A sea change from London to 'Jurassic Park'
In 2013 Kelly Green swapped her busy life as a flight attendant to move to Tristan Da Cuhna - part of a volcanic archipelago in the South Atlanic Ocean and the most remote inhabited island in the world. It's only possible to get to by ship from South Africa a few times a year. Despite the isolation, Kelly Green says it was a love story, island life, and the wildlife which has made the tiny isle her forever home. Producer: Joanna Crothers

The South Atlantic Anomaly (SAA) has emerged as a focal point of scientific intrigue and concern. This vast region of weakened magnetic field over South America and the South Atlantic Ocean presents a unique challenge for NASA and the global scientific community. Originating from complex processes within Earth's core, the SAA is not only a fascinating natural phenomenon but also a critical area of study due to its potential impact on space technologies. As the anomaly evolves, it becomes imperative to understand its mechanisms and anticipate the challenges it presents to our technological infrastructure. Deep Origins and Complex Mechanisms At the heart of NASA's concerns lies the South Atlantic Anomaly (SAA), a geomagnetic phenomenon both captivating and concerning. This immense region is characterized by a significant reduction in magnetic intensity compared to its surroundings. Far from being a mere scientific curiosity, this weakness acts as a breach in our natural protective shield, allowing high-energy solar particles to dangerously approach Earth's surface. The origins of the SAA are intricately linked to the geodynamo, a complex process occurring in Earth's outer core. Here, the movement of molten iron and nickel generates the magnetic field that envelops us. However, this generation is not uniform. Two primary factors contribute to the formation of the SAA: the tilt of Earth's magnetic axis relative to its rotational axis and the influence of a massive dense structure known as the African Large Low Shear Velocity Province, located about 1,800 miles beneath the African continent. These factors disrupt the magnetic field generation in this region, leading to a local polarity reversal within Earth's magnetic field, further weakening the dipole field intensity in this specific area. 'NASA Uncovers Moon's Hidden Secret': Sun's Solar Wind Revealed as Critical Source of Lunar Water in Stunning Discovery A Threat to Space Technology This magnetic vulnerability poses significant risks to space technology. Satellites traversing the SAA are exposed to high levels of energetic protons, which can cause single event upsets (SEUs). These incidents can lead to temporary malfunctions, data corruption, or even permanent damage if critical systems are affected. To mitigate these risks, many satellite operators take preventive measures, such as shutting down non-essential systems when passing through the anomaly. Even the International Space Station (ISS) crosses the SAA on each orbit. While its shielding effectively protects astronauts, external instruments remain more vulnerable. Bryan Blair, deputy principal investigator for the GEDI instrument on the ISS, reports occasional 'glitches' and resets, resulting in a few hours of data loss each month. Other missions, like the Ionospheric Connection Explorer (ICON), also closely monitor the SAA and adjust their operations accordingly. 'Nasa Sounds the Alarm': Massive Anomaly Spreads Across Earth, Scientists Trace It to Mysterious Forces Deep Beneath the Surface Dynamic Evolution and Challenges The South Atlantic Anomaly is far from static. Recent data, particularly from the ESA's Swarm constellation and historical measurements from NASA's SAMPEX mission, confirm several alarming trends. The anomaly is slowly drifting northwest, expanding in surface area, and, as observed since 2020, beginning to split into two distinct lobes, creating two centers of minimum magnetic intensity. This bifurcation increases the number of hazardous zones for spacecraft and complicates the task of scientists developing predictive models of geomagnetic conditions. Understanding the changing morphology of the SAA is crucial for the safety of current and future satellites. As Terry Sabaka of NASA emphasizes, these developments necessitate continuous monitoring and adaptation in satellite operations to mitigate potential disruptions. 'NASA Says We're on the Brink': Alarming New Report Reveals Imminent Emergency Crash Risk for the Entire Space Station Anticipating the Invisible To refine their understanding and predictions, NASA combines satellite data with simulations of Earth's core dynamics. These inputs feed global models like the International Geomagnetic Reference Field (IGRF), which track the evolution of Earth's magnetic field. These models are essential not only for planning space missions but also for gaining a better grasp of our planet's internal structure. The approach resembles weather forecasting but on much longer timescales, allowing scientists to estimate the secular variation—the slow yet persistent changes in the magnetic field over years and decades. While the current evolution of the SAA is unprecedented in the space era, geological records suggest that such anomalies are not exceptional over long timescales. It is important to note that, according to scientists, the current SAA is not an early indicator of a magnetic pole reversal, a natural but rare phenomenon occurring over hundreds of thousands of years. Thus, studying the SAA remains a vital research area, crucial for protecting our orbiting technologies and deepening our understanding of the profound forces driving our planet. As the South Atlantic Anomaly continues to evolve, the scientific community remains vigilant in its efforts to understand and mitigate its impact. With its potential to disrupt satellite operations and influence our understanding of Earth's magnetic field, the SAA poses intriguing questions about the future of our planet's magnetic dynamics. How will these changes shape our technological and scientific pursuits in the years to come? Our author used artificial intelligence to enhance this article. Did you like it? 4.4/5 (21)

