Role of Antarctic marine protists in trophodynamics and global change and impact of UV-B on these organisms - Rotation 0 of the Astrolabe - 2002/2003 samples

This dataset contains the locations of sampling sites for ASAC project 40 on rotation 0 of the French polar supply ship L'Astrolabe in the 2002/2003 season. Samples were collected between October and November of 2002. It also contains the final dataset which has 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:VoyageTube LabelDate (UTC)Time (UTC)Time (Local)Nominal Depth (m)LatitudeLongitudeSea TemperatureIce (Presence or Absence - 1 or 0 respectively)Coccolithophorid sample (yes or no)Plankton Net SampleChlorophyll a (micro grams per litre)Pigments

这个数据集包含2002/2003季法国极地补给船“星盘号”（L'Astrolabe）第0航次ASAC项目40的采样点位置。样本采集于2002年10月至11月期间。它还包含最终数据集，其中涵盖叶绿素、类胡萝卜素、颗石藻（coccolithophorids）以及物种鉴定与计数的相关信息。

项目公开摘要：
本项目旨在明确南极水域中单细胞植物、动物、细菌及病毒的作用。我们量化了它们作为其他生物食物来源的关键角色，以及其通过吸收二氧化碳（CO₂）和产生二甲基硫（DMS）对减缓全球气候变化的潜在影响，并探究了它们对气候变化效应的响应。
