GA0334 Vlaming sub-basin Species identification of worms from grab
收藏资源简介：
The Vlaming Sub-basin Marine Survey GA-0334 was undertaken by the RV Solander in March and April 2012 as part of the Commonwealth Government's National CO2 Infrastructure Plan (NCIP). The purpose was to acquire geophysical and biophysical data to help identify sites suitable for the long term storage of CO2 within reasonable distances of major sources of CO2 emissions. This dataset contains identifications of animals collected from 31 Van Veen grabs deployed during GA-334. Sediment was elutriated for ~ 5 minutes over a 500um sieve. Retained sediments and animals were then preserved in 70% ethanol for later laboratory sorting and identification. During sorting, all worms were separated and sent to Infaunal Pty Ltd for identification to species or operational taxonomic unit (OTU). Lynda Avery completed identifications on 17 April 2013, and specimens were lodged at the Museum of Victoria in May 2013. Blank cells in the species matrix indicate a value of '0'. Site refers to the station number, and grab refers to the cumulative number of grabs performed at that point in the survey. Data is presented here exactly as delivered by the taxonomist, and Geoscience Australia is unable to verify the accuracy of the taxonomic identifications. See GA Record 2013/09 for further details on survey methods and specimen acquisition.
弗拉明次盆地海洋调查GA-0334由索兰德号研究船（RV Solander）于2012年3至4月执行，作为澳大利亚联邦政府国家二氧化碳基础设施计划（National CO2 Infrastructure Plan, NCIP）的一部分。本次调查旨在获取地球物理与生物物理数据，以识别距离主要碳排放源合理范围内、适合长期封存二氧化碳的场址。 本数据集包含GA-334调查中31台范温采泥器（Van Veen grab）采集的动物标本鉴定结果。采集的沉积物经500微米筛网淘洗约5分钟，随后将留存的沉积物与动物标本置于70%乙醇中保存，用于后续实验室分选与鉴定。分选过程中，所有蠕虫类标本均被分离，并送至Infaunal Pty Ltd公司进行物种或操作分类单元（OTU）鉴定。琳达·埃弗里（Lynda Avery）于2013年4月17日完成全部鉴定工作，标本于2013年5月被馆藏于维多利亚博物馆。物种矩阵中的空白单元格代表数值为'0'，其中“站位”对应测站编号，“采泥器”对应本次调查中该站位累计完成的采泥投放次数。 本次发布的数据完全按照分类学家提交的原始版本呈现，澳大利亚地质调查局（Geoscience Australia）无法验证本次分类学鉴定结果的准确性。 如需了解调查方法与标本采集的更多细节，请参阅GA档案2013/09。
