Biology of the Mertz Glacier Polynya - Zooplankton and CTD Data

Metadata record for data from ASAC Project 1101See the link below for public details on this project.---- Public Summary from Project ----Most of our knowledge of the Antarctic marine ecosystems comes from summer surveys. There are very few observations of this ecosystem in winter and there is a fundamental lack of knowledge of understanding of even basic questions such as 'what is there?' and 'what's it doing?'. The proposed visit to the sea ice zone in winter is a rare opportunity to conduct observations on phytoplankton, krill, birds, seals and whales, so that we can begin to understand the biological processes that go on in winter.Data for this project were intended to be collected on a 1998 winter voyage of the Aurora Australis, but a fire on board meant that the voyage had to return to port before work could be carried out.Data were then collected the following year during a 1999 winter voyage of the Aurora Australis (IDIOTS), which ran from July to September.Data attached to this metadata record, include zooplankton and CTD data collected from the Mertz Glacier region.The data have been compiled by Angela McGaffin, and can be found in the "processed" folder of the download file. Original datasets are also available in the "Original Datasets" folder.

——项目公开摘要——
我们目前对南极海洋生态系统的认知大多源自夏季科考调查。该生态系统的冬季观测数据极度稀缺，即便诸如“这里存在哪些生物？”“它们在开展何种活动？”这类基础问题，我们也尚未形成清晰认知。此次拟开展的冬季海冰区考察，为我们观测浮游植物、磷虾、海鸟、海豹与鲸类提供了宝贵契机，借此可逐步解析南极海洋生态系统的冬季生物过程。
本项目原计划于1998年搭乘“奥罗拉·奥斯特拉利斯号（Aurora Australis）”科考船的冬季航次采集数据，但船上突发火灾，致使航次在科考工作启动前被迫返航。次年，即1999年，该科考船执行了标识为IDIOTS的冬季航次，航期为7月至9月，成功完成了数据采集工作。
本元数据记录附带的数据包括从默茨冰川（Mertz Glacier）区域采集的浮游动物数据与温盐深（CTD, Conductivity, Temperature, Depth）数据。该数据集由安吉拉·麦加芬（Angela McGaffin）整理，可在下载文件的"processed"文件夹中获取；原始数据集同样存放于"Original Datasets"文件夹中。
