Scientists make incredible discovery after exploring newly revealed section of seafloor: 'We seized upon the moment'
An iceberg the size of Chicago broke away from an Antarctic ice shelf in January — an alarming indicator of our changing climate.
Fortunately, an international team of researchers found a way to turn this gargantuan lemon into lemonade: they used the opportunity to explore a never-before-seen section of the seafloor.
What they found was nothing short of amazing.
As Schmidt Ocean Institute detailed, the expedition was part of the Challenger 150 global cooperative. This program conducts deep-sea biological research intended to better understand how to sustainably manage the deep ocean.
The initial mission was to study the seafloor around where this massive section of ice shelf met the Bellingshausen Sea. However, plans rapidly shifted when the approximately 209-square-mile iceberg broke off, revealing a massive section of the seafloor that was previously inaccessible.
"We seized upon the moment, changed our expedition plan, and went for it so we could look at what was happening in the depths below," expedition co-chief scientist Dr. Patricia Esquete said, per the Schmidt Ocean Institute.
SuBastian, a remotely operated vehicle (ROV) designed to safely explore deep waters, plunged to a depth of around 1,300 meters.
The ROV discovered a vast ecosystem of underwater plant and animal life. Among them were sea sponges, anemones, octopi, icefish, and giant sea spiders that may have been thriving down there for centuries.
"We didn't expect to find such a beautiful, thriving ecosystem," Dr. Esquete said. "Based on the size of the animals, the communities we observed have been there for decades, maybe even hundreds of years."
What amazed the research team most was how this ecosystem was capable of thriving without the help of nutrients raining down from the water above. They theorized that ocean currents may be responsible for providing such a vast ecosystem with the resources it requires.

There's no doubt studying the seafloor is fueled in part by sheer wonder for the array of life on our planet — but that's not the only thing driving it.
Understanding how this vast, unseen part of the planet operates can better inform us on how to protect the environment. With this knowledge, we can support these ecosystems, better manage resources, assess human impact, and more.
Similar deep-sea research is being conducted elsewhere. An expedition in Papua New Guinea's "rainforest of the ocean" uncovered several new species, affording conservationists a greater understanding of how to protect and manage this crucial section of the deep sea.
In New Zealand, a similar expedition discovered a new species of sea squirt. It's believed that studying these fascinating filter feeders can potentially improve human immune systems and even reverse signs of aging.

Photo courtesy of NASA June 5 (UPI) -- One of NASA's top ozone depletion and air pollution scientists, credited with enhancing local air pollution measurement tools and dozens of other climate related research advancements, has died at the age of 80. Dr. Stanley Sander was broadly recognized for his work on research on atmospheric chemistry at the Jet Propulsion Laboratory where he started his career in 1971. "Stan made foundational contributions to our understanding of stratospheric ozone depletion, tropospheric air pollution, and climate science related greenhouse gases," a statement from NASA about his death said. Sander's work on laboratory measurements was used to help other scientists reach consensus on a host of environmental issues, including developing tools to measure air quality and establish environmental policies. He also studied the chemistry of methane on Mars, halogen gases on Venus and hydrocarbons in Titan's atmosphere. "Stan's scientific output was vast," the NASA statement continued. "He authored over 180 peer-reviewed publications, beginning with his 1976 paper on sulfur dioxide oxidation. His work spans major aspects of atmospheric chemistry -- from chlorine, bromine, and nitrogen oxides to sulfur compounds and peroxides." NASA said Sander's influence went beyond the hard sciences and into mentorship of up-and-coming scientists. He led 40 post-doctoral students, more than two dozen graduate students and undergraduate students in their pursuits of understanding atmospheric chemistry. "Those of us lucky enough to be fostered by Stand in this capacity will also remember his kindness first approach and steadfast resolve in the face of challenges," the release said. Sander was awarded several meritorious achievement awards, including two NASA Exceptional Achievement Medals and a NASA Exceptional Service Medal.

How a supertiny crustacean makes life work in the Southern Ocean
Reporting in this article is presented by the National Geographic Society in partnership with Rolex under the National Geographic and Rolex Perpetual Planet Ocean Expeditions. One night last December, National Geographic Explorer Kim Bernard was stirring her Earl Grey tea in the galley of a research ship off the coast of Antarctica, preparing for a long night of observing a remotely operated vehicle as it surveyed the seafloor. When the marine ecologist looked up to a monitor showing a live video feed sent by the ROV from a depth of more than 3,000 feet in the Southern Ocean's murky waters, something caught her attention. 'I see this tiny little thing come in on the right-hand side of the screen and dart out,' she said. To the other scientists aboard, it probably looked like organic debris wafting down. But Bernard, 46, has been studying krill for 15 years and knows how the shrimplike crustaceans twirl in the water column and bolt backward when startled. That familiar movement sent her running down two flights of stairs to the ship's control room. Collected specimens from the seafloor. When she arrived, she saw the action on the seafloor being broadcast on a large bank of monitors, and she spotted a handful of individual krill spread out on a hydrothermal vent, a fissure in the ocean crust where hot magma and seawater meet and create a mineral-rich environment that attracts a host of organisms. For Bernard, a professor of biological oceanography at Oregon State University, finding krill here represented a momentous discovery. 'I kind of lost my mind,' she recalled. It was the first time the animal had been observed on a vent. (Why penguin poop makes krill swim for their lives.) Antarctic krill are a keystone species that allows everything else in the Southern Ocean to flourish. If Bernard could learn more about their habitat on the seafloor, her research could inform our understanding of virtually every predator on this hard-to-reach continent, from emperor penguins to blue whales. Any new behavior from such a foundational animal has the potential to affect the entire food chain above it. That night in the control room, aboard the research vessel from Schmidt Ocean Institute, Bernard soon realized all the krill were females carrying eggs. The species usually releases eggs higher in the water column. What makes it worth the risk to travel so far at that stage in reproduction? Were they feeding on the bacteria covering the vent? She asked the operator to use the ROV's special suction arm and gather a few of the crustaceans. This was also a first. Bernard isn't aware of any researchers who have collected specimens at that depth. She has since sent stomach and tissue samples out for analysis. (Scientists discover creatures living beneath the bottom of the deep sea.) Aboard the expedition vessel Bernard had access to tools like video cameras and a remotely operated vehicle to observe krill in the Southern Ocean. Bernard's work on the expedition, which was supported by the National Geographic Society and Rolex Perpetual Planet Expeditions, is part of an ambitious project that's sending nearly two dozen scientists to all five oceans. Their efforts will be the subject of a series of stories in National Geographic as they search for new insights—like, say, the presence of krill in underexplored places. In Antarctica, the species is more than just a vital part of the food chain. Krill are also a carbon sink, eating phytoplankton that have absorbed CO2 and then excreting pellets to the seafloor, where it can take thousands of years for the absorbed carbon to resurface. However, there are new pressures on the species from both humans and climate change. Krill are increasingly harvested as aquaculture feed, and the animals' oil is highly sought after as a dietary supplement. Meanwhile, as sea ice continues to melt, larval krill are losing an important habitat where they can hide from predators, find food, and develop into adults. Bernard hopes her ongoing research and future insights from this discovery will protect this tiny animal that so much life relies on. 'There's a thriving mass of life down there,' she said, 'and all of it depends on krill.' The ROV was able to collect specimens from the seafloor that were later dried for analysis. A version of this story appears in the July 2025 issue of National Geographic magazine.
