The figures didn’t add up for years. Climate models had consistently predicted that more ancient, carbon-laden water would churn up from the deep, flooding the surface and gradually impairing the ocean’s capacity to absorb new CO2, as global warming increased and westerly winds over the Southern Ocean strengthened. Based on decades of knowledge about oceanography, the projection made sense. Nevertheless, the anticipated decrease in the Southern Ocean’s carbon absorption was not evident in the actual observational data. Researchers at the Alfred Wegener Institute in Germany have now published a study in Nature Climate Change that explains why, and in a…

The idea that science can find a world—a living, breathing, biologically impossible world—and then watch it vanish before it is fully comprehended is incredibly unsettling. Deep-sea hydrothermal vents are those boiling, mineral-spewing fissures in the ocean floor that have silently supported life for millions of years without anyone on the surface realizing they existed. Jack Corliss and Tjeerd van Andel’s descent into the Galápagos Rift in a small research submersible named Alvin in February 1977 marked the first documented encounter. Giant tubeworms, white crabs, thick bacterial mats covering the seafloor, and entire communities of organisms flourishing in the absence of…

Antarctica seemed to be the only dependable exception on Earth for many years. The sea ice encircling the southern continent continued to expand while the Arctic was clearly disintegrating, with shrinking summers, thinning ice, and retreating coastlines. Scientists took note of it, discussed it, and secretly hoped it was comforting. It didn’t. Antarctica’s sea ice unexpectedly tumbled off a cliff in 2016. And it hasn’t returned yet. What took place? For almost a decade, the scientific community has been debating this issue, which raises unsettling questions about our true understanding of the planet we are meant to be observing. The…

Climate scientists worked quietly confidently about the Southern Ocean for about thirty years. The numbers made it very evident that it was absorbing a significant amount of carbon. It was verified by models. Datasets supported it. The broader understanding of the global carbon cycle was constructed, at least in part, on the basis of this settled assumption. The type of paper that forces readers to read the abstract twice then emerged. A team led by Guorong Zhong from the Chinese Academy of Sciences discovered something unsettling in a 2024 publication in Communications Earth & Environment: the Southern Ocean’s carbon sink…

A certain type of money comes in stealthily and transforms everything. Unlike announcements from Silicon Valley, the $15 million grant that Scripps Institution of Oceanography received earlier this March from the Fund for Science and Technology is not ostentatious. No launch of a product. No response from the stock ticker. Just scientists, a strategy, and access to regions of the planet that most people will never see and, to be honest, have hardly given much thought to. Launched just last year, the Fund for Science and Technology, which is funded by the late Microsoft co-founder Paul G. Allen’s estate, aims…

The lack of interest in DePTH-GPT outside of scientific circles is somewhat unsettling. When China introduced it in November 2025, the news spread around the world for a day or two before the discussion largely moved on. That is incorrect. This is not a specialized research tool; rather, it is a sign of the direction and leadership of ocean science. Deep-sea Perception, Thinking and Habitat GPT, or DePTH-GPT for short, is an artificial intelligence model designed to handle the kinds of data that have always made deep-sea research so challenging: video footage from submersibles traveling through pitch-black water, acoustic recordings…

The way the ocean retains centuries’ worth of climate memory in its icy, dark layers, regardless of whether anyone is paying attention, is something subtly amazing. Oceanographers at the Scripps Institution of Oceanography in La Jolla, California, have been observing for many years. They are now going to take a closer look thanks to a $15 million donation from a private foundation founded on the wealth of the late Microsoft co-founder Paul Allen. The Fund for Science and Technology, a foundation established only a year ago with a pledge to invest at least $500 million in research over the following…

In lengthy campaigns, there comes a time when the goal you’ve been working toward for years suddenly becomes a reality rather than a goal. The world’s oceans reached that point on January 17, 2026. Formally known as the Agreement on the Conservation and Sustainable Use of Marine Biological Diversity of Areas Beyond National Jurisdiction, the High Seas Treaty came into effect. For the first time in human history, international waters—those enormous expanses of ocean that don’t belong to any one nation and were previously essentially unprotected—have a legal framework. Given the scope of what was accomplished, it’s difficult to ignore…

Scientists believed they understood the origin of methane for the majority of the previous century. wetlands. paddies of rice. cow stomachs. Lake bottom sediments are deep and oxygen-starved. Methane could form anywhere there was a lack of oxygen. However, the open ocean’s surface never quite matched that image, and the contradiction lingered for decades, slightly embarrassing, like a stain on a textbook that no one wanted to thoroughly clean. A group at the University of Rochester claims to have finally identified the cause. The response, which was published in PNAS this spring, is more bizarre and unsettling than most climate…

No one anticipated the coral graveyard that lies nearly a kilometer below the surface off the coast of the Galápagos. Not the visitors who come each year to see the tortoises and finches. Nor do the majority of marine biologists. Until recently, scientists believed that areas like these were the stable ones, the sections of the ocean that just survived while everything above them burned and bleached. The reefs are located in cold, dark water where sunlight never really reaches. It’s beginning to seem like a generous assumption. Recent research published in PNAS by a team at the University of…
