Porosity in sediment cores from the central Arctic Ocean during POLARSTERN cruise ARK-XXVII/3 from August-September 2012@en

During the RV Polarstern cruise ARK-XXVII/3 to the Arctic Ocean in summer 2012, when sea ice declined to a record minimum bottom, sediment cores were collected with a TV-guided multicorer at stations in the Nansen and Amundsen basin. For porosity measurements cores were subsampled and samples were stored at 4°C until analyzes in the home laboratory.2012年夏季，极星号（RV Polarstern）科考船执行ARK-XXVII/3航次前往北冰洋，其时海冰覆盖面积降至创纪录的最低值。研究人员借助电视引导式多管取样器（TV-guided multicorer），在南森海盆（Nansen Basin）与阿蒙森海盆（Amundsen Basin）的站位采集了沉积物岩芯。为开展孔隙度测量，研究人员对岩芯进行了分样，并将样品保存于4℃环境中，直至运回本实验室完成分析。