Coral gardens and volcano vents: See what scientists found in the icy depths of the Southern Ocean
Scientists on board a deep-sea expedition to the South Sandwich Islands near Antarctica have returned with a treasure trove of photos of previously unseen marine life. They found coral gardens, hydrothermal vents and many suspected new species while exploring around the island chain, including in the deepest trench in the Southern Ocean. The same international team, aboard Schmidt Ocean Institute's research vessel Falkor (too), made headlines last month with their world-first footage of a colossal squid. And in January, they were in the right place at the right time to explore the seafloor when a Chicago-sized iceberg broke away from an ice shelf in Antarctica. But there were many more 'magic moments' on the 35-day deep-sea expedition to this extremely biodiverse part of the ocean. '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,' says Dr Michelle Taylor, head of science and expedition principal investigator at the Ocean Census - the world's largest initiative to accelerate the discovery of ocean life. These remarkable photos take us along for the ride. Related What are milky seas? 400 years of sailors' stories are shedding light on ocean bioluminescence Located in the South Atlantic, the South Sandwich Islands are part of a rich mosaic of geologic features. These include hadal zone trenches (the deepest region of the ocean), underwater volcanoes, and spreading centres - 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. On board were Ocean Census scientists, who led efforts to discover new species, and researchers from GoSouth, a collaboration between the UK's University of Plymouth, the British Antarctic Survey and Germany's GEOMAR, tasked with investigating the effects of geohazards, including tsunamis, volcanoes, and earthquakes. Related Rare snail that can 'slurp up earthworms like noodles' caught on camera laying an egg from its neck 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. Since pockmarks can indicate hydrothermal activity, the team deployed the vessel's remotely operated vehicle (ROV) SuBastian to map the pockmarks at a higher resolution. The robot confirmed the presence of hydrothermal vents - fissures from which geothermally heated water rises - finding three on the larger pockmark, and one on the smaller one. Located at a depth of 700 metres, they are some of the shallowest hydrothermal vents to have been discovered near the South Sandwich Islands. The tallest vent chimney was four metres - about as tall as a basketball hoop. 'Discovering these hydrothermal vents was a magical moment, as they have never been seen here before,' says Dr Gales, an associate professor in Ocean Exploration at the University of Plymouth. '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.' Each vent was covered with an array of life dependent on chemosynthesis (producing food using inorganic substances without sunlight), including sea snails and barnacles. Thriving coral gardens and large sponges were also found in close proximity to the vents - an unusual observation, according to Dr Taylor. Related OceanXplorer: On board the billionaire's research vessel broadcasting from the deep sea Meanwhile, Ocean Census scientists uncovered a range of potentially new marine life - including corals, sponges, snails, sea urchins, sea stars and benthic (sea bottom) ctenophores, which have gelatinous bodies. A thriving coral garden located west of Saunders Island at a depth of 120 metres is pictured in one of the most breathtaking photos from the expedition. The exact number of new species will be announced later this year when experts have had time to formally assess and catalogue the findings. But they include a possible new sea cucumber species - marine invertebrates so-named for their soft cylindrical bodies. These creatures play a crucial role in benthic ecosystems by recycling nutrients, and are well-adapted to the cold Antarctic environment. During a dive in the South Sandwich Trench - one of the coldest and most isolated submarine trenches on the planet - the team also spotted snailfish eggs laid on a black coral, a previously unknown behaviour. They also captured the first footage of Akarotaxis aff. gouldae, a species of dragonfish that was discovered only two years ago. And found large pumice blocks, indicating that the South Sandwich Islands are capable of explosive volcanism. Mother Nature threw everything she had at the expedition, says Dr Taylor, including a subsea earthquake, tropical storm force winds with hurricane-level gusts, eight-metre waves, and icebergs to navigate. '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,' says Schmidt Ocean Institute's executive director, Dr Jyotika Virmani.

Scientists Take First Ever Video of Colossal Squid in the Wild... With One Comical Issue
An international team of scientists from the Schmidt Ocean Institute have captured the first ever footage of a colossal squid — the terrors of the sea that are legendary for both their monstrous proportions and elusiveness — roaming in its natural habitat. But to say it's a big discovery might be misleading. Found lurking in the depths of the South Atlantic Ocean, the specimen is a juvenile mollusk, measuring barely a foot in length. With a transparent body, you might mistake it for some form of jellyfish at first. Mainly, it's the tiny tentacles that betray its true identity. It's no Kraken sighting, in other words. But so rare are these deep sea predators that any footage at all is invaluable. And besides, witnessing one as a baby isn't without its charm or scientific insight. "I actually love that this is our first glimpse of what will become a true giant," Kat Bolstad, a cephalopod biologist at the Auckland University of Technology who helped verify the video, told The New York Times. "It's exciting to see the first in situ footage of a juvenile colossal and humbling to think that they have no idea that humans exist," Kat added in a statement, per NPR. The footage was captured using a remotely operated vehicle dubbed SuBastian, at a depth of around 2,000 feet in March. Researchers on the expedition sent the footage to Bolstad, who confirmed that the specimen on display was indeed the famed creature, albeit in miniature. Colossal squids inhabit the cold depths of the Antarctic seas. As adults, they can grow up to 23 feet long — and perhaps close to twice that if you measure from tip to the ends of their tentacles — and weigh around 1,100 pounds. They shouldn't be confused with giant squids, which grow to similar lengths but are slenderer and less heavy, favoring more temperate waters. The colossal squid's existence was first discovered secondhand, through their chewed-up remains found in the stomach of a sperm whale in 1925. It wasn't until 1981 that a living full adult specimen was caught accidentally by fishermen. And nearly a century on, we still have a lot to learn about these mysterious creatures, which may in fact be trying to avoid humans. "They're very aware of their surroundings, because any disturbance in the water column around them might mean a predator," Bolstad told the NYT. Fully grown colossal squids boast the largest eyes in the animal kingdom, at roughly the size of a basketball, making them extremely adept at spying both prey and predators in the dark waters they call home. Finding more won't be easy, but this discovery is an encouraging reminder that it's possible. With any luck, the next one that the team spots will live up to its behemoth reputation. "I can't wait to see what a live adult colossal squid looks like, at home in the deep sea where it belongs," Bolstad told the NYT.
