中国第8次南极科学考察(1991-1992)中山站近岸冰藻和浮游植物种名分析数据

本数据样品采集于1992年4-12月南极中山站近岸，用PICO冰钻钻取冰芯，在实验室内从表到底10cm分层，样品在室温（约10℃）下避光自然融化，水样用2.5L Kemmerer采水器分层采集。融化样和水样经过滤浓缩后用戊二醛固定（最终浓度为1.5%）， 低温（4℃）避光保存回国，用HITACHI S-520型电镜和Zeiss AXIOSKOP 50 型光学显微镜进行藻种鉴定。共鉴定藻种70种，其中硅藻65种。 采集相关数据的主要目的是了解中山站近岸微型藻类的群落结构、垂直分布和季节变化。Dataset samples were collected from the nearshore area of Zhongshan Station, Antarctica, between April and December 1992. Ice cores were drilled using a PICO ice corer, then sectioned at 10 cm intervals from the surface to the bottom in the laboratory. The core samples were naturally melted in the dark at room temperature (approximately 10℃), while water samples were collected in stratified layers using a 2.5 L Kemmerer water sampler. Both the melted core samples and collected water samples were filtered and concentrated, fixed with glutaraldehyde at a final concentration of 1.5%, stored under dark, low-temperature (4℃) conditions, and transported back to the home country for further analysis. Algal species identification was conducted using a HITACHI S-520 scanning electron microscope and a Zeiss AXIOSKOP 50 optical microscope. A total of 70 algal species were identified, including 65 diatom species. The primary objective of this dataset acquisition was to investigate the community structure, vertical distribution, and seasonal variations of microalgae in the nearshore area of Zhongshan Station.
