Annual Meeting invited speakers
Martin Jakobsson
After completing his PhD in Stockholm and his first postdoc at the University of New Hampshire, Martin returned to Stockholm in 2004, where he is now Professor of Marine Geology and Geophysics and head of the Department of Geosciences. He is member and 1st Vice President the Royal Swedish Academy of Sciences. Martin spent more than one year onboard ocean research vessels and acted been Co-Chief Scientist on eight international ocean expeditions. His research focusses on the Arctic Ocean glacial history, the West Antarctic Ice Sheet, submarine glacial landforms and geophysical seafloor mapping using acoustic methods. In his talk, he will discuss the progress over the last decades concerning our knowledge of the Northern Hemisphere ice-sheets prior to the Last Glacial Maximum (LGM). Since traces of the older glaciations are scarce, erased during subsequent ice advances, the uncertainties of pre-LGM ice sheets’ extents and behaviours remain high. However, a recent synthesis of numerical modelling results and other information reveals interesting patterns throughout the Quaternary. An intriguing component of the Arctic Ocean glacial history is the existence of km-thick large floating ice shelves, which during, at least one previous glacial period, i.e. Marine Isotope Stage 6 (ca 140 ka), may have extended virtually across the entire Arctic Ocean.
