Surface sediment grain size data set of Kongsfjorden, in the Arctic

50 surface sediment samples were taken during the fourth and fifth Chinese national Arctic research expedition in 2007 and 2008. Grain size analysis was conducted by the Laser particle size analyzers and Sieves methods. Surface sediments of Kongsfjorden are mainly composed of silt, gravel, silty sand and clay. Different kinds of marine-glacial sediment appear in different areas of Kongsfjorden due to different environments, indicating the polar-specific mode of deposition.
