Epic Antarctic voyage maps seafloor to predict ocean rise as glacier the size of California melts – The Guardian

The concerning trend was confirmed by Australian scientists in December, who reported that warming ocean temperatures were causing the rapid melt of the end of the Totten glacier, which is holding back enough ice to create a global sea rise of between 3.5 meters and six meters. The 51-day mission is one of the longest ever voyages by Australian scientists to Antarctica and will involve mapping the unexplored Sabrina Coast seafloor and take samples of piles of glacial sediment left behind by the retreating ice sheet. The worst scenario was that the ice tongue of the glacier could disappear.

Key Takeaways:

  • An ice shelf in East Antartica has been steadily melting for the past several months.
  • A team of scientists will board research ship to map the seafloor in the ice shelf’s area, hoping to predicting melting patterns for the future.
  • The expedition will be tough, requiring the scientists to bring specifically tested eqiupment with a few of their own personal luxuries.
