New Coral Gardens and Hydrothermal Vents Found in the Icy Depths of the Remote South Sandwich Islands
Hydrothermal Vents Found in the Icy Depths of the Remote South Sandwich Islands
An Ocean Census Flagship expedition and GoSouth team of scientists found suspected new species, discovered one of the island chain’s shallowest hydrothermal vents, and explored the deepest trench in the Southern Ocean.
Palo Alto, CA, USA — An international team of scientists on a recent 35-day deep-sea expedition to one of the most remote island chains in the world observed thriving polar ecosystems, discovered new hydrothermal vents, coral gardens, and many suspected new species. The Ocean Census Flagship expedition aboard Schmidt Ocean Institute’s research vessel Falkor (too) explored the South Sandwich Islands, including one of the coldest and most isolated submarine trenches on the planet, and also found evidence of explosive volcanism. This was the same expedition that filmed the first confirmed sighting of a juvenile colossal squid.
The expedition was part of the Nippon Foundation–Nekton Ocean Census program, the world’s largest initiative to accelerate the discovery of ocean life. The Ocean Census scientists led the species discovery efforts, uncovering a wide range of potentially new marine life — including corals, sponges, snails, sea urchins, benthic ctenophores, and sea stars. The exact number of new species will be announced later this year following an Ocean Census workshop, where taxonomic experts will formally assess and catalog the findings. The GoSouth team — a collaboration between the University of Plymouth (UK), GEOMAR (Germany), and the British Antarctic Survey (UK) — investigated the effects of geohazards, including tsunamis, volcanoes, and earthquakes.
“This expedition has given us a glimpse into one of the most remote and biologically rich parts of our ocean. This is exactly why the Ocean Census exists — to accelerate our understanding of ocean life before it’s too late,” said Dr. Michelle Taylor, head of science and expedition principal investigator at the Ocean Census, and senior lecturer at the University of Essex. “The 35 days at sea were an exciting rollercoaster of scientific discovery; the implications of which will be felt for many years to come as discoveries filter into management action.”
Mother Nature threw everything she had at the expedition, said Taylor, including a subsea earthquake, tropical storm force winds with hurricane-level gusts, eight-meter (26-foot) waves, and icebergs to navigate.
Located in the South Atlantic, the South Sandwich Islands are part of a rich mosaic of geologic features such as hadal zone trenches, underwater volcanoes, and spreading centers — features created by tectonic forces that have supported the evolution of species found nowhere else on the planet. It took eight days for the research vessel to travel to the islands from the port of Punta Arenas, Chile.
The GoSouth team, led by Co-Chief Scientist Dr. Jenny Gales, discovered two pockmarks in the mapping data of an underwater caldera — a bowl-shaped depression in the seafloor, left after a volcano erupts. Pockmarks can indicate hydrothermal activity. Using a “nested” approach, the team deployed Schmidt Ocean Institute’s remotely operated vehicle, SuBastian to map the pockmarks at a higher resolution and confirm the presence of vents.
The larger pockmark contained three hydrothermal vents, and the smaller contained one. Located at 700 meters depth (nearly 2300 feet), they are one of the shallowest hydrothermal vents to have been discovered near the South Sandwich Islands, and the only ones to be explored using a remotely operated vehicle. The tallest vent chimney was four meters (13 feet), making it about as tall as a basketball hoop. Each vent was covered with an array of life dependent on chemosynthesis, including sea snails and barnacles. Thriving coral gardens and large sponges were found in close proximity to the vents — an unusual observation, said Taylor.
“Discovering these hydrothermal vents was a magical moment, as they have never been seen here before,” said Gales, an associate professor in Ocean Exploration at the University of Plymouth (UK). “It’s an incredible discovery that provides valuable insights into the area’s tectonic activity. Making such a discovery is rare. It highlights the importance of ocean exploration and seafloor mapping.”
In addition to the vents, other notable observations during the expedition included:
- In the trench, scientists found snailfish eggs that had been laid on a black coral, as well as a potential new sea cucumber species;
- large pumice blocks, indicating that the South Sandwich Islands are capable of explosive volcanism;
- a vibrant coral garden located west of Saunders Island at a depth of 120 meters (394 feet);
- Capturing the first footage of Akarotaxis aff. gouldae, a species of dragonfish that was discovered two years ago.
“The challenging ocean and weather conditions and the isolated location of the South Sandwich Islands capture the imagination of the boldest explorers — often the closest humans to the vessel were on the International Space Station,” said Schmidt Ocean Institute’s Executive Director, Dr. Jyotika Virmani. “We are proud to have collaborated with Ocean Census in their mission to advance the discovery of marine life and GoSouth in their quest to better understand the geological nature of this dynamic corner of the world.”

