Exploring the Depths: An Investigative Dive on Ocean Conservation and Cultural Impact

In the latest episode of Rising Tide the Ocean Podcast David Helvarg and Vicki Nichols Goldstein have an engaging conversation with Paul Greenberg, author of the best-selling book ‘Four Fish’ and more recent writings including his latest novel ‘A Third Term’ (George Washington takes on Donald Trump). A Writer in Residence at the Safina Center, a former Pew Fellow and recipient of many honors, Paul discusses growing up fishing, his literary journey (with a short jaunt into Semiotics) how people’s habits and perceptions often differ from common environmental messaging they receive and why Bluefin Tuna give him hope for the future. Tune in for a thoughtful and thought- provoking conversation in depth with our guest Paul Greenberg.

Unraveling the Threads of Change: From Photography to Global Environmental Advocacy

Academy Award-winning director Louie Psihoyos returned to the Rising Tide Ocean Podcast for a conversation as wide-ranging and urgent as his films. Host David Helvarg sat down with Psihoyos before a live audience during SF Climate Week at the downtown San Francisco studios of KALW public radio — and the exchange didn't disappoint.

Psihoyos traces his unlikely path to ocean advocacy: a kid from Iowa, drawn early to photography and the sea, who eventually landed at National Geographic — beginning, as origin stories often do, at the bottom, sifting through a garbage dig. From there he rose to become one of the most consequential documentary filmmakers working today, a man who doesn't just point a camera at environmental catastrophe but builds covert operations around it.

He recounts the making of The Cove, his shattering exposé of the dolphin slaughter in Taiji, Japan — a film that required as much tradecraft as filmmaking — and discusses his latest work, Plastic Detox, now streaming on Netflix, which takes a hard look at microplastics and their alarming effects on human fertility.

The two also range across a broader landscape: adventures, causes for concern, and — perhaps most valuably in these grinding times — reasons for optimism.

It's a talk worth diving into.

Exploring the Forgotten Frontlines of Our Ocean's Battle Against Climate Change

The tables turn on the latest episode of Rising Tide the Ocean Podcast as Blue Frontier’s Natasha Benjamin interviews Rising Tide co-host and author David Helvarg on his latest book, ‘Forest of the Sea – The Remarkable Life and Imperiled Future of Kelp’ (coming out May 5th). As co-director of the award-winning kelp forest documentary ‘Sequoias of the Sea’ Natasha is also steeped in the mystery, wonder and peril of these great underwater forests of life and light. So, their discussion ranges over both familiar territory – how a changing warming ocean is impacting kelp forests that have been around over 30 million years - to some of the newer things David discovered during his two years researching the book, interviewing and diving with a wide range of people and creatures from Alaska to California, Maine, Turkey, Palau – for his chapter ‘Kelp is the new Coral’ - and other far-flung waterfronts where the world’s kelp forests, cover an area larger than the Amazon rainforest. He talks about how they’ve gotten into serious trouble even as they provide us half a trillion dollars of services a year including as ‘the mother seed’ for global food security in fishing and seaweed aquaculture.

It’s a fun romp through an entangling wonderland, which is why Rising Tide recommends you give a listen and then buy David’s book (preferably through your local independent bookstore).

Explore the alliance between fishermen and environmentalists that is reshaping the industry and safeguarding marine life.

On the latest episode of Rising Tide the Ocean Podcast, host David Helvarg and co-host Vicki Nichols Goldstein sit down with James Workman and Amanda Leland, co-authors of Sea Change – Unlikely Allies and a Success Story of Oceanic Proportions — a book that makes a convincing case that empowering fishermen to work together, even as they compete, can create miracles.

Workman brings the instincts of an award-winning journalist and entrepreneur to the conversation, having already explored humanity's most elemental struggles in his earlier work, Heart of Dryness. Leland came to the sea the way many do — through a grandfather and a fishing line at age five — and never left. Today she serves as Executive Director of the Environmental Defense Fund, the international nonprofit working to align healthy communities and economies with the hard realities of a changing climate.

Together, they dig into the market-based system known as catch share fishing: what it is, how it's reshaping the destructive race toward overfishing in U.S. waters, and why it may be one of the most promising tools we have for getting this right on a global scale. They also explore the human cost baked into commercial fishing — still one of the deadliest jobs on earth — and how catch shares are changing those odds. And they explain their choice to tell this sweeping story through the life of one rugged Gulf Coast fisherman named Buddy, a narrative anchor that grounds the policy and the science in salt, sweat and consequence.

