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".

采样点位于西北黑海大陆架斜坡，精确坐标为北纬43.925917°、东经30.758911°，水深658米，所处为缺氧/硫化缺氧（euxinic）环境，该环境于表层下约150米深度处开始形成。
本研究发布本次案例研究的最终中期数据成果，该数据为构建过去5500年高分辨率沉积模型奠定了基础并提供了有效支撑。本次AMS（加速器质谱，Accelerator Mass Spectrometry）放射性碳定年的测试材料为块状有机质。
我们提供了25组针对每层2厘米厚有机质采样层的放射性碳定年数据。放射性碳原始数据文件（.dat格式）可使用BATS 4.06数据处理软件进行解析。最终输出文件用于网页浏览器可视化展示（.xhtml格式）。针对2020年10月1日、2021年3月19日及2021年3月24日开展的3次AMS测量，每组测量均对应3个数据文件。
为识别沉积物中有机质的储层来源，我们测定了12个样品的δ¹³C值与C/N原子比值，相关数据详见文件"Experimental_data_13C.xlxs"与"Experimental_data_C-N.xlxs"；δ¹³C测量的原始数据可在"raw_exp_data_13C.pdf"中获取。
XRF（X射线荧光光谱，X-ray Fluorescence）数据文件可与布鲁克（Bruker）仪器工具1.6.0.110软件兼容（.pdz格式），相关结果同时整理于Microsoft Excel文件中。
我们还附上了全部25个采样深度的总有机碳（TOC，Total Organic Carbon）测定数据（文件"Experimental_data_TOC.xlxs"），以及见于"Experimental_data_210Pb-137Cs.xlxs"中的²¹⁰Pb与¹³⁷Cs放射性活度水平。
