1998 Fawley Aquatic Research Labs Ltd, Hydrocyclone discharge area, Furzey Island, Dorset, Benthic Day grab sampling survey

These records all relate to "Coughlan, Bamber, Somes (1998) Furzey Island Hydrocyclone:1998 Benthic Survey (FCR 297/98)" A copy of the report is held at Dorset Environmental Records Centre. This report gives the findings of a benthic survey carried out in July 1998 - the first post-commissioning study of the hydrocyclone facility. The hydrocylcone abstracts sea water from Poole Harbour for down well injection. The sea water intake is close to the sea bed at the head of a wooden jetty on Furzey Island. Six sites were surveyed, with three replicate 'Day' grab samples taken from each site. The abundance of species at each station has been entered onto the database rather than the abundance of species in each sample. Station position fixing was by GPS and by reference to landmarks, however in the report they are only displayed on a map and not stated directly. Therefore, the coordinates used in the database have been derived from a combination of the Admiralty chart (unknown scale) in the report in conjunction with MapInfo. The methods and sampling stations (where possible) were the same as those used in a baseline benthic survey of the discharge area carried out in December 1995, and results from the two surveys have been compared in this study.本数据集所有记录均关联《考夫兰、班伯、索姆斯（1998）：弗兹岛水力旋流器1998年度底栖生物调查（benthic survey）报告（FCR 297/98）》，该报告副本留存于多塞特环境记录中心（Dorset Environmental Records Centre）。 本报告呈现了1998年7月开展的底栖生物调查成果——这是针对该水力旋流器（hydrocyclone）设施的首次投产后研究。该设施从普尔港抽取海水用于井下注入，其海水取水口位于弗兹岛一处木质码头顶端，紧邻海床。本次调查共设置6个采样站点，每个站点采集3份平行“日间”抓斗采样样本。数据库中录入的为各站点的物种丰度，而非单份样本的物种丰度。站点定位采用全球定位系统（GPS）结合地标参照的方式，但报告中仅将站点位置标注于地图，未直接给出具体坐标。因此，本数据库所采用的坐标系结合报告中的英国海军海图（比例尺未知）与MapInfo软件共同推导得出。本次调查采用的方法与采样站点（若可行）与1995年12月针对排放区域开展的基线底栖生物调查一致，本研究亦对两次调查的结果进行了对比分析。
