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 2003/2004 season. Samples were collected between January and February of 2004. 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:Tube Labelour useSample#our useDate(UTC)Time(UTC)Shorthand entry code - ignoreTime(UTC)FormattedUse thisLong DegdegreesLong MinminutesLongDecdecimaldegreesLat DegdegreesLat MinminutesLatDecdecimaldegreesLocal time (dec hrs)actual solar local time (decimal hours) calc from longitudeDOES NOT EQUAL TIME ZONESea TempIcepresent/absentLugol's#microscope sample number for phytoplankton ID (Our use only)HPLC Volvolume filtered for HPLC pigment analysis (Our use only)Cocco Volvolume filtered for coccolithophorid counts (Our use only)Cocco tray No.(Our use only)Location:DCM: Deep chlorophyll maximumThermo: Thermocline
本数据集包含2003/2004航季法国极地补给船“阿斯托拉贝号(L'Astrolabe)”第2航次ASAC项目40的采样点位信息。采样工作于2004年1月至2月间完成。数据集同时包含最终成果数据集,涵盖叶绿素、类胡萝卜素、颗石藻(coccolithophorids)相关信息,以及物种鉴定与计数结果。
项目公开摘要:本项目旨在探明南极水域中单细胞植物、动物、细菌与病毒的生态作用:量化其作为其他生物食物的核心生态功能,评估其通过吸收CO₂与生成二甲基硫(Dimethyl Sulfide, DMS)调节全球气候变化的潜在影响,并明确它们对气候变化的响应机制。
