The Mystery of the Black Goo

The Mystery of the Black Goo

Why is a slimy substance made up of dead plankton and other organisms coating the floor of the Gulf of Mexico?

I got off the WeatherBird II mid way through the cruise in Pensacola, Florida. Five days later, an e-mail arrived from chief scientist David Hollander, subject line: "Yuck!"

As soon as it was back out on the water, the WeatherBird II headed to Perdido Pass, about two miles from Orange Beach, Alabama. When the team pulled up the multi-corer, they were stunned by what they found: the cylinders filled with pitch black, gelatinous goo that looks exactly like crude oil. But it didn’t act like oil: the scientists were able to wash it off their hands easily, and it smelled strongly of sulfur, not petroleum. "As a sedimentoloist I can tell you that none of us have ever seen anything like this in the Gulf of Mexico," Hollander says, "especially not in shallow water. It certainly didn’t belong there."

The location was also interesting. According to Hollander, "this exact area was subjected to over two months of continuous oiling of the shoreline region and the widespread use of dispersants in near-shore shallow waters."

Back at the University of South Florida laboratories, the experiments began. It turns out the black goo is made up of dead plankton and other organisms that adhered to each other. But why did all these life forms die? John Paul, a professor of biological oceanography, tested the waters from the mud and they came back, in his words, "toxic as all bejesus." So there has been some kind of poisoning, but was it BP? Or did these organisms run into some other poison in the gulf?

According to Hollander, it’s certain "that these unique sediments have accumulated within the past year and that their origin is contemporaneous with the timing of the oiling and use of dispersants" in the area.

Hollander’s tests are ongoing and definitive results will take weeks. All he knows is that a whole lot of marine organisms died and formed a "toxic marine tumble weed," rolling around on the ocean floor until the Weatherbird team happened to poke it. Which kind of makes you wonder: what else are those supposedly healthy waves hiding?

Independent journalism relies on your support


With a hostile incoming administration, a massive infrastructure of courts and judges waiting to turn “freedom of speech” into a nostalgic memory, and legacy newsrooms rapidly abandoning their responsibility to produce accurate, fact-based reporting, independent media has its work cut out for itself.

At The Nation, we’re steeling ourselves for an uphill battle as we fight to uphold truth, transparency, and intellectual freedom—and we can’t do it alone. 

This month, every gift The Nation receives through December 31 will be doubled, up to $75,000. If we hit the full match, we start 2025 with $150,000 in the bank to fund political commentary and analysis, deep-diving reporting, incisive media criticism, and the team that makes it all possible. 

As other news organizations muffle their dissent or soften their approach, The Nation remains dedicated to speaking truth to power, engaging in patriotic dissent, and empowering our readers to fight for justice and equality. As an independent publication, we’re not beholden to stakeholders, corporate investors, or government influence. Our allegiance is to facts and transparency, to honoring our abolitionist roots, to the principles of justice and equality—and to you, our readers. 

In the weeks and months ahead, the work of free and independent journalists will matter more than ever before. People will need access to accurate reporting, critical analysis, and deepened understanding of the issues they care about, from climate change and immigration to reproductive justice and political authoritarianism. 

By standing with The Nation now, you’re investing not just in independent journalism grounded in truth, but also in the possibilities that truth will create.

The possibility of a galvanized public. Of a more just society. Of meaningful change, and a more radical, liberated tomorrow.

In solidarity and in action,

The Editors, The Nation
