Tracing the interconnected threads of land, water, loss, and resilience in the Gulf South

In this first installment of our special Southern Currents series, Bill travels the Gulf Coast (sadly, without Anders) to explore the crisis of coastal land loss and the role of citizen science in protecting the region’s future.

We begin in Louisiana with Pulitzer Prize–winning journalist Bob Marshall, who has spent decades covering the collapse of his home state’s coastal wetlands. Speaking from Bayou Segnette State Park just outside New Orleans, Bob explains why the term “vanishing wetlands” is misleading; these ecosystems aren’t quietly disappearing, they’re violently collapsing. He walks us through the cumulative impact of levees, oil and gas canals, and a century of development that has blocked sediment flows, eroded plant life, and left whole regions to sink. With urgency and clarity, Bob unpacks the consequences for fisheries, waterfowl, communities, and the entire Gulf ecosystem, while reflecting on his journey from sportswriter to environmental advocate. He also shares insights into Louisiana’s $50 billion Coastal Master Plan and why, even with action, parts of the “boot” may be impossible to save.

Then we shift east to the Florida panhandle, where marine biologist, author, and lifelong mischief-maker Jack Rudloe tells the story of founding the Gulf Specimen Marine Lab in Panacea, Florida. Jack recounts his early days collecting marine life for research institutions, the skepticism he faced from locals, and how he learned marine biology the hard way—by doing it. He reflects on his mentorship with John Steinbeck, his clashes with the academic establishment, and the evolution of the lab from a “leaky shack” into a hub of public education and conservation. Along the way, Jack makes a passionate case for tactile science—learning through touch and immersion—and introduces his unlikely campaign to restore oyster populations by placing logs in the bay. He also doesn’t hold back about the political and social obstacles he’s faced, or the price of being a proud environmentalist in a region often suspicious of that word.

Together, these conversations trace the interconnected threads of land, water, loss, and resilience in the Gulf South and ask what it means to fight for wild places when those places are rapidly disappearing.

Today, we explore:

Part 1: Louisiana’s Collapsing Coastline

• Why Louisiana’s wetlands aren’t “vanishing”; they’re collapsing
• The engineering and industry decisions that accelerated land loss
• The historic role of oil and gas companies in shaping the coast
• Bob’s transition from NFL reporter to environmental journalist
• How marsh loss impacts fisheries, storms, and wildlife
• Louisiana’s $50 billion Coastal Master Plan and what it can (and can’t) save
• The future of New Orleans and the Gulf Coast under sea level rise
  

Part 2: Science, Education, and Resilience in Florida

• Jack’s journey from dropout to founder of Gulf Specimen Marine Lab
• Citizen science, hands-on learning, and the fight to keep marine biology accessible
• His time on a research expedition to Madagascar and early ties to Harvard
• Building trust with local fishing communities and confronting local resistance
• Oyster restoration using logs, and the bureaucratic resistance to natural solutions
• Why Rudloe believes kids must see and touch marine life to become stewards of it
• The enduring legacy of his work with schoolchildren, researchers, and activists

Bob Marshall is a Pulitzer Prize–winning journalist and lifelong outdoorsman who has spent his career reporting on the complex relationship between people, policy, and the vanishing wetlands of southern Louisiana. A former reporter and columnist for The Times-Picayune and The Lens, Bob is known for combining rigorous environmental reporting with a deep personal connection to the landscapes he writes about. He has covered everything from hurricanes and levee failures to fisheries management, land loss, and climate policy, often sounding the alarm on Louisiana’s ecological crisis long before it reached national headlines.

A native of Uptown New Orleans, Bob has spent decades fishing, hunting, and paddling Louisiana’s marshes, and continues to use storytelling as a tool for education, advocacy, and action.

Jack Rudloe is a marine biologist, author, and environmental advocate whose life’s work has been dedicated to exploring, understanding, and protecting the rich biodiversity of the Gulf Coast. Based in Panacea, Florida, Jack is the founder of the Gulf Specimen Marine Laboratory, a hands-on marine life education center and biological supply lab that has introduced generations of students, scientists, and curious visitors to the hidden wonders of coastal ecosystems.

For over six decades, Jack has worked at the intersection of science and storytelling, collecting marine specimens, fighting for habitat protection, and writing vividly about the natural world. His books, including The Sea Brings Forth, The Living Dock, and Time of the Turtle, blend scientific insight with personal experience, often drawing on his early collaborations with institutions like Harvard and his correspondence with John Steinbeck. Jack’s work has contributed to cancer research, space biology, and marine conservation, while his unflinching environmental activism has made him both a local fixture and, at times, a controversial figure.

Through fieldwork, education, and a lifelong commitment to the Gulf’s fragile ecosystems, Jack Rudloe continues to be a fierce and unapologetic advocate for the life found in the margins of land and sea.
