Speak Up for Blue Podcast Network

A new documentary called Descent – Into the Blue starts airing on public television stations nationwide on September 1, 2026. It's narrated by Peter Coyote, directed by Rory Fielding, and one of its central voices is Mike Goldberg, co-founder of the Florida Keys coral restoration nonprofit I.CARE and owner of Key Dives in Islamorada. Andrew sits down with Mike for the full, unedited version of the conversation this week's four solo episodes have been building toward: 30-plus years running a dive

Six months into your ocean project, you realize nobody knows who it's for. Now you're untangling years of work instead of moving forward. In this episode, host Andrew Lewin sits down with Natalie Gilson, co-CEO of Pisces Oceans, to talk about the cost of treating communications as an afterthought. Whether you're running a nonprofit, a startup, or an academic research project, Natalie makes the case that communications strategy belongs at the start, not six months or a year down the road once th

Most coral restoration groups check on a sample of what they've planted, often around 20 to 30 percent, and report that sample as if it represents everything in the water. I.CARE checks on all of it. Every single coral outplant gets monitored at one week, one month, 90 days, then one, two, and three years, with no substitute and nothing left unaccounted for. That rule was built in by co-founders Mike Goldberg and Dr. Kylie Smith before I.CARE ever planted its first coral, and Mike frames it as a

Coral nurseries need constant maintenance, and that maintenance is expensive and relentless. When Andrew talked to Mike Goldberg, co-founder of I.CARE, his answer wasn't to hire more staff. It was to let paying customers do it for the fun of it. Mike owns a dive shop in the Florida Keys, so the paying customers are scuba divers, and over the years he's built a funding model so small that nobody has ever really complained about it. None of that makes sense until you understand what coral actuall

Eustacy is a word used to describe worldwide changes of sea level. This is a new word for us: even though it seems we live in a eustatic world. We're using this newly-discovered word to distill the five areas of our existence where the ocean matters most: fresh water, the ocean-fresh water continuum, energy, food, health, and exchange.

Mike Goldberg had over 10,000 dives and decades running a dive shop in the Florida Keys, enough time to have seen the reefs at their pristine best. Then came a coral bleaching event in 2008, and a few years later, Stony Coral Tissue Loss Disease, a still-unexplained outbreak that's killed coral tissue outright across more than 20 of Florida's roughly 45 stony coral species since 2014. At one point his wife told him directly: the reef isn't what it used to be, and it's not getting better. Get out

This year, most of the coral on the planet went through heat stress severe enough to bleach it. That's not a rounding error: 84 percent of the world's reef area, across the Pacific, Atlantic, and Indian Oceans, and NOAA had to add three brand-new alert levels to its Coral Reef Watch scale because the existing one had no category for what was happening. In this episode, Andrew breaks down exactly where global coral reefs stand right now: how the fourth global mass bleaching event on record got de

Dr. Issah Seidu didn't set out to become West Africa's first dedicated shark and ray scientist. He started his career studying dragonflies, damselflies, amphibians, and even elephants and crocodiles as a terrestrial wildlife biologist in Ghana, a country whose university programs, like most in the region, simply didn't study marine species. That changed on a visit to his uncle, a fisherman in a coastal community, where he watched sharks and rays being landed and sold on the beach and realized no

Holly Koehler has spent almost thirty years in rooms most people never think about: windowless UN offices in New York, the FAO in Rome, and what she calls "oftentimes very boring hotel ballrooms around the world," where countries hash out how the ocean actually gets managed. She's the Vice President of Policy and Outreach at the International Seafood Sustainability Foundation (ISSF), and before that she spent thirteen years at the U.S. State Department's Office of Marine Conservation, chairing i

Some of the world’s greatest innovations were born from unexpected conversations rather than scheduled meetings. Ideas often emerge not during presentations but in hallways, kitchens, cafés, and shared lunch tables. This week we're discussing Thor Sigfusson's new book "The Incredible Coffee Machine, Where Mission, Space and Innovation Meet" and the ways informal encounters can reshape entire industries.
