![]() Instead, the iceberg has taken a meandering trajectory as its movement is dictated by ocean currents and winds. The chart plotted by BAS showed that A23a's journey is not a linear affair. "This is the first step towards scientists being able to track the complete life cycle of most icebergs across Antarctica from satellite data!" a post said. In a follow-up post, BAS also added that its researchers have developed a new AI tool to detect icebergs in the Southern Ocean. The 18-second clip sparked wonder online and has been viewed almost 47,000 times. The post accompanying the footage said "The largest iceberg, A23a, is on the move! Here's its journey out of the Weddell Sea after being grounded on the sea floor after calving in August 1986." Here's its journey out of the Weddell Sea after being grounded on the sea floor after calving in August 1986.Ĭopernicus Sentinel-1 imagery, Google Earth Engine □ /KseKTD1Wrg- British Antarctic Survey □ November 24, 2023 □ Double-whammy iceberg news this morning:ġ️⃣ The largest iceberg, A23a, is on the move! It can be viewed in the attached video above, or in the BAS post here: ![]() The iceberg's path so far was shared on X (the social media site previously known as Twitter) on Friday. Scientists from the British Antarctic Survey (BAS) released striking satellite imagery on Friday, tracking A23a's path as it barrels forward, toward the outer edges of the Weddell Sea. "It was grounded since 1986 but eventually it was going to decrease sufficiently to lose grip and start moving. "I asked a couple of colleagues about this, wondering if there was any possible change in shelf water temperatures that might have provoked it, but the consensus is the time had just come," Andrew Fleming, a remote sensing expert from the British Antarctic Survey, told the BBC last week. However, in the case of A23a, experts don't believe that climate change is responsible for its sudden lurch to life. Pictured: An iceberg photographed near Ittoqqortoormiit, Greenland, on August 12, 2023. Scientists are monitoring the progress of a massive iceberg drifting out away from Antarctica. But there have been concerns in recent years that rising sea temperatures caused by climate change are contributing to a greater amount of ice loss. Icebergs can benefit the ecosystems and food chains surrounding them as they release minerals into the sea as they melt. Chunks of ice do break away, or "calve," occasionally in a natural process of iceberg formation. Although it has been drifting for years, a sudden burst of activity and increased rate of movement has seen renewed interest in A23a over recent days.Īntarctica is the coldest place on Earth, with temperatures sometimes plunging to a frigid -135.8 F. In 2020, it detached from sea floor and began to drift in a journey that is being monitored by scientists and iceberg enthusiasts from around the world. However, it almost immediately became stuck to the ocean floor of the Weddell Sea and remained 'beached' there until a few years ago. The giant icy mass, with the snappy moniker of "A23a," first broke away from Antarctica in 1986. Coast Guard archive, he said.A massive iceberg, five times bigger than New York City, is on the move and about to leave the Antarctic Peninsula-bound for the open waters of the southern Atlantic Ocean. The other, taken by Captain William George Squares de Carteret of the SS Minia, is from a U.S. ![]() Moreover, it's likely that the fatal iceberg came from one of Greenland's southern glaciers, Bigg discovered.ĭuring his research, Bigg learned about the two iceberg photos. Common lore suggested that the Atlantic was littered with an unusually high number of icebergs during the spring of 1912, but by studying old Coast Guard records, the researchers found that 1912 was an average year for dangerous floating ice. In 2014, Bigg co-wrote a study about the number of icebergs floating in the Atlantic Ocean in 1912. "There are two photos of icebergs from the area on the day following the collision, both of which purport to be the Titanic iceberg," said Grant Bigg, an environmental scientist at the University of Sheffield in England. However, this isn't the only photo that could show the Titanic's iceberg. The photo hung in the firm's office for nearly 90 years, from 1913 until 2002, when the firm closed. ![]() Hamburg America Lines originally gave the photo to its attorneys, Burlingham, Montgomery & Beecher, when it learned that the firm would be defending the Titanic's company, White Star Line, in court. ![]()
