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.For more information, see the other metadata records related to ASAC project 40 (ASAC_40).The fields in this dataset are:Tube LabelDate (UTC)Time (UTC)LatitudeLongitudeSea TemperatureIce (Presence or Absence)Coccolithophorid sample (yes or no)Plankton Net SampleChlorophyll a (micro grams per litre)

本数据集涵盖2009/2010航季期间，法国极地补给船“阿斯托拉贝号”（L'Astrolabe）第4轮次任务中，ASAC项目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。
本数据集还包含叶绿素、类胡萝卜素、颗石藻（coccolithophorids）以及物种鉴定与计数相关信息。
本项目公开摘要如下：
本项目旨在探究南极海域中单细胞植物、动物、细菌与病毒的生态功能。我们将量化其作为其他生物饵料的关键生态作用，以及它们通过吸收二氧化碳（CO₂）、产生二甲基硫（DMS）来缓解全球气候变化的潜在影响，并明确其对气候变化影响的响应机制。
