A new study has revealed that ocean tides can directly influence when large Antarctic icebergs break off from the ice shelves surrounding the continent, a process known as calving. The research marks a major step toward accurately forecasting ice loss from the Antarctic Ice Sheet and improving projections of global sea level rise.
Argentina's Coast Guard (Prefectura Naval Argentina - PNA) alerted all sailing ships this week of three icebergs near Ushuaia and advised them to avoid all unnecessary approaching these ice floes, of which only 10% is visible on the surface. The first detection was reported last Saturday by the Argentine-flagged fishing vessel Echizen Maru and the latest spotting came through on Monday at the Beagle Channel exit into the open sea.
