UK scientist's Antarctic remains found after 66 years, closing a frozen chapter

UK scientist's Antarctic remains found after 66 years, closing a frozen chapter

Malay Mail20 hours ago
LONDON, Aug 12 — The remains of a British meteorologist who died in an Antarctic expedition in 1959 have been recovered six decades later from a glacier, the British Antarctic Survey said Monday.
They were identified by DNA-testing as those of Dennis 'Tink' Bell, who died aged 25 when he was working for the Falkland Islands Dependencies Survey, which became the British Antarctic Survey (BAS), the UK's polar research institute.
Bell died on Admiralty Bay on King George Island, located 120 kilometres off the coast of Antarctica on July 26, 1959.
He was stationed on the island for a two-year assignment at a small UK research base.
Bell and three other men had set out to climb and survey a glacier, when he fell through a crevasse — a deep chasm in the ice. His body was never recovered.
The remains, which were exposed by a receding glacier, were found on January 19 by a team from the Henryk Arctowski Polish Antarctic Station.
'This discovery brings closure to a decades-long mystery and reminds us of the human stories embedded in the history of Antarctic science,' said BAS director Jane Francis.
The bone fragments were carried to the Falkland Islands by the BAS Royal Research Ship Sir David Attenborough, and then brought to London for DNA testing.
Alongside his remains, the Polish team also found over 200 personal items including radio equipment, a flashlight, ski poles, an inscribed wristwatch and a Swedish-brand knife.
Bell's brother David Bell, who lives in Australia, said the discovery after 66 years left him and his sister 'shocked and amazed'.
'Dennis was the oldest of three siblings and was my hero as he seemed to be able to turn his hand to anything,' said his brother.
Francis said the confirmation of the remains 'is both a poignant and profound moment for all of us at British Antarctic Survey'.
Bell 'was one of the many brave … personnel who contributed to the early science and exploration of Antarctica under extraordinarily harsh conditions,' she added. — AFP

Seals sing ‘otherworldly' songs structured like nursery rhymes

Male leopard seals sing songs with five notes to broadcast their individual identity, researchers suggest. (Envato Elements pic) PARIS : When male leopard seals dive down into icy Antarctic waters, they sing songs structured like nursery rhymes in performances that can last up to 13 hours, scientists said on Thursday. The Australian-led team of researchers compared the complexity of the songs composed by the big blubbery mammals to those of other animals – as well as human musicians like the Beatles and Mozart. Lucinda Chambers, a bioacoustics PhD student at Australia's University of New South Wales, told AFP that people are often surprised when they hear the 'otherworldly' hoots and trills sung by leopard seals. 'It kind of sounds like sound effects from an '80s sci-fi movie,' said the lead author of a new study in the journal Scientific Reports. During the spring breeding season, male leopard seals dive underwater and perform their songs for two minutes before returning to the surface for air. They then repeat this performance for up to 13 hours a day, according to the study. The researchers determined that all leopard seals share the same set of five 'notes' that are impossible to distinguish between individuals. However, each seal arranges these notes in a unique way to compose their own personal song. 'We theorise that they're using that structure as a way to broadcast their individual identity, kind of like shouting their name out into the void,' Chambers said. The researchers believe the males use these songs to woo potential female mates – and ward off rivals. 'Songbirds of the ocean' The team studied recordings of 26 seals captured by study co-author Tracey Rogers off the coast of Eastern Antarctica throughout the 1990s. 'They're like the songbirds of the Southern Ocean,' Rogers, also from the University of New South Wales, said in a statement. 'During the breeding season, if you drop a hydrophone into the water anywhere in the region, you'll hear them singing.' The team analysed how random the seals' sequences of notes were, finding that their songs were less predictable than the calls of humpback whales or the whistles of dolphins. But they were still more predictable than the more complex music of the Beatles or Mozart. 'They fall into the ballpark of human nursery rhymes,' Chambers said. This made sense, because the songs need to be simple enough so that each seal can remember their composition to perform it every day, she explained. She compared it to how 'nursery rhymes have to be predictable enough that a child can memorise them'. But each seal song also needs to be unpredictable enough to stand out from those of the other males. Leopard seals, which are the apex predator in Antarctic waters, swim alone and cover vast distances. They likely evolved their particular kind of song so that their message travels long distances, the researchers theorise. Varying pitch or frequency might not travel as far in their environment, Chambers said. Female seals also sing sometimes, though the scientists do not know why. Chambers suggested it could be to teach their pups how to sing – though exactly how this talent is passed down is also a mystery. She added, however, that this behaviour has never been observed in the wild. 'The females could also simply be communicating with each other,' she said.

What lies beneath the ice? Antarctic mystery deepens with 'strange radio pulses'

Antarctica's vast ice sheet conceals a world of mysteries, from ancient river-carved landscapes to unexplained radio pulses. — Cover Images/Zuma Press/dpa Mountains, sub-glacial lakes, hidden valleys, even remnants of lost civilisations: what lies under Antarctica's vast 2,000-metre thick ice sheet has long been a mystery akin to the depths of the ocean or the dark side of the moon. As big as the United States and India combined, much of the frozen continent is off-limits to the handful of hardy visitors permitted each year, adding to the mystery. The sense of enigma has been heightened by the revelation that 'strange radio pulses' detected in the ice defy explanation after almost a decade of trying to figure them out. First picked up in 2016 by instrument-laden balloons flown by Nasa's Antarctic Impulsive Transient Antenna (Anita) team, the inexplicable 'anomalies' appear to be a 'form of radio waves,' according to researchers from Penn State University (PSU). But what makes the pulses anomalous is that they 'appeared to be coming from below the horizon' – an orientation that 'cannot be explained by the current understanding of particle physics,' the researchers confirmed. 'The radio waves that we detected nearly a decade ago were at really steep angles, like 30 degrees below the surface of the ice,' said PSU's Stephanie Wissel, who was part of the Nasa Anita team. In other words, the pulses should have been absorbed by rock – thousands of kilometres of it going by the angle of the pulses – long before the balloons could detect them. 'It's an interesting problem because we still don't actually have an explanation for what those anomalies are,' Wissel said. Funded by the US Department of Energy and the US National Science Foundation, the PSU researchers were part of a team made up of dozens of scientists that worked at the world's biggest cosmic ray detector – the Pierre Auger Observatory on the western Argentine plain – to try solve the riddle. The team's attempt to decode the mystery featured in the journal Physical Review Letters in late March and was publicised in a statement released by PSU in mid-June. In mid-March, a multinational team of scientists including representatives of the British Antarctic Survey (BAS) published what they described as 'the most detailed map yet' of sub-glacial Antarctica. Showing the shape of the continent were it ice-free, the map showed a tapestry of islands, mountains and valleys and revealed the ice's thickest point to be an approximately 4,700-metre section filling an unnamed canyon. – dpa
