资源简介:
This dataset contains locations of sampling sites for ASAC project 40 on rotation 4 of the French polar supply ship L'Astrolabe in the 2007/2008 season. Samples were collected between February and March of 2008. 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)Local time (dec hrs)actual solar local time (decimal hours) calc from longitudeDOES NOT EQUAL TIME ZONELongitude decimal degrees/degrees, minutesLatitude decimal degrees/degrees, minutesSea Temperature degrees CelsiusIce present/absentLugol's bottle # - microscope sample number for phytoplankton ID (Our use only)HPLC Volume remaining - volume filtered for HPLC pigment analysis (Our use only)Volume filtered for HPLCVolume remaining for CoccolithsCoccolith tray No.(Our use only)Coccolith tray position numberNet Sample TimeFluorescence

本数据集包含ASAC 40项目第4航次的采样点位信息,该航次由法国极地补给船“L'Astrolabe”号于2007/2008年度执行。样品采集于2008年2月至3月期间。数据集同时涵盖叶绿素、类胡萝卜素、颗石藻(coccolithophorids)的相关数据,以及物种鉴定与计数结果。 项目公开摘要:本项目旨在探明南极海域内单细胞植物、动物、细菌与病毒的生态作用。我们将量化它们作为其他生物饵料的关键功能,以及其通过吸收二氧化碳(CO₂)和生成二甲基硫(DMS)以缓解全球气候变化的潜在影响,并明确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 40项目(ASAC_40)相关的其他元数据记录。 本数据集包含以下字段: 1. 管标签(Tube label) 2. 日期(UTC) 3. 时间(UTC) 4. 当地时间(十进制小时) 5. 根据经度计算得到的实际太阳当地时间(十进制小时)(注:此时间与时区无关) 6. 经度:十进制度数/度分格式 7. 纬度:十进制度数/度分格式 8. 海水温度(摄氏度) 9. 海冰存在/缺失 10. 卢戈氏瓶编号——浮游植物鉴定用显微镜样品编号(仅内部使用) 11. 高效液相色谱(HPLC)剩余体积——用于HPLC色素分析的过滤体积(仅内部使用) 12. 用于HPLC分析的过滤体积 13. 颗石藻分析剩余体积 14. 颗石藻托盘编号(仅内部使用) 15. 颗石藻托盘位置编号 16. 网采样品时间 17. 荧光值
