Grain size and description on gravity core samples from ANT-IV/2 expedition to the Bransfield Strait

From the above and the grafical results it can be concluded that cores in the research area are locally dominated by turbiditic sequences, which can be observed by a strong increase in coarser sediment (>35 µm). These coarser intercalations are lacking in the vicinity of basaltic seamounts, probably due to a shadowing effect of the seamounts. The infill of the King George Basin might be dominated by a north eastern current. Sedimentary structures as observed in the cores are often lacking or vague due to hydrothermal effects (Suess, L, 1986).结合前述分析与图表结果可得出结论：研究区域的岩芯局部以浊积岩序列（turbiditic sequences）为主，该特征可通过粗颗粒沉积物（>35 µm）的显著富集得到印证。这类粗粒夹层在玄武质海山（basaltic seamounts）周边区域较为缺失，推测其成因与海山的遮蔽效应有关。乔治王海盆（King George Basin）的充填沉积可能主要受东北向洋流控制。岩芯中观测到的沉积构造常因热液作用（hydrothermal effects）而缺失或模糊不清（Suess, L, 1986）。
