资源简介:
This dataset contains the locations of sampling sites for ASAC project 40 on rotation 2 of the French polar supply ship L'Astrolabe in the 2002/2003 season. Samples were collected between December and January of 2002/2003. 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)

本数据集包含ASAC项目40(ASAC project 40)在2002/2003科考季,搭乘法国极地补给船"星盘号"(L'Astrolabe)第2航次的采样点位信息。采样工作于2002年12月至2003年1月期间开展。数据集同时包含最终成果数据集,内含叶绿素、类胡萝卜素、颗石藻(coccolithophorids)的相关检测数据,以及物种鉴定与计数结果。 项目公共摘要:本项目旨在探明南极海域内单细胞植物、动物、细菌及病毒的生态功能。本项目将量化其作为其他生物饵料的核心作用,以及其通过吸收二氧化碳(CO₂)、生成二甲基硫醚(DMS)以减缓全球气候变化的潜在影响,并阐明它们对气候变化效应的响应机制。 如需获取更多信息,请查阅与ASAC项目40(ASAC_40)相关的其他元数据记录。 本数据集包含以下字段: 1. 航次管标签(VoyageTube Label) 2. 日期(UTC)(Date (UTC)) 3. 时间(UTC)(Time (UTC)) 4. 当地时间(Time (Local)) 5. 标称深度(米)(Nominal Depth (m)) 6. 纬度(Latitude) 7. 经度(Longitude) 8. 海水温度(Sea Temperature) 9. 海冰标识(Ice (Presence or Absence - 1 or 0 respectively),存在记为1,不存在记为0) 10. 颗石藻采样标记(Coccolithophorid sample,是或否) 11. 浮游生物网采样(Plankton Net Sample) 12. 叶绿素a浓度(Chlorophyll a (micro grams per litre))
