Role of Antarctic marine protists in trophodynamics and global change and impact of UV-B on these organisms - Rotation 4 of the Astrolabe - 2010/2011 samples

Locations of sampling sites for ASAC project 40 on rotation 4 of the French polar supply ship L'Astrolabe in the 2010/2011 season. Samples were collected between February and March of 2011.The final dataset will contain 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)

ASAC项目40第4航次在2010/2011航季，依托法国极地补给船L'Astrolabe的采样点位分布情况。样品采集于2011年2月至3月期间。最终数据集将包含叶绿素、类胡萝卜素、颗石藻（coccolithophorids）相关信息，以及物种鉴定与计数数据。项目公共摘要：本项目旨在探明南极海域中单细胞植物、动物、细菌与病毒的生态作用：量化它们作为其他生物饵料的关键作用，及其通过吸收二氧化碳、生成二甲基硫（DMS）在缓解全球气候变化中发挥的潜在影响，并明确它们对气候变化影响的响应机制。如需获取更多相关信息，请查阅ASAC项目40（ASAC_40）的其他元数据记录。本数据集包含以下字段：管签、协调世界时（UTC）日期、协调世界时（UTC）时间、纬度、经度、海水温度、海冰（存在/缺失）、颗石藻采样标记（是/否）、浮游生物网样品、叶绿素a含量（微克/升）
