Submarine groundwater discharge and gas hydrate dissociation fuel organic matter formation in Arctic fjord sediments

Data on sedimentary organic carbon, total nitrogen and their stable isotopes from sediments collected in Svalbard fjords. Furthermore, porewater chloride concentration and water isotopes were measured. The excel file contains three sheets: · Metadata – Description of all columns present in the other 2 sheets · Core_information – Sampling location and sampling gear for every individual core · Measured_variables – all measurements of the individual parameters The research leading to these results has received funding from the Norwegian Financial Mechanism 2014–2021 project no. 2019/34/H/ST10/00645 and within the statutory activities of the Institute of Oceanology Polish Academy of Science. W.-L.H. acknowledges the support from the Swedish Research Council (VR) under the project "Cryosphere-driven submarine groundwater in the Arctic" (Project No: 2021-04962).本数据集涵盖斯瓦尔巴群岛峡湾沉积物的沉积有机碳、总氮及其稳定同位素数据，同时包含孔隙水氯离子浓度与水体同位素的测定结果。该Excel文件包含三个工作表： · 元数据（Metadata）：其余两个工作表中所有列的详细说明 · 岩芯信息（Core_information）：每一根独立岩芯的采样位置与采样设备 · 测定变量（Measured_variables）：各参数的全部实测结果 本研究的开展获得了2014–2021年挪威金融机制项目（项目编号：2019/34/H/ST10/00645）以及波兰科学院海洋研究所法定科研活动经费的支持。W.-L.H. 感谢瑞典研究理事会（VR）为项目“北极冰冻圈驱动的海底地下水”（项目编号：2021-04962）提供的资助。
