Elemental composition of sediment core 1433, Browning Bay, Windmill Islands

This data set comprises elemental data obtained from sediment samples of core 1433 (also termed PG1433). Detailed descriptions of the site and core lithology are given in Cremer et al. (2003). Geochemical analyses were performed on freeze-dried and ground material. Total organic carbon (TOC) and total inorganic carbon (TIC) were analyzed with a DIMATOC 200 analyzer (DIMATEC Corp.). Nitrogen (N wt%) and sulphur (S wt%) were measured with a Vario Mircrocube (Elementar). Inorganic elemental composition reported here was analysed with an ITRAX µXRF core scanner (Cox Analytical Systems, Sweden) with a Cr X-ray tube (settings: 30 kV, 55 mA). To convert the semi-quantitative XRF counts obtained with the ITRAX core scanner to absolute elemental concentrations reference samples with known elemental compositions were analyzed along with each batch of samples and absolute element concentrations were calculated based on linear calibration curves for elements with a Pearson correlation coefficient R² >0.65. The data set is a supplement to the manuscript \"Rapid relative sea-level fall during the mid-Holocene in the Windmill Islands, East Antarctica\" submitted for publication in the journal Quaternary Science Reviews by Small et al.

本数据集包含从岩芯1433（又称PG1433）沉积物样本中获取的元素数据。该站位及岩芯岩性的详细描述见Cremer等人（2003）的研究。地球化学分析针对冻干并研磨后的样品进行。总有机碳（TOC）和总无机碳（TIC）采用DIMATOC 200分析仪（DIMATEC公司）测定。氮（N，质量百分比）和硫（S，质量百分比）通过Vario Mircrocube仪器（Elementar公司）测量。本研究报告的无机元素组成通过配备铬（Cr）X射线管（参数：30kV，55mA）的ITRAX微X射线荧光（µXRF）岩芯扫描仪（瑞典Cox Analytical Systems公司）分析获得。为将ITRAX岩芯扫描仪获得的半定量XRF计数转换为绝对元素浓度，每批次样品均随带已知元素组成的参考样品一同分析；对于皮尔逊相关系数R²>0.65的元素，其绝对浓度基于线性校准曲线计算得出。本数据集是Small等人提交至《第四纪科学评论》（Quaternary Science Reviews）期刊、题为《东南极风车群岛中全新世期间相对海平面快速下降》的手稿的补充材料。
