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

Radiolarian data from IN2017_V01

These 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.

Samples for radiolarian analysis were collected on board immediately after core recovery. 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]）构建，Giuseppe Cortese博士提供分类学协助。本数据集的样品采集自“探索者号”（RV Investigator）IN2017_V01航次，本航次联合首席科学家为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（Australian National University，ANU）图书馆的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船上采集。样品于室温（约21℃）下自然风干，镜检前的样品处理流程参照Cortese与Prebble（2015）的方法。使用加拿大树胶（Canada Balsam）将盖玻片封固于载玻片上，采用奥林巴斯BH-2倒置光学显微镜（Olympus BH-2 inverted light microscope）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，每个样品需鉴定超过400个个体至种/亚种或属水平。本数据集构建时采用的分类学命名规范参照Lazarus等（2015）的成果，并参考了《世界海洋物种登记册》（WoRMS Editorial Board, 2018）及放射虫专业网站radiolaria.org（2018）进行补充校准。
