| contents | In August 2016 the lacustrine sediment core was obtained from lake Bayan Nuur one of the northern lakes in the Great Lake Depression of Mongolia. Exact location of coring site (50.01072 N, 93.9745 E; 932 m a.s.l.) was in a water depth of 29 m at the deepest part of the lake. Corning was performed by small platform using a 60-mm gravity corer UWITEC. A 112-cm-long sediment core (BN2016-1) was studied by number of proxies including: radiocarbon dating, geochemical, pollen, diatoms and cladocera analyses. Acquired data were used for numerical analyses such as biomization, reconstruction of annual precipitation rate based on pollen data and reconstruction mean July temperature based on chironomid data, additionally was evaluated past biodiversity of the lake's microflora and microfauna using Hill numbers (Hill, 1973) based on all bioproxies data (pollen, diatoms, cladoceran, and chironomids). Six AMS radiocarbon measurements for bulk sediment samples were used for calibration and the age modeling. The average sediment accumulation rate is estimated at 0.37 mm/year. The reservoir effect calculated as 736 years was subtracted from the age-depth model. Core BN2016-1 covers the last 2885 cal. years BP. |
