I handed inn my second semester project last day, and things are finally starting to calm a bit down, before the exams next month. This was the second project this year, and a brief summary of them is as follows:
AG210 Quaternary history of Svalbard: I described and interpreted both the genesis and environment of a new gravel unit found within the sedimentary stratigraphy of Poolepynten on Prins Karls Forland. To do this I used both sediment description and interpretation of the mollusk fauna in which I collected shells to identify. Based on this I came to the conclution that the gravel was deposited during a high density deposit during a climate similar or warmer then today and most possible during the Eemian interglacial (130-114 000 years ago).

AG211 Marine Geology: Using mainly swath bathymetry data I identified submarine landforms within the fjord and inner-shelf area of Wijdefjorden on North-Spitsbergen. This included measuring and interpreting the significance of the different landforms. My conclusion were that a mayor ice flow were present in Wijdefjorden during the last glaciation, that it was a surging glacier, but that it could be characterized as a "fast-flowing" ice stream due to the lack of megascale glacial lineations (MSGL).
