🪸 Happy World Reef Day! 🌊

Today, we celebrate coral reefs, some of the most beautiful, diverse, and important ecosystems on Earth.

Though they cover less than 1% of the ocean floor, reefs support around 25% of all marine life, protect coastlines, and sustain communities around the world.

But these ecosystems are under growing pressure from climate change, pollution, and many local and global stressors.

That’s why understanding, restoring, and protecting reefs matters more than ever.

💙 We protect what we love, and we love coral reefs.

“Water Bankruptcy.” It sounds intense, but it’s actually a tool for hope. 🌊💙

A new report from UN scientists (), authored by , suggests we stop using the word “crisis.”

A crisis is temporary. What many regions are facing is bankruptcy: a state where we have overspent our water budget for so long that the old normal is gone.

But here is the hopeful part: bankruptcy can be the beginning of restructuring.

For ocean lovers, this matters because the ocean is downstream of everything. Healthy reefs and coasts rely on freshwater flowing naturally from land to sea. When that cycle breaks upstream, the coast feels the loss.

We don’t need to be afraid of the data. We need to be honest about it.

Swipe through to see how “bankruptcy” can become the beginning of recovery.

New REEF Roundup episode is out now! 🌊

In this episode, we sit down with Briony Venn, Marine Campaign Organiser at the Bob Brown Foundation in Tasmania, for a powerful conversation about Antarctic krill fishing, marine campaigning, and what it takes to turn ocean concern into action.

Antarctic krill are a keystone species of the Southern Ocean, feeding whales, penguins, seals, seabirds, and entire Antarctic food webs. Yet more than 500,000 tonnes are harvested every year, even as climate change places growing pressure on the ecosystem.

Briony helps unpack the ecological stakes, the industry narratives around krill fishing, and the campaign strategies being used to challenge an expanding fishery.

The episode also includes a bonus conversation with Captain Paul Watson on Operation Krill Wars and recent direct action in the Southern Ocean.

If you care about Antarctic ecosystems, ocean advocacy, and the future of marine conservation, this is an episode worth listening to.

🌊New REEF Roundup episode is out now.

In this episode, we had the honor of sitting down with Dr. Andréa G. Grottoli, Distinguished Professor of Earth Sciences at The Ohio State University and inventor of the Underwater Zooplankton Enhancement Light Array, known as UZELA.

Drawing on over 30 years of research into coral feeding and bleaching physiology, Dr. Grottoli shares how her work led to the development of a technology designed to improve survival outcomes for corals in restoration efforts.

We explore what happens to corals during bleaching, why feeding matters for resilience, and how targeted innovation can support reefs facing growing environmental stress.

This is an insightful conversation at the intersection of coral biology, restoration, and blue technology.

🎙️ New Episode Out Now...

In this episode, we sit down with Dr. Sambuddha Misra, chemical oceanographer, associate professor at the Indian Institute of Science, and Chief Scientist at Alt Carbon.

At the center of this conversation is a simple but powerful idea: accelerating a natural geological process to remove CO₂ from the atmosphere.

Through Alt Carbon’s Darjeeling Revival Project, we explore how crushed basalt, rainwater, and atmospheric carbon interact to drive carbon removal, restore degraded soils, and create measurable environmental impact.

This episode examines the real-world challenges of implementation, from scaling operations to verifying carbon removal in complex natural systems.

Bonus Episode: Out Now 🎙🌊

In this special REEF Roundup episode, we partner with Jan Maisenbacher from the Ocean Collaborations podcast to sit down with Alice Guittard, a geographer and transboundary ocean management specialist who has spent the last five years with the Bridge Black Sea Project.

This conversation dives into one of the world's most fascinating marine ecosystems, bordered by six nations and fed by the watersheds of more the twenty others. We explore what it takes to collaborate across borders to protect a shared sea and prevent the "Tragedy of the Commons" from causing ecosystem failure.

We also examine how war can affect ecosystems and look at the logistical hurdles of attempting international scientific collaboration in the middle of an active war.

🎬 The Black Sea is a unique and beautiful place, and its shared nature provides a powerful example of how collaboration can make or break an ecosystem. That's the focus of our upcoming documentary, , created together with Director .gaze . We are in production now for a release later this year. Watch the trailer at www.alightintheblack.com and follow us to learn more.

Special thanks to Jan for facilitating, and to our new co-producer, Emily Pokou, for helping take the show to new heights.
