: Part 1 – Nitrogen
    Jun 5 2026

    In this three-part series, we’re giving some of the most misunderstood characters on the periodic table a fuller story. We dive into the fascinating double lives of these elements that are both the makers and unmakers of our world.

    In part one, reporter Olga Loginova travels to Cape Cod to meet nitrogen. In this episode: we trudge through the marsh, avoid great white sharks, and find out how we harnessed the power of nitrogen, why that power turned against us, and what we can do about it.

  • Losing Paradise
    May 6 2026

    Why are fishermen being arrested in Louisiana? An epic battle over "Sportsman's Paradise" is being waged on Louisiana's water. This is a story about public rights and private power colliding. As more and more of Louisiana’s coast disappears underwater, the state’s two most powerful and iconic forces – fishing and fossil fuels – are waging war over who owns the drowned land.

    Check out a print version of this story in Southlands Magazine. Read and subscribe here.

    Want to dive even deeper into the legal issues surrounding this story? Beginning with how private ownership of wetlands traces back to the Swamp Land Grant Acts in the 1800s? Then check out property law scholar John Lovett's legal paper.

  • Catching the Codfather
    Apr 23 2026

    Carlos Rafael immigrated to the US from Portugal as a teenager, and over the years, built one of the country’s largest commercial fishing operations from scratch. Carlos owned the biggest fleet of boats in the most valuable fishing port in America. He became known as the Codfather. But it all came crashing down in a federal sting.

    Who is Carlos Rafael? Depending on who you ask, he's either a villain who robbed the ocean or a kind of folk hero who stood up for fishermen.

    Today, we’re bringing you the first episode of Catching the Codfather from our friends at GBH News.

    It’s often said that the U.S. has the most sustainable fisheries in the world. Laws have been designed to prevent overfishing, rebuild stocks, and protect a shared public resource. But, for the people living inside that system, it can feel very different. And that tension isn’t unique to New England.

    Along the Gulf Coast, we often hear from shrimpers, oystermen, and anglers who say they’re being regulated out of a way of life. At the same time, we know what’s at stake if those rules fail. So where is the line? Catching the Codfather doesn’t offer easy answers. Instead, it tells a story about power, policy, and the complicated reality of managing a shared resource.

    Listen to the rest of the series, Catching the Codfather, wherever you get your podcasts. The series is part of an ongoing documentary feed from GBH News called The Big Dig.

    This episode of Sea Change Live was hosted by executive producer Carlyle Calhoun. Our theme music is by Jon Batiste. This episode was reported by Ian Coss.

  • Returning to the Carbon Coast
    Apr 9 2026

    Two years ago, we investigated the Liquified Natural Gas export build out on the Gulf Coast. We followed those exports around the world from Louisiana to Germany to Japan to unravel the story of LNG.

    But that story isn’t over. Today, host Carlyle Calhoun returns to LNG with Gulf States Newsroom reporter Drew Hawkins. They talk about how people in Southwest Louisiana are still being impacted by this build out, how LNG exports are affecting your electricity bills and what the war in Iran means for this industry.

    “Carbon Coast” is part one of our three part series about LNG called “All Gassed Up,” reported and produced by Halle Parker and Carlyle Calhoun. You can listen to parts two and three by searching for “All Gassed Up” in our feed.

  • Can We Save Millions of Migrating Birds?
    Mar 25 2026

    We’re in the beginning of spring bird migration here on the Gulf Coast, which means warblers, vireos, orioles, and thrushes coming through as they make their way up North. Around 2 billion birds make landfall along our coast from March to May after crossing the Gulf of Mexico. But even after the high-stakes crossing of open water, their next leg of the journey is no less perilous.

    In this episode, our friends from Up From Dust tell us a story about a phenomenon threatening birds on their long flights, and we learn how we can all do our part to help them on their journeys.

  • Sea Change Live: The Future of Seafood
    Mar 11 2026

    Sea Change travels to the Walter Anderson Museum of Art in Ocean Springs, Mississippi, for a lively live panel discussion about the future of seafood.

    For more than a century, the Gulf seafood industry has shaped towns, cultures, and identities along the coast. Yet, if you talk to almost anyone who works on the water, they’ll tell you the Gulf seafood story has changed more in the last 30 years than the hundred years before that. If you care about what’s on your plate, what happens to this coast, or what kind of future we’re leaving to the next generation of fishers and eaters, you’re in the right place.

    Feb 25 2026

    Artificial reefs have been credited with supporting fisheries, protecting rare species, and attracting tourists that boost the economy. But, of course, like any story about the environment, it gets complicated both here in the Gulf and on Cambodia’s coast.
