https://safirsoft.com Ships from 1581 ports may sail to Antarctica with unwanted guests

Antarctica is more connected than we thought and needs better biological safety.

Currently, Antarctica and its surrounding waters are surprisingly free of invasive species. However, according to new research, this situation may change in the not too distant future thanks to the amazing level of connectivity to ports around the world. Ships can indiscriminately carry a range of marine life, which in turn can colonize new locations (such as the world's Antarctic), compete with native life, and destroy the ecosystem as a whole. New research traces the paths of various research vessels, cruise ships, and fishing boats that pass through the icy waters of Antarctica.

According to Arlie McCarthy, a researcher in the Department of Zoology at the University of Cambridge and in Antarctica, all these blue vessels are a danger to unwanted visitors. And visitors may have a better chance of moving than we previously thought.

"We know from other cold regions of the world, including the Arctic, that things that grow on a ship's hull aren't quite in place." They will be transferred. McCarthy told Ars. We also know that ships bound for Antarctica have things to grow. What we didn't know yet were the exact details of where those ships were headed. Falling

McCarthy's research shows that 1,581 ports around the world are connected to Antarctica, ports from which at least one ship has traveled to the area, which according to the Antarctic Treaty to determine this, he and his team looked at shipping data from Lloyd's List Intelligence, the oldest and most reliable source for marine data, port call data and raw satellite data. "It's somehow connected to Antarctica," Karti said, referring to the ports. That means countless species like crabs, crabs, and lobsters. They can be located. lighthouses from many places in this region.As global shipping increases—and as researchers and tourists continue to travel to these waters—the potential for invasive species to spread increases.There are also concerns about the movement of some species from north to Antarctica, perhaps on cruises or Research vessels Arctic species are likely to be cold tolerant and can grow better in cold Antarctica than species that enter from somewhere south of the equator.Antarctic waters are largely devoid of marine species. Gaseous - and some are gaseous as well. Weeds and insects - and the ocean is more isolated than many other oceans. This is mainly due to the neighboring Southern Ocean, which has currents around Antarctica. It is especially strong and is a barrier. “Anything that comes north via ocean currents from distant oceans can be diverted from Antarctica instead of the Southern Ocean...” McCarthy said, adding that seals and whales can pass through these currents, even if shellfish, fish and algae are often banned. .
