Absolute abundance of diatoms from CEAMARC cores

This data provides the absolute abundance of diatom valves from cores recovered from the George V coast as part of the CEAMARC (Collaborative East Antarctic Marine Census) mission of 2007-2008. Data are presented as valves/gram dry weight of sediment. All samples analyzed were core top samples, however no age constraints have been established. Chaetoceros resting spores were included in the absolute abundance calculations. Slides were prepared following Rathburn et al 1997.

本数据集提供了2007-2008年CEAMARC（东南极海洋联合普查，Collaborative East Antarctic Marine Census）科考任务中从乔治五世海岸（George V coast）获取的岩芯内硅藻壳的绝对丰度数据。数据以“每克沉积物干重对应的硅藻壳数”形式给出。所有分析样品均为岩芯表层样品，但尚未建立年代约束条件。角毛藻（Chaetoceros）休眠孢子已被纳入绝对丰度计算范围。玻片制备遵循Rathburn等1997年的实验方法。
