Role of Antarctic marine protists in trophodynamics and global change and impact of UV-B on these organisms - Rotation 4 of the Astrolabe - 2009/2010 samples

This dataset contains locations of sampling sites for ASAC project 40 on rotation 4 of the French polar supply ship L'Astrolabe in the 2009/2010 season. Samples were collected between February and March of 2010. It also contains information on chlorophyll, carotenoids, coccolithophorids and species identification and counts.

Public Summary from the project:
...
This program aims to determine the role of single celled plants, animals, bacteria and viruses in Antarctic waters. We quantify their vital role as food for other organisms, their potential influence in moderating global climate change through absorption of CO2 and production of DMS, and determine their response to effect of climate change.

本数据集涵盖2009/2010航季法国极地补给船“阿斯托勒号（L'Astrolabe）”执行第4次轮换任务期间，ASAC项目40（ASAC Project 40）的采样点位坐标信息。样本采集工作于2010年2月至3月间完成。数据集同时包含叶绿素、类胡萝卜素、颗石藻（coccolithophorids）相关数据，以及物种鉴定与种群计数信息。

项目公开摘要：
本项目旨在阐明单细胞植物、动物、细菌与病毒在南极海域的生态功能：量化其作为其他生物饵料的核心作用，评估其通过吸收CO₂与生成二甲基硫（DMS）缓解全球气候变化的潜在影响，并明确其对气候变化的响应机制。
