Warmer, saltier polar water could change global ocean currents

Melting ice shelves are changing the ocean's chemistry at the South Pole and the result could be a change in global currents and increased glacial melt, according to scientists who are creating maps to feed into climate change ...

Undersea topography generates hot spots of ocean mixing

Using underwater robots in the waters surrounding Antarctica, scientists at Caltech have shown that the intersection of strong currents with the slope of landmasses rising from the ocean floor makes a significant contribution ...

'Scars' left by icebergs record West Antarctic ice retreat

Thousands of marks on the Antarctic seafloor, caused by icebergs which broke free from glaciers more than ten thousand years ago, show how part of the Antarctic Ice Sheet retreated rapidly at the end of the last ice age as ...

Sentinel satellite captures birth of behemoth iceberg

Over the last few months, a chunk of Antarctica's Larsen C ice shelf has been hanging on precariously as a deep crack cut across the ice. Witnessed by the Copernicus Sentinel-1 mission, a lump of ice more than twice the size ...

Huge Antarctic ice block poised to snap off

A chunk of ice bigger than the US state of Delaware is hanging by a thread from the West Antarctic ice shelf, satellite images revealed Wednesday.
