Nella Dan: SIBEX II Cruise Phytoplankton Data

This dataset contains results from the Second International BIOMASS Experiment II (SIBEX II) cruise of the Nella Dan, taken in January 1985. This cruise was the fourth cruise in a series of six. Phytoplankton samples were taken off Antarctica in the Australian sector (Mawson to Davis region) and Prydz Bay in January 1985. Taxonomic identity, distribution and abundance data were obtained, together with an extensive range of pigment analysis, using high performance liquid chromatography (HPLC). Over 60 pigments were analysed (only the major ones are listed here). The major phytoplankton investigated were diatoms, dinoflagellates and flagellates. This dataset is a subset of the full cruise.An excel spreadsheet containing the full pigment analysis obtained from the cruise is available for download from the URL given below. The spreadsheet is a digital version of the data presented in ANARE Research Notes 58, which was a report written based on this dataset. There are three worksheets to the spreadsheet:1) Abbrev. - details the abbreviations used in worksheets 2 and 3.2) Table 3 - Table 3 data entered from ANARE Research Notes 58.3) Transposed Table 3 - The same data as worksheet 2, but arranged differently.A pdf copy of ANARE Research Notes 58 is also available for download at the URL given below. A paper written in 2006 about pigments in microalgae, which provides some up-to-date explanations about pigmentation, is also available for download, but owing to copyright restrictions, is only available for download by Australian Antarctic Division personnel.The fields in this dataset are:DateTime (GMT)LatitudeLongitudeDepth (metres)Pigment concentration (nanograms per litre)chlorophyllide achlorophyll cmethyl chlorophyllide aphaeophorbide aperidinin19'-butanoyloxyfucoxanthinfucoxanthin19'-hexanoyloxyfucoxanthinNeoxanthinPrasinoxanthinViolaxanthinDiadinoxanthinAlloxanthindiatoxanthinZeaxanthinCanthaxanthinUnknownChlorophyll bChlorophyll a allomerChlorophyll aChlorophyll a epimerPhaeophytin a derivativePhaeophytin bPhaeophytin aChlorophyll a total% DegradationPigment totalThis work was completed as part of ASAC project 40 (ASAC_40).

本数据集源自1985年1月“内拉丹号（Nella Dan）”执行的第二次国际生物量实验II（SIBEX II）航次的观测结果。该航次是整组6个航次序列中的第4个航次。1985年1月，科研人员在澳大利亚管辖的南极海域（莫森站至戴维斯站区域）以及普里兹湾采集了浮游植物样本。本次研究获取了浮游植物的分类鉴定信息、分布情况及丰度数据，同时通过高效液相色谱（High Performance Liquid Chromatography，HPLC）开展了大范围的色素分析，共检测超过60种色素（本数据集仅列出主要色素种类）。本次研究涉及的主要浮游植物类群包括硅藻、甲藻与鞭毛藻。

本数据集为该航次完整观测数据的子集。可通过下述链接下载包含该航次完整色素分析数据的Excel电子表格：该电子表格为《ANARE研究通讯第58期（ANARE Research Notes 58）》刊载数据的数字化版本，该报告正是基于本数据集撰写而成。该电子表格包含3个工作表：1) 缩写说明（Abbrev.）：列明工作表2与工作表3中所用的缩写；2) 表3（Table 3）：录入自《ANARE研究通讯第58期》的表3数据；3) 转置表3（Transposed Table 3）：与工作表2数据一致，但排版格式不同。

《ANARE研究通讯第58期（ANARE Research Notes 58）》的PDF版本也可通过下述链接下载。另有一篇2006年发表的关于微藻色素的论文，其中包含了有关色素组成的最新阐释，同样可通过链接下载，但受版权限制，仅面向澳大利亚南极局（Australian Antarctic Division）工作人员开放下载。
