The stable oxygen isotope analysis of peat core from Mohos peat bog is an important part of our palaeoclimatic studies.

The peat bog is located in the volcanic Ciomadul Mountain, Romania (46 ° 8’3.60 “N; 25 ° 54’19.43” K; 1050 masl). A 10.5 m drilling available for paleoclimatic studies. From preliminary investigations we know it covers a period from 11.500 years and it can be used as a climate archive. The isotope studies are based on the temperature reconstruction of the oxygen isotope ratio of alpha-cellulose prepared from peat moss. Due to the validation of the climate models with recent data, it is necessary to take fresh samples of the peat and precipitation. In September 2016, we installed a precipitation collector and we took freshly grown peat moss.
