New cause of melting Antarctic ice shelves

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 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.