Announcing the Winners of the 2025 Science Without Borders® Challenge
A Tribute to the Ocean’s Keystone Species:
Announcing the Winners of the 2025 Science Without Borders® Challenge
ANNAPOLIS, MD — The Khaled bin Sultan Living Oceans Foundation is proud to announce the winners of the 2025 Science Without Borders® Challenge, an international student art contest that promotes ocean conservation. This year’s theme, Marine Keystone Species, invited students to create artwork highlighting species that play a critical role in maintaining the structure and health of ocean ecosystems.
Open to primary and secondary school students 11–19 years old, the competition received an overwhelming response this year. Over 1,300 young artists from 75 countries submitted artwork—each piece a unique interpretation of a marine keystone species, from sea otters and mangroves to corals and sharks. These species may not always be the most numerous or well-known, but they have an outsized impact on their environment. Their presence helps maintain biodiversity, balance food webs, and support ecosystem resilience. If a keystone species is removed, the entire ecosystem could shift dramatically or collapse. Through their art, students explored these complex ecological relationships and made a compelling case for ocean conservation.
Artwork in the competition was judged in two categories based on age. The winning entries are not only beautiful pieces of artwork—they are a tribute to the animals that keep our ocean ecosystems in balance.
In the 15–19 age group, the first-place winner of the 2025 Science Without Borders® Challenge is Hyungjun Chin, with his enchanting piece, “The Keeper.” An 18-year-old student from the Republic of Korea, Hyungjun’s artwork depicts a sea otter eating sea urchins in a vibrant kelp forest, highlighting the otter’s role in protecting the kelp from overgrazing.
“Winning the Science Without Borders Challenge® means a lot to me,” said Hyungjun. “It feels incredibly rewarding to have my artwork recognized on an international level, especially when it’s about a topic I care deeply about—the environment. I wanted my artwork to show how every species has a role and how protecting even one can save many.”
Second place in the 15–19 category went to Kimin Kim of the Republic of Korea for her artwork, “Bridge Between Waters and Worlds.” Her piece highlights the importance of mangrove trees as habitat for species both above and below the waterline, and their role in purifying the water for nearby seagrass meadows.
Daniel Yu from Hackensack, New Jersey, claimed third place with “The Sea’s Yggdrasil,” a striking portrayal of mangroves as ecosystem engineers—stabilizing coastlines, preventing erosion, and filtering pollutants from the water to support surrounding marine life.
In the 11–14 age group, Gia Kim, age 12, from Los Angeles, California, earned first place for “Melting Grounds,” her powerful painting of krill—tiny but vital creatures that form the heart of the food web in the Arctic and Antarctic. Her artwork illustrates how the loss of such species, due to threats like climate change and ocean acidification, could lead to ecological collapse.
“I hope this piece raises awareness about our damaged ocean and what could happen if we continue to harm it,” said Gia. “This is our planet, and we can make a change, starting with our warming ocean.”
Second place in the 11–14 age group went to Kate Wang from Canada for “Seagrass Savior,” which illustrates how the large appetites of tiger sharks help protect fragile seagrass ecosystems.
Third place was awarded to Annie Douglas from The Bahamas for “The Beauty of Coral Reef,” celebrating reef-building corals. Although coral reefs cover less than 1% of the ocean floor, they support roughly 25% of all marine species, including over 4,000 kinds of fish.
Each of the winners will receive scholarships of up to $500 from the Khaled bin Sultan Living Oceans Foundation to celebrate their achievements and help them pursue their interests in art and ocean conservation.
Now in its 13th year, the Science Without Borders® Challenge continues to engage students in important ocean science and conservation topics through art. The Khaled bin Sultan Living Oceans Foundation created the competition to educate students around the world about the need to preserve our oceans and inspire the next generation of ocean advocates.
“The goal of this contest has always been to educate students about the ocean through art,” said Amy Heemsoth, Chief Operating Officer and Director of Education at the Foundation. “This year’s theme helped them understand how essential certain species are to the health of marine ecosystems. Their artwork serves as a powerful reminder of our responsibility to protect our oceans for future generations.”
The Khaled bin Sultan Living Oceans Foundation extends its heartfelt congratulations to all the winners and participants of the 2025 Science Without Borders® Challenge, and thanks them for using their creativity and passion to inspire positive change for our oceans.
