资源简介:
Dataset includes locations of sampling sites for ASAC project 40 on voyage 6 of the Aurora Australis in the 2007/2008 season. Samples were collected between March and April of 2008. The dataset also contains information on chlorophyll, carotenoids, coccolithophorids and species identification and counts.Four datasets are currently included in this download - a CTD filtration log, an HPLC filtration log, a CHEMTAX file and a Pigments file.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:HPLC DatasetTube LabelDate (UTC)Time (UTC)LatitudeLongitudeSea TemperatureIce (Presence or Absence - 1 or 0)LugolsHPLCFlurometer - Chlorophyll aCommentsCTD DatasetTube labelStation NumberCTD NumberNiskin Bottle NumberDepth (m)Date (UT)Start time (UT)Stop time (UT)LatitudeLongitudeLugol's NumberHPLC Volume (ml)Temperature (degrees C)Comment
本数据集涵盖2007/2008航季南极光号(Aurora Australis)第6航次ASAC项目40的采样站位点位信息。样品采集于2008年3月至4月期间。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结果。本次下载共包含四类数据集:CTD过滤日志、高效液相色谱(HPLC)过滤日志、CHEMTAX文件与色素文件。
项目官方摘要:本研究计划旨在探究南极水域内单细胞植物、动物、细菌与病毒的生态功能:量化它们作为其他生物饵料的核心生态作用,解析其通过吸收CO₂并生成二甲基硫(DMS)调节全球气候变化的潜在影响,并明确它们对气候变化效应的响应机制。
