On the latest episode of Rising Tide, hosts David Helvarg and Vicki Nichols Goldstein sit down with Erin Hudson, Director of the Seafood Watch program at the world-renowned Monterey Bay Aquarium.

With more than 15 years dedicated to advancing sustainable seafood, Hudson brings deep insight into how consumer choices ripple through ocean ecosystems and fishing communities. The conversation traces the origins of Seafood Watch’s iconic red, yellow, and green pocket guides—a simple, powerful tool that helps people understand which seafood choices are environmentally responsible, risky, or best avoided. To date, more than 65 million of these guides have been distributed worldwide.

The episode also explores Hudson’s collaborative work with the fishing industry and retailers, and why meaningful change can sometimes start with asking one clear, straightforward question.

It’s a smart, accessible, and surprisingly delicious listen—proof that informed choices can be good for both people and the planet.

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.

In the latest episode of Rising Tide: The Ocean Podcast, David Helvarg and Vicki Nichols Goldstein speak with longtime ocean activist and former guest Richard Charter about the Trump administration’s punitive effort to open the entire California coastline to offshore oil drilling. It has been several years since their last conversation with Charter, who has spent decades leading efforts to protect America’s coastal seas.

The discussion centers on the Department of the Interior’s latest offshore lease plan, which would open Arctic waters, the eastern Gulf of Mexico, and California’s 1,100-mile coastline to drilling—despite polls showing that more than 70% of Californians oppose the move.



Charter outlines the laws this plan would violate, the growing opposition mobilizing to stop it, and the hypocrisy he sees in the administration’s declared “Energy Emergency.” He also explains why this moment may represent the “last gasp” of Big Oil, and what people in California and across the country are doing—and can do—to challenge this dangerous and likely illegal proposal.

In this year-end episode Holden Hardcastle and Nick Paz do an on-the-ground (actually on the beach) interview with Vince Yuen, founder of 'Refuse, Refuse San Francisco.' During a beach clean-up on the city's oceanfront he discusses the significance of community-led trash cleanups in protecting the environment. Vince shares how his organization started as a personal project during the COVID pandemic and evolved into a city-wide movement aimed at reducing urban litter and its impact on all waterways. The discussion also touches on legislative efforts to reduce cigarette butts and single-use plastics, illustrating how collective citizen action and policy changes are crucial for lasting environmental impact.

In the latest episode of Rising Tide, David Helvarg speaks with Peter Gros and Dr. Rae Wynn-Grant, co-hosts of “Mutual of Omaha’s Wild Kingdom: Protecting the Wild,” a show whose origins go back to 1963, when most televisions were still black and white, but wildlife was both more abundant and less understood. 

Today, you can see their Emmy-nominated television show on Saturday mornings on NBC or watch it on Peacock, Amazon Prime, YouTube - so many outlets, you have no excuse not to watch it, once you’ve heard what they have to say on this podcast.    

Peter Gros is, among other things, a wildlife expert, a licensed animal educator, and a 40-year veteran of the show many of us grew up on.

Dr. Wynn-Grant is a wildlife ecologist specializing in carnivore-human interactions who also focuses on expanding science communications and sustainability. A National Geographic research fellow and author, she joined the show in 2023. 

‘Wild Kingdom’ is also getting saltier over time with more ocean shows on gray whales, white sharks, coral reefs, and one of our favorites, kelp forests, including their most famous residents, the voracious marine weasels also known as sea otters. So, dive in for a fun and informative interview with these two land and sea stars.

In the latest episode, David Helvarg and Natasha Benjamin speak with Amy Bowers Cordalis of California’s Yurok Tribe about her life and her new book, The Water Remembers: My Indigenous Family’s Fight to Save a River and a Way of Life. Amy, the former general counsel for the Yurok Tribe, the largest tribe in California, living along the Klamath River, shares the story of her family’s leadership in the historic effort to remove four dams on the Klamath following the devastating 2002 fish kill. She reflects on how the Yurok and neighboring Klamath Basin tribes mobilized, organized, and persevered to restore the river’s health and its wild salmon.

A co-founder of the Ridges to Riffles Conservation Group, Amy has been recognized globally as a UN Champion of the Earth Laureate and one of TIME’s 100 Most Influential Climate Leaders. This episode explores what it means to be born of wild water, to uphold a culture of world renewal, and to take real-world action to protect and restore a river, its people, and our blue planet.

In the latest episode, David Helvarg & Vicki Nichols Goldstein talk with the Reverend Robert Wilkins about how his faith led him to his work with the Seafarers Ministry, serving ship crews arriving at the Port of Oakland, California. Wilkins and his team make ship visits, help crew members connect with families in places like the Philippines and Bangladesh, and check in on conditions such as time spent at sea and food quality — often doing follow-up when issues arise.

They also support mariners on shore leave with recreation, transportation, and other needs, and even coordinate doctor visits when necessary, frequently working with Customs and Border Protection to make it happen. 

Each holiday season, the ministry delivers gift bags to seafarers and continues to grow its volunteer program, expanding ship visits from 250 vessels to 370 this year — supporting the people responsible for moving more than 90% of the world’s goods.

Wilkins also shares his perspective on shipping automation and decarbonization, exploring how these changes are already affecting seafarers and may reshape their livelihoods in the future.

Tune in to this insightful conversation with Rev. Wilkins and gain his unique perspective.

In the latest episode of ‘Rising Tide, the Ocean Podcast,’ David and Natasha speak with Dr. Ben Halpern. Along with being a past Peter Benchley Ocean Award winner, Ben serves as Director of the National Center for Ecological Analysis and Synthesis, a research center at the University of California, Santa Barbara, where he is also a professor of marine biology and conservation science. Among his numerous honors and research papers, he’s contributed to a new report published in Science magazine warning that the world’s ecosystems could be permanently altered – meaning degraded - by mid-century if the present trend in greenhouse gas pollution, industrial overfishing, and coastal development continues unabated. Ben also offers some ideas on how each of us can act in ways that can help reverse that trend. So, give a listen, learn a bit, and visit the ocean when you can.
