Open-source intelligence (OSINT) tools are changing the way we can monitor the ocean. The @pulitzercenter.org is hosting a webinar on Tues, Sept 9, at 12pm US ET, for investigative journalists, environmental reporters & data enthusiasts looking to deepen their reporting using OSINT.

This wraps up my @pulitzercenter.org project on how climate change is playing out in the ocean. I'm really grateful for their support, and grateful to my editors, collaborators and above all the many many sources who spoke to me over the past year. I'll thread the other 3 stories below.

Highly recommend to any journalists with an ocean story to tell! You get the rare gift of time (and travel $) to pursue ambitious stories. You also learn a ton from the Pulitzer Center's data and research team, as well as from your cohort -- who will be impressive journalists from around the world!

Efforts by countries like Russia and Iran to circumvent Western sanctions on their petroleum have spawned a black market at sea, leading to a surge in human rights abuses of the seafarers recruited.

This is such an important story for the ocean. Losing these sea stars meant losing whole forests of kelp, whole ecosystems. And although scientists have just identified the bacteria behind the disease, as this story points out, they already knew there was a "co-conspirator" in rising temperatures.

Craig Welch @craigwelch.bsky.social · Aug 4

Sea stars—26 species—have been dying by the billions from Mexico to Alaska, their arms tearing off, their bodies dissolving, w/huge consequences for the sea.

Experts finally figured out why— and gave @biographic.bsky.social exclusive access.

Can we save them? www.biographic.com/unmasking-th...

After a decade of carnage, we finally know what’s devastating sea stars along North America’s West Coast. Does that mean scientists can save them?

Update: Our friend @alecluhn.bsky.social was found alive this morning!

He is in good health with some injuries to his leg/foot. He is at a hospital in Bergen now. Thank you to the Norwegian helicopter team who found him and all the volunteers who searched in bad conditions. ❤️

Clare Fieseler, PhD @fieseler.bsky.social · Aug 5

My friend Alec is missing. Please share this widely incase it reachers any hikers who have seen him over the past 5 days during his solo hike in a Norwegian national park.

David Ho @davidho.bsky.social · Aug 5

I’m sharing this hoping that someone hiking the same route in Norway might see this. Let’s find @alecluhn.bsky.social!

In case I have any followers in Norway -- my colleague Alec Luhn is missing after a solo hiking trip in the Folgefonna / Nedre Buarbreen area. The Red Cross is searching, but if anyone has seen Alec by chance, they can call the local police at 02800 or email [email protected] with info.

If you're in the Northern Hemisphere, chances are you've endured a heatwave. But have you considered what this extreme heat looks like beneath the surface?

Big thanks to the @pulitzercenter.bsky.social for sending me to France! Aside from reporting on the conference, I was able to meet and learn from Ocean Reporting Network colleagues from around the world. And thanks also to my colleague in the NYT Paris bureau Daphné Anglès for her invaluable help.

Interestingly, I discovered that the U.S. representatives sent by President Trump - including White House advisor Ed Russo - are more engaged with ocean issues than you might think. Together with Salesforce CEO & conference sponsor Marc Benioff, he called on countries to restore coral reefs.

Deep sea mining - which the U.S. is trying to unilaterally permit in international waters - was a flash point. So was bottom trawling, highlighted by the new David Attenborough film. Activists called on co-host France to ban trawling in its marine protected areas, and were ultimately disappointed.

Delger Erdenesanaa @edelger.bsky.social · Jun 16

There was progress toward ratifying the Biodiversity Beyond National Jurisdiction agreement - aka the high seas treaty - with 19 more countries ratifying last week. Once active, the treaty would offer a path toward protecting stretches of the high seas. 10 more ratifications are needed.

At U.N. Conference, Countries Inch Toward Ocean Protection Goal

Easy-to-miss news amid the chaos: At the 3rd UN ocean conference, countries declared 20+ new marine protected areas, but thousands more are needed to reach a goal of protecting 30% of the ocean by 2030. Questions also remain about how meaningful these protections are. www.nytimes.com/2025/06/14/c...

I'm more grateful to my scientist sources than ever. And if anyone out there working on climate, ocean and marine life issues affected by cuts to NOAA and other federal agencies wants to talk, please reach out (Signal: edelger.10). Happy to talk off the record first, discuss anonymity, etc.

I started reporting this -- on climate change and the smallest, most numerous residents of the ocean -- before the election. Amid the chaos, I think it's still important to tell the big picture story of what's happening to the planet. www.nytimes.com/2025/03/03/c... 🧪

Scientists are gaining new insights into how plankton supports life on Earth — just as climate change is changing everything.
