In the past few weeks, we have been publishing various reports from the 2012 General Assembly, courtesy of our guest bloggers. Today, we bring you yet another report, in video format this time, produced by the lovely Sue Voice who worked at the press office in Vienna. The video features Otago University’s Christian Ohneiser talking about his PhD project. Christian tells Sue how drill cores, retrieved from remote dry valleys of Antarctica, can help us understand the past climate of the Southern Ocean.
