Quantitative radiolarian data collected from the 2017 RV Investigator voyage, IN2017_V01

Radiolarian data from IN2017_V01These data were generated by Kelly-Anne Lawler (corresponding author, [e-mail]) with taxonomic assistance from Dr Giuseppe Cortese. These data are based on samples collected during voyage IN2017_V01 of the RV Investigator, co-chief scientists, Leanne Armand and Phil O’Brien. The IN2017-V01 post-cruise report is available through open access via the e-document portal through the ANU library. https://openresearch-repository.anu.edu.au/handle/1885/142525The preferred citation is: L.K.

Samples were air dried at ambient temperature (~21 degrees C), and their processing in preparation for microscopy was based on the method of Cortese and Prebble (2015). Cover slips were adhered to the slides using Canada Balsam and slides were observed using Olympus BH-2 inverted light microscope at up to 400x magnification. Slides were first counted to determine absolute radiolarian abundance (ARA) and, for samples where ARA was high enough, more than 400 individuals were identified per sample to species/subspecies or genus level. Taxonomic nomenclature used while preparing the dataset was per Lazarus et al. (2015) with additional clarification sought from the World Register of Marine Species (WoRMS Editorial Board, 2018) and radiolaria.org (radiolaria.org, 2018).

IN2017_V01航次放射虫数据集
本数据集由Kelly-Anne Lawler（通讯作者，邮箱：[e-mail]）生成，Giuseppe Cortese博士提供分类学协助。本数据集基于「调查者号」科考船（RV Investigator）IN2017_V01航次采集的沉积物岩芯样品，该航次的联合首席科学家为Leanne Armand与Phil O’Brien。

IN2017_V01航次的航后报告可通过澳大利亚国立大学（ANU）图书馆电子文档门户开放获取，链接：https://openresearch-repository.anu.edu.au/handle/1885/142525

放射虫分析样品在岩芯回收后即刻于科考船上采集。样品于室温（约21℃）下自然风干，显微镜观测前的样品处理流程参照Cortese与Prebble（2015）提出的方法。采用加拿大树胶（Canada Balsam）将盖玻片封固于载玻片上，使用奥林巴斯BH-2型倒置光学显微镜（Olympus BH-2）以最高400倍放大倍率进行观测。首先对载玻片进行计数以确定放射虫绝对丰度（Absolute Radiolarian Abundance, ARA）；对于ARA足够高的样品，每个样品统计鉴定超过400个个体，鉴定至种/亚种或属水平。

本数据集编制过程中采用的分类学命名规则参照Lazarus等（2015）的标准，并参考了《世界海洋物种名录》（World Register of Marine Species, WoRMS，2018）及radiolaria.org（2018）进行补充校准。

本数据集的采集目的为提供古海洋学相关数据。
