Dissolved organic matter in Central Arctic Ocean during the PS94 cruise

This dataset consists of data from 531 water samples collected during the PS94 cruise in August-October 2015. Water samples were collected over the water column at 48 stations. Those stations covered different hydrographic regimes, with stations under influence of the Atlantic inflow into the Arctic Ocean in the Nansen basin, as well as the influence of riverine through the Transpolar Drift. In this dataset we present results on dissolved organic matter, specifically the dissolved organic carbon (DOC) concentrations, colored dissolved organic matter (CDOM) absorption coefficient at 350 nm (a350) and the spectral slope of the CDOM absorption between 275-295 nm (S275_295). We additionally present the correspondent salinity data for each sample.

本数据集收录了2015年8月至10月期间，在PS94航次中采集的531份水样数据。这些水样在48个站点上对水柱进行了采集，覆盖了多种水文区域，包括受北大西洋流入北冰洋的Nansen海盆影响的站点，以及通过穿越极地漂流的河流影响下的站点。在该数据集中，我们展示了关于溶解有机物的研究结果，特别是溶解有机碳（DOC）浓度、350纳米处有色溶解有机物（CDOM）的吸收系数（a350）以及275至295纳米范围内CDOM吸收的光谱斜率（S275_295）。此外，我们还提供了每个样本的对应盐度数据。
