Species point records from 1992 SWW Tamar Estuary sublittoral sediment survey

In September 1992, a study was undertaken by Marine Biological and Chemical Consultants, on behalf of South West Water to investigate the sediments and benthic fauna of the River Tamar in the vicinity of SWW sewage outfalls at Ernesettle, Saltash, Camels Head and West Hoe. Multiple grab samples were taken by boat at each of seventeen stations on the 24th and 25th of September, 1992. Subsequent analyses included faunal identification combined with various sediment parameters (particle size distribution, heavy metal concentrations, bacteriological and viral loading and organic carbon content). The present study forms part of a wider study under the Plymouth Marine Scheme and is intended as a baseline survey prior to the upgrading of existing treatment works and the possible relocation of existing outfalls. Records currently considered sensitive have been removed from this dataset.

于1992年9月，应西南水务公司之委托，海洋生物与化学顾问公司对位于埃尔斯泰尔、萨尔特什、卡梅尔头部和韦斯特豪的西南水务污水处理厂附近的泰姆河沉积物和底栖动物进行了研究。1992年9月24日和25日，在十七个站点通过船只采集了多个抓取样本。随后的分析包括动物种类鉴定以及多种沉积参数（颗粒大小分布、重金属浓度、细菌和病毒负荷以及有机碳含量）。本项研究是普利茅斯海洋计划更大规模研究的一部分，旨在在现有处理设施升级和现有排放口可能搬迁之前，进行一项基础性调查。目前认为敏感的记录已被从本数据集中移除。
