Speak Up for Blue Podcast Network

In September 2021, Time magazine profiled Gerard Barron, CEO of The Metals Company (TMC), and his push to mine the Clarion Clipperton Zone (CCZ), a stretch of international seabed between Hawaii and Mexico. In that profile, Barron called the CCZ "the most desert-like place on the planet," arguing that mining the deep sea does less environmental harm than mining a rainforest because there's supposedly so little life down there to disturb. That single line has been repeated for years as justificat

Why would someone who watched one deep-sea mining company collapse go back and try it again? That's the question at the center of this episode, and it's not hypothetical. It happened, with the same industry, some of the same licenses, and the same person at the center of it: Gerard Barron, now CEO of The Metals Company (TMC), one of the most prominent and best-funded companies pushing to start commercial deep-sea mining today. This isn't framed as an accusation against Barron specifically. It's

Dr. Chris Dudgeon has spent more than two decades studying some of the ocean's strangest and least understood sharks, from the reef-walking Hemiscyllium species of Papua New Guinea and Indonesia to the shape-shifting zebra shark that spends its youth striped and its adulthood spotted. In this episode, hosts Andrew Lewin and Dr. David Ebert sit down with Chris, a senior researcher who bridges evolutionary biology, population genetics, and applied conservation, to unpack why a single species can c

Seamounts are underwater mountains that rise at least 1,000 meters from the seafloor without breaking the surface, and they punch far above their weight biologically. Topographic upwelling pulls cold, nutrient-rich water up their slopes, fueling plankton blooms that draw fish, sharks, seabirds, and marine mammals, while their rocky surfaces give slow-growing corals and sponges a rare hard place to root in an otherwise soft-sediment deep sea. Roughly one in five seamount species are endemic, foun

Before he ever sat across a table from UN delegates, Matthew Gianni spent 10 years working as a commercial fisherman up and down both US coasts. Gillnetting for Spanish and king mackerel in Florida. Bottom trawling off central California, New England, and Florida for sole, redfish, hake, sablefish, shrimp, and other groundfish. Hook-and-lining for salmon and albacore tuna in Oregon and California. Running pots for Dungeness crab and dredging for deep sea scallops on Georges Bank. In today's epis

Science communication has a blind spot: it keeps putting the same faces in front of the microphone. In this episode, Andrew talks with Amy Weldon, host and executive producer of the podcast Blue Collar White Coat, about why she built an entire show around the people science coverage usually skips. Amy spent 15 years in science communications, starting at the National Aquarium in Baltimore, and now uses that background to track down the electricians, dive supervisors, ship repair technicians, and

YouTube has quietly become one of the best platforms for ocean science communication, and in this episode Andrew breaks down exactly why. Fresh off yesterday's 2,000-episode milestone and the new Pisces Oceans licensing agreement, Andrew explains why he's diving back into YouTube after stepping away last spring, including the launch of a brand new daily show, Ocean Decoded Live. Andrew walks through his own history with video, from the early days of Speak Up for Blue TV through burnout, a rebra

Today marks episode 2000 of How to Protect the Ocean, and Andrew is taking a break from the usual format to look back at how this show came to be. From an accidental start in 2010 to a name change driven by search engine optimization, to over 3 million downloads across 11 years, this episode traces the full arc of the podcast's history. Andrew also opens up about how podcasting reshaped his career. What started as a side project outside of work hours led to TV documentary appearances, podcast h

Podcasting has been part of Andrew Lewin's life for 11 years, and in this episode he explains why he thinks more people working in ocean science and conservation should be doing it too. He walks through what makes long-form audio and video different from the short clips discussed in yesterday's episode: the ability to sit with complex topics, tell a full story, and reach an audience that's multitasking, whether they're walking the dog, working out, or gardening while listening. Andrew gets spec

Walking sharks are one of the strangest small predators on the reef: pectoral fins built for crawling across coral flats at low tide, distributions so narrow some species live in a single bay, and a family tree that's still being filled in. In this episode, Andrew Lewin and Dr. David Ebert are joined by Jess Blakeway, a PhD candidate at the University of the Sunshine Coast, whose research on the distribution, ecology, and biology of walking sharks (genus Hemiscyllium) in Papua New Guinea has alr
