    Dr. Sylvia Earle: Transforming Seeing Into Knowing Into Action | S5E1

    In this special episode of REEF Roundup, we share the unforgettable conversation we had with the legendary Dr. Sylvia Earle. Recorded on location at the IUCN World Conservation Congress in Abu Dhabi, this interview captures an intimate moment with one of the world's most iconic oceanographers. Dr. Earle shares her perspective on the transformative power of scuba diving, describing it as a pivotal step that just recently began allowing terrestrial beings to explore the majority of our biosphere. We discuss the critical shift from viewing marine life as a commodity ("I want to eat you") to viewing them as individuals ("I want to know you"), and why divers, who witness the underwater world firsthand, have a unique privilege and responsibility to speak up for the ocean.

    Linzi Hawkin of Protect Blue: Designing a Regenerative Ocean Culture | S4E5

    In this episode of REEF Roundup, we sit down with Linzi Hawkin, co-founder of Protect Blue, and explore the special combination of thoughtful strategy and human joy that is essential to being impactful in your efforts to care for the ocean. Linzi shares her journey from running surf schools in Jersey to designing impact strategies for global NGOs. We dive deep into the dangers of "shiny" storytelling, the importance of nervous system regulation for ocean advocates, and why "water breaks" should be the first thing you seek out at the next ocean conference you attend. Key Takeaways Strategy & Stoke: Why ocean conservation needs both measurable impact data and the joy of connecting with the ocean to be sustainable. Beating Burnout: Practical advice on managing overwork and climate anxiety, including "sit spots" and setting boundaries (like Linziā€™s "No-Call Fridays"). Impact VS Storytelling: Why we need funding and support for "scrappier," more authentic projects that support and celebrate those in the trenches doing the work. The "Robin Hood" Model: How Protect Blue takes high-level agency tools and makes them accessible to grassroots frontline communities. Featured Quotes "If you don't have time to meditate for five minutes, you need to meditate for five hours." ā€” Linzi Hawkin "We're almost creating this really false narrative... like we're all just swimming with manta rays every day... I want to champion and celebrate some of that behind the scenes work." ā€” Linzi Hawkin "Do not burn yourselves out. Be as I am - a reluctant enthusiast... a part-time crusader... Save the other half of yourselves and your lives for pleasure and adventure." ā€” Edward Abbey (read by Linzi) Mentioned in this Episode Damon Gameau (Filmmaker, 2040): @damongameau SeaTrees (Ocean regeneration project): @sea.trees

    Virgil Zetterlind of Protected Seas: Mapping Ocean Protections and Closing the Enforcement Gap | S4E4

    In this episode, we sit down with Virgil Zetterlind, Director of Protected Seas, to discuss the critical difference between declaring a Marine Protected Area (MPA) and it actually leading to the intended positive outcomes we hope to achieve. It's a more complex topic than we often cover, but incredibly important. So grab a cup of coffee, perhaps a notepad, and a comfortable seat before you dive in. While global targets like 30x30 and the High Seas Treaty dominate the headlines, the reality on the ocean is that much of it is often a Wild West of overlapping regulations and limited visibility. Virgil walks us through how Protected Seas is solving this knowlege and data gap by mapping the global regulatory landscape with their Navigator tool and deploying autonomous radar systems (M2) to monitor compliance in real-time. In this episode, youā€™ll hear about: Visualizing the Invisible ā€“ How the Navigator tool standardizes complex, layered legal texts into a "Level of Fishing Protection" score, allowing users to see exactly what activities are allowed in any patch of ocean. Closing the Enforcement Gap ā€“ The transition from "paper parks", areas that are protected by law, but not in reality, to protected waters using M2 (Marine Monitor), a non-cooperative radar technology that tracks near-shore vessel movement without relying on AIS signals. The Economics of Protection ā€“ Data from Mexico and beyond proving that scuba divers are willing to pay a premium to visit fully protected areas, making a clear economic case for strict no-take zones. Data Over Intuition ā€“ A case study from California where radar data disproved the assumption that poaching happens at night, revealing that most illegal fishing occurred in broad daylight which shifted enforcement strategies. High Seas & 30x30 ā€“ The logistical challenges of implementing the new High Seas Treaty and the difficulty of tracking "Other Effective Conservation Measures" (OECMs) without standardized metrics. Protected SeasProtected Seas is a team of data scientists, mariners, and conservationists dedicated to bridging the gap between ocean policy and reality. Their open-access tools, including the Navigator map and M2 radar systems, empower governments, NGOs, and ocean users to understand regulations and improve compliance.

    TrƩ Packard of PangeaSeed: Using Art to Make Marine Conservation Visible | S4E3

    In this episode, we sit down with TrĆ© Packard, founder and Executive Director of PangeaSeed Foundation, to explore how public art can turn abstract ocean science into something people can see, feel, and act on. From shark fin markets in Asia to large-scale mural festivals and fine art print releases, TrĆ© walks through how PangeaSeed built a global model that funds conservation work, supports artists, and brings the ocean into city streets. In this episode, youā€™ll hear about: Art as a gateway to empathy ā€“ why emotional connection is as important as scientific literacy for driving change, especially for people who will never put on a mask or scuba tank. The origin of Sea Walls ā€“ how the uncovering of the largest shark finning operation in the world and a mural in a Sri Lanka sparked the idea of using large-scale public art as a democratic, free platform for ocean stories. Printed Oceans and the ā€œbusiness of conservationā€ ā€“ how limited-edition fine art prints create a circular economy that funds programs, supports artists, and brings conservation narratives into homes, schools, and workplaces. Cross-sector collaborations ā€“ examples of working with dive agencies, city governments, brands, and international institutions to align communications, funding, and science around local ocean threats. Longevity and resilience in ocean advocacy ā€“ lessons from 15+ years in the field, including burnout, hope, and how to keep going when the problems are heavy and long-term. PangeaSeed Foundation is a nonprofit working at the intersection of art, science, and education to advance ocean conservation. Through programs like Sea Walls: Artists for Oceans, Printed Oceans, and their Impact and Commissioned Programs, PangeaSeed connects scientists and communities with a global network of artists to turn complex marine issues into accessible visual stories. Their work addresses priority ocean challenges such as overfishing, plastic pollution, and climate impacts worldwide.

    Rose Huizenga: Creating a New Generation of Coral Superwomen | S4E1

    In this episode, weā€™re honored to feature Rose Huizenga, founder of Coral Catch and co-founder of Gili Shark Conservation. Originally from the Netherlands, Rose has spent the past decade on Gili Air, Indonesia, transforming a dream to restore her islandā€™s reefs into a powerful movement for ocean conservation and womenā€™s empowerment. Through Coral Catch, Rose has built a sisterhood of local womenā€”known as the Coral Catch Superwomenā€”who are trained as certified divers, reef restoration experts, and community leaders. These women are not only reviving reefs across Indonesia but also sparking ripple effects of change in their communities, proving that empowering women is a catalyst for stronger ecosystems and societies. For Rose, this mission is deeply personal. Every time she takes her daughters into the ocean, sheā€™s reminded why she began: so the next generation can inherit a living, thriving ocean. Her vision is bold yet tangibleā€”to empower 100 women to pursue conservation careers and 100 more to learn how to swim, ensuring a brighter future for both people and reefs. If youā€™re looking for a powerful story of how one personā€™s dream can ignite lasting change, this episode is a must-listen. Follow the journeys of the Coral Catch Superwomen on Instagram @coralcatch, and support their work at coralcatch.org/donate.
