For all details see the full metadata description at "https://doi.pangaea.de/10.1594/PANGAEA.906582"! ** Sediment properties of a 223-m-long drill core from the Ejina basin, NW China, for reconstructing the palaeoenvironmental history of a part of the Gobi Desert. The sediment study is part of the Q-TiP project (Quaternary Tipping Points of Lake Systems in the Arid Zone of Central Asia) in the frame of the CAME II program (BMBF funded).
