X-ray fluorescence measurements (XRF) on sediment core RD04 (island of Sylt), BT02 and BT03 (Bay of Tümlau, south-eastern North Sea)

The dataset comprises X-ray fluorescence measurements using an ITRAX XRF core scanner with a high-power Chromium-XRF source (down-core resolution 1 mm). The sediment cores were recovered from a natural back-barrier salt marsh (island of Sylt) and a former managed salt marsh (Bay of Tümlau) in the south eastern North Sea. XRF-core scanning data were used as high-resolution proxy for grain size.本数据集包含采用ITRAX XRF岩心扫描仪搭载高功率铬靶X射线荧光（X-ray fluorescence, XRF）源获取的X射线荧光测量数据，其岩心轴向分辨率为1毫米。所用沉积物岩心采自北海南部海域的两处地点：一处为叙尔特岛的天然障后盐沼，另一处为图姆劳湾的昔日经人工管护盐沼。XRF岩心扫描数据被用作粒度分析的高分辨率替代指标。
