Geochemistry in the Romanian shelf waters - July 2023 (PN 23 30 01 03 - National Project)

Dataset contains geochemistry data from the Romanian shelf. Data were collected on board R/V Mare Nigrum, during a cruise conducted in July 2023, within the national project "Improving the monitoring program for the Romanian Black Sea self in order to increase the capacity to assess and predict the impact of multistressors on marine ecosystem services" PN 23 30 01 03 National Project. Twenty-six stations distributed along 3 main transects (Sf. Gheorghe-SE, Portita-SE, and Constanta-SE) were performed for geochemical investigations by the GeoEcoMar team. Sediment samples were collected using Van Veen grab sampler and Multicorer MARK II-400, and analyzed for major and minor components as well as trace elements (by X-ray fluorescence) in the GeoEcoMar lab.本数据集收录罗马尼亚黑海陆架的地球化学数据。相关数据由“马雷·尼格鲁姆号”科考船（R/V Mare Nigrum）于2023年7月执行的航次中采集获取，该航次隶属于国家项目“优化罗马尼亚黑海陆架监测方案，提升多胁迫因子对海洋生态系统服务影响的评估与预测能力”（项目编号：PN 23 30 01 03）。GeoEcoMar团队沿3条主要断面（圣格奥尔基-东南向、波尔蒂察-东南向、康斯坦察-东南向）布设26个采样站位，用于开展地球化学调查。研究人员采用范·维恩采泥器（Van Veen grab sampler）与多管采泥器MARK II-400（Multicorer MARK II-400）采集沉积物样品，并在GeoEcoMar实验室通过X射线荧光光谱法（X-ray fluorescence）对样品的常量组分、微量组分及痕量元素开展分析测试。
