Role of Antarctic marine protists in trophodynamics and global change and impact of UV-B on these organisms - Rotation 0 of the Astrolabe - 2008/2009 samples

This dataset contains locations of sampling sites for ASAC project 40 on rotation 0 of the French polar supply ship L'Astrolabe in the 2008/2009 season. Samples were collected between October and November of 2008. 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.

本数据集收录了2008/2009年度极地科考季中，法国极地补给船L'Astrolabe（星盘号）第0轮换航次下ASAC项目40的采样站位信息。所有样品采集于2008年10月至11月期间。数据集同时包含叶绿素、类胡萝卜素、颗石藻（coccolithophorids）相关数据，以及物种鉴定结果与个体计数信息。

项目公众摘要：
本项目旨在探究南极水域中单细胞植物、动物、细菌与病毒的生态功能：量化其作为其他生物饵料的关键作用，分析其通过吸收二氧化碳与生成二甲基硫（DMS）调节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。
