The role of Antarctic marine protists in trophodynamics and global change and the impact of UV-B on these organisms - Voyage 4 2002/2003 samples (KAOS)

This dataset contains locations of sampling sites for ASAC project 40 on voyage 4 of the Aurora Australis in the 2002/2003 season (KAOS). Samples were collected between January and March of 2003. The dataset 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 include:VoyageTube LabelDate (UTC)Time (UTC)Time (Local)CTD NumberNiskin BottleNominal Depth (m)LatitudeLongitudeSea TemperatureIce (Presence or Absence)Plankton Net SamplePigments

本数据集涵盖2002/2003航季（KAOS）中“澳极光号（Aurora Australis）”第4航次的ASAC（Antarctic Science Advisory Committee，南极科学咨询委员会）40号项目的采样点位坐标。样本采集于2003年1月至3月期间。数据集同时包含叶绿素、类胡萝卜素、颗石藻相关信息，以及物种鉴定与计数数据。
本项目公开摘要如下：本项目旨在探明单细胞植物、动物、细菌与病毒在南极水域中的生态作用。我们将量化其作为其他生物饵料的核心功能，评估其通过吸收二氧化碳（CO₂）与生成二甲基硫（Dimethyl Sulfide，DMS）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。
