Role of Antarctic marine protists in trophodynamics and global change and impact of UV-B on these organisms - Rotation 0 of the Astrolabe - 2007/2008 samples

This dataset contains locations of sampling sites for ASAC project 40 on rotation 0 of the French polar supply ship L'Astrolabe in the 2007/2008 season. Samples were collected between October and November of 2007. 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

本数据集收录了2007/2008航季法国极地补给船L'Astrolabe（阿斯托洛拉号）执行ASAC项目40第0轮次的采样站点位置信息，采样工作于2007年10月至11月间开展。本数据集同时包含叶绿素、类胡萝卜素、颗石藻相关数据，以及物种鉴定与计数信息。
项目公共摘要：本项目旨在探究南极水域中单细胞植物、动物、细菌与病毒的生态作用：量化它们作为其他生物饵料的关键功能，分析其通过吸收二氧化碳与生成二甲基硫醚（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效应的响应机制。
