Sediment cores from nine sites along a profile on the Antarctic continental margin off Kapp Norvegia were analysed sedimentologicaly. The carbonate and organic carbon content, grain size distribution, composition of the coarse fraction and clay minerals were determined. d18O- and d13C-isotope ratios were also measured. The distribution of ice rafted debris was determined by a new method. Sedimentation-rates were obtained from 230Th- and 14C-analyses. […]
对诺尔韦格亚角（Kapp Norvegia）外南极大陆边缘一条剖面上的9个站位的沉积物岩芯开展了沉积学分析。测定了样品的碳酸盐与有机碳含量、粒度分布、粗粒组分组成及黏土矿物组成，同时还测定了δ¹⁸O与δ¹³C同位素比值。采用全新方法确定了冰筏碎屑（Ice Rafted Debris, IRD）的分布特征，并通过²³⁰Th与¹⁴C分析获取了沉积速率。……
