Existing conservation efforts insufficient to protect Antarctic ecosystems Researchers have discovered a process that can contribute to the melting of ice shelves in the Antarctic. An international team of scientists found that adjacent ice shelves play a role in causing instability in others downstream. The study, led by the University of East Anglia in the UK, also identified that a small ocean gyre - a system of circulating ocean currents - next to the Thwaites Ice Shelf can impact the amount of glacial-meltwater flowing beneath it. When that gyre is weaker, more warm water can access the areas beneath the ice shelf, causing it to melt. Meanwhile, another study says that existing conservation efforts are insufficient to protect Antarctic ecosystems, and population declines are...
