Role of Antarctic marine protists in trophodynamics and global change and impact of UV-B on these organisms - Rotation 0 of the Astrolabe - 2009/2010 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 2009/2010 season. Samples were collected between October and November of 2009. 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)

本数据集收录了2009/2010航季法国极地补给船“星盘号”（L'Astrolabe）执行ASAC项目40第0航次的采样点位信息。样本采集于2009年10月至11月期间。本数据集还涵盖叶绿素、类胡萝卜素、颗石藻（coccolithophorids）的相关数据，以及物种鉴定与物种计数结果。

项目公开摘要显示：本项目旨在探明南极海域中单细胞植物、动物、细菌与病毒的生态功能：量化其作为其他生物饵料的核心作用，以及它们通过吸收二氧化碳（CO₂）、生成二甲基硫（DMS）以缓解全球气候变化的潜在影响，并揭示其对气候变化效应的响应机制。