All of it plays out against the backdrop of a rapidly warming, rapidly changing ocean — and what that means for the millions of people whose dinner plates depend on getting this right.

A story of hope, hard-won transformation and new challenges. Dive in and take an audio bite.

On the latest episode of Rising Tide, hosts David Helvarg and Vicki Nichols-Goldstein sit down with Angelo Villagomez, Senior Ocean Fellow at the Center for American Progress in Washington D.C. — a man who has spent his career turning conviction into policy at the edges of the map.

A longtime activist and advocate for community and indigenous governance, Villagomez was a central force behind the establishment of the Mariana Trench National Marine Monument, doing the hard, unglamorous work of coalition-building from the ground up while based in Saipan, deep in the western Pacific.

The conversation turns, as it must, to the present dangers. The Trump administration has set its sights on the nation's marine monuments, thrown open the door to deep-sea mining with reckless enthusiasm, and pursued what can only be described as a vendetta against offshore wind — apparently terrified of a wind-spill — while greasing every available skid for oil and gas expansion. Meanwhile, the institutional backbone of American ocean science, the National Oceanic and Atmospheric Administration, is being quietly hollowed out from within.

But Villagomez and his hosts don't stop at the diagnosis. The episode maps a course forward — from protecting local waters to hitting the streets (signs reading "No Kings but king salmon" are apparently optional but encouraged), registering to vote, and casting ballots with the ocean in mind come November.

If information is a weapon for positive change, this conversation is live ammunition.

Breaking Barriers & Pioneering Pursuits

On the latest episode of Rising Tide, bodysurfer David Helvarg and board surfer Natasha Benjamin sit down with photographer, filmmaker, and journalist Sachi Cunningham — a woman who has spent more than two decades pointing her lens at the pioneers rewriting what's possible in big wave surfing.

Cunningham helped build the LA Times video team from the ground up, producing the award-winning Chasing the Swell series and documenting the historic first women's heats at Mavericks, the legendary big wave break that rises from the deep-water canyon just south of San Francisco. Now living within earshot of Ocean Beach, she's putting the finishing touches on her first major documentary, Big Wave Women — a film tracking the hard-won fight for pay equity among the elite athletes drawn, or perhaps driven, to ride some of the most dangerous walls of water on the planet.

The conversation ranges wide: the cameras she trusts in the impact zone, the technical and physical demands of shooting from inside the surf, and a recent piece she wrote examining the geology and marine ecosystems that make Mavericks not just a spectacle, but a living seascape. It's a session that goes well below the surface.

On the latest episode of *Rising Tide*, hosts David Helvarg and Vicki Nichols Goldstein sit down with Mark Benjamin and Katie Carpenter, co-directors of the powerful feature documentary Fatal Watch.

Fatal Watch exposes the darkest underbelly of the global fishing industry—the murder and suspicious deaths of dozens of onboard fisheries observers assigned by the tuna industry and others to document illegal activities aboard commercial fishing vessels. Through an examination of multiple cases, including video evidence of observers supposedly “lost at sea,” the film reveals the profound difficulty of holding anyone accountable.

Spanning the world’s waterfronts and open seas, Benjamin and Carpenter follow criminal investigators, industry critics, and the families left behind—people fighting through grief in pursuit of truth and justice.

Fatal Watch is now available for streaming on Apple TV, YouTube, and other platforms. After listening to this wide-ranging and revealing conversation, audiences will undoubtedly want to experience the film for themselves.

In the latest episode of Rising Tide: The Ocean Podcast, David Helvarg and Vicki Nichols Goldstein speak with former guests and good friends of the Ocean Philippe and Ashlan Cousteau. Philippe is the third generation of the legendary family of Jacques Cousteau and a founder of the youth group Earth Echo International. Ashlan is a former entertainment journalist who now reports on the doings of sea stars and influencers of climate. Together they’ve produced ocean documentaries for CNN, the Discovery Channel and others, written books including ‘Oceans for Dummies’ and now are engaged in an effort to protect Antarctica’s Southern Ocean. They are supporting the establishment of protected areas and opposing massive commercial krill fishing that threatens the sea life, including penguins and whales, that depend on these tiny crustaceans. They have also launched an Omega 3 algae-based supplement – SeaVoir - to provide a healthier alternative to krill (or fish) oil that they also discuss. So, a fascinating encounter with a dynamic ocean duo. Please do listen in.
