Sediment elemental composition (XRF) of sediment core GeoB19920-1, 30 kV run@en

XRF Core Scanner data of sediment core GeoB19920-4 from Baffin BAy were collected every two centimetres downcore over an active area of 15 mm² with a downcore slit size of 10 mm using generator settings of 30 kV directly at the split core surface of the archive half with XRF Core Scanner II (AVAATECH Serial No. 2) at MARUM, Bremen.巴芬湾（Baffin Bay）沉积物岩芯GeoB19920-4的XRF岩芯扫描仪（XRF Core Scanner）测量数据，由不来梅MARUM的XRF岩芯扫描仪II型（AVAATECH，序列号2）采集得到。采集过程中，仪器直接置于存档半岩芯的剖开面上，采用30千伏的发生器工作参数，岩芯扫描狭缝尺寸为10毫米，有效测量区域面积为15平方毫米，沿岩芯轴向每2厘米采集一组数据。
