资源简介:
Locations of sampling sites for ASAC project 40 on rotation 4 of the French polar supply ship L'Astrolabe in the 2004/2005 season. Samples were collected between February and March of 2005.The final dataset will contain 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)LongDecdecimaldegreesLatDecdecimaldegreesLocal time (dec hrs)actual solar local time (decimal hours) calc from longitudeDOES NOT EQUAL TIME ZONESea Tempdegrees CelsiusIce present/absentLugol's#microscope sample number for phytoplankton ID (Our use only)HPLC Vol volume filtered for HPLC pigment analysis (Our use only)Cocco Vol volume filtered for coccolithophorid counts (Our use only)Cocco tray No.(Our use only)Net Sample Time
2004/2005航季,法国极地补给船“星盘号”(L'Astrolabe)执行ASAC项目40第4轮任务的采样点位分布。样本采集于2005年2月至3月期间。最终数据集将涵盖叶绿素、类胡萝卜素、颗石藻(coccolithophorids)相关数据,以及物种鉴定与物种计数结果。
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、细菌与病毒的生态功能:量化其作为其他生物食物的核心作用,评估其通过吸收二氧化碳(CO₂)与生成二甲基硫(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。
