  • Smooth Sailing Back to Tasmania

    Smooth Sailing Back to Tasmania

    After a surprisingly smooth crossing of the Southern Ocean, with favorable winds we arrived back in Hobart, Tasmania. The weather maps show that we just got ahead of another big storm system.

  • Taking a 4,000-Meter-Deep Profile of Antarctic Waters

    Taking a 4,000-Meter-Deep Profile of Antarctic Waters

    In addition to understanding potential pathways for “warmer” circumpolar deep water to reach the ice shelf, we are also measuring what the structure and properties of the water column are and determining if there is already warmer water on or near the continental shelf that could already interact with the glaciers of East Antarctica today.

  • Mapping the Seafloor

    Mapping the Seafloor

    One of the goals of this expedition is to investigate if water from the Southern Ocean with temperatures above the melting point of glaciers could reach the glaciers in East Antarctica, and if there are any obstacles on the seafloor of the shelf that impact the ability of such water to reach the glaciers and…

  • In the Ice

    In the Ice

    Several days ago we reached our main work areas along the margin of East Antarctica. Our expedition is relatively late in the season and the seas around Antarctica are starting to freeze.

  • Closing in on Antarctica

    Closing in on Antarctica

    We are less than a day away from our first study area on the continental shelf in front of the Dibble Glacier. As we approach Antarctica we are starting our science program with a 4500 meter deep CTD and multibeam acquisition.

  • On Our Way: Avoiding the Storm

    On Our Way: Avoiding the Storm

    We are now aboard the R/V Palmer and on our way to East Antarctica. Due to two storms in our direct way we are heading west first to go around the storms and we’ll then head south on their backside.

  • Preparing for Seven Weeks at Sea

    Preparing for Seven Weeks at Sea

    For our spring expedition, NBP1503, to the margin of East Antarctica we will live and work on board the United States icebreaker Nathaniel B. Palmer. Together we are eight scientists, 10 science support staff and 19 crew members of the ship’s crew.

  • The Oden and the Polarstern Cross Paths

    We successfully finished our scientific work in the Amundsen Sea and are now heading back to Punta Arenas, at the tip of South America. It will take eight to nine days to get there depending on the weather and winds. Just before we left the Amundsen Sea we passed the German ice-breaker ship, the Polarstern.…

  • Looking at Mud to Learn About Ice Sheets

    The bottom of the seafloor shows us where ice used to flow. To pinpoint when the ice retreated, the geologists on board take samples of mud and sand from the seafloor. Using a weighted steel barrel lowered to the seafloor they bore their way through sand and mud. A catcher at the bottom of the…
