MN183-3 detailed chronology

The sampling point is located on the slope of the NW Black Sea continental platform at the exact location described by 43.925.917 N, 30.758.911 E and at a water depth of 658 m in the anoxic/euxinic environment, which starts below the surface at around 150 m depth. Here, we publish the final data of our case study as an intermediate product, which set the base and come in handy for creating a high-resolution sedimentation model spanning the last 5500 years. The AMS radiocarbon dated material is the bulk organic matter. We present the series of 25 radiocarbon ages on the sampled layers of organic matter, each two centimeters. The radiocarbon raw data files (.dat files) work with BATS 4.06 data reduction software. The final output file is written for web browser visualisation (.xhtml files). There are three data files for each of the AMS measurements performed on 1.10.2020, 19.03.2021 and 24.03.2021. For the identification of the reservoir sources of the organic matter in sediments we've resorted to measure the δ13C (#12 samples) and C/N atomic ratio (files: "Experimental_data_13C.xlxs" and "Experimental_data_C-N.xlxs"; the raw data for the 13C measurements is found in "raw_exp_data_13C.pdf"). The XRF files are compatible with Bruker Instrument Tools 1.6.0.110 software (.pdz files). These results are also transcripted in MS Excel files. We attach also the TOC measurement taken on all the 25 depths (Experimental_data_TOC.xlxs") and the radioactivity levels for 210Pb and 137Cs found in "Experimental_data_210Pb-137Cs.xlxs".
