Diatom abundance from CEAMARC coretop samples

This dataset contains the abundance of diatom species found in the surface sediments from cores collected as part of the CEAMARC (Collaborative East Antarctic Marine Census) mission. The cores were collected from the George V basin along the Antarctic coast. Latitude, longitude and water depth data are included for each site. Sediments were prepared following standard diatom preparation techniques (Rathburn et al 1997).本数据集包含南极东大洋联合普查（Collaborative East Antarctic Marine Census，CEAMARC）项目采集的岩芯表层沉积物中的硅藻物种丰度数据。所涉岩芯采自南极沿岸的乔治五世海盆，每个采样位点均附带纬度、经度及水深数据。沉积物样品按照标准硅藻制样技术（Rathburn et al. 1997）制备。
