Biological characteristics, liver metal concentrations, habitat biogeochemistry and habitat contamination sources of UK otters (2006-2017)

The dataset details the biological characteristics and concentrations of toxic metals/semi-metals in liver tissue from 278 Eurasian otters (Lutra lutra) that died across England and Wales during the period 2006-2017.

For each otter carcass, location (National Grid Reference) was recorded. These locations were used to collate data describing spatial variation in stream and soil biochemistry, weather, and potential anthropogenic sources of contaminants in the otter's habitat from a range of sources.

This data was collected as part of the Cardiff University Otter Project. This project was supported in part by a grant from the Esme Fairbairn Foundation. The CEH contribution was supported the Natural Environment Research Council award number NE/R016429/1 as part of the UK-SCaPE programme delivering National Capability. This study contains model estimates of topsoil properties [Countryside Survey] and British Geological Survey data owned by © NERC as well as Ordnance Survey data owned by © Crown copyright and database right 2007.

本数据集详细记录了2006至2017年间，在英格兰与威尔士范围内死亡的278只欧亚水獭（Lutra lutra）的肝脏组织中有毒金属与半金属的生物学特征及其浓度水平。
针对每一具水獭尸体，均记录了其所在的国家网格参考坐标（National Grid Reference）。依托这些位置数据，研究人员整合了多源信息，涵盖水獭栖息地内溪流与土壤的生物化学特征、气象条件，以及栖息地内潜在人为污染物来源的空间分布差异。
本数据集系卡迪夫大学（Cardiff University）水獭项目的采集成果。该项目得到了埃斯梅·费尔贝恩基金会（Esme Fairbairn Foundation）的部分资助。CEH的相关工作得到了自然环境研究委员会（Natural Environment Research Council，NERC）编号为NE/R016429/1的拨款支持，作为英国-SCaPE计划（UK-SCaPE）的一部分，该计划旨在提供国家科研能力支撑。本研究包含《乡村调查》（Countryside Survey）中的表层土壤属性模型估算数据、由NERC持有版权的英国地质调查局（British Geological Survey）数据，以及受皇家版权（Crown Copyright）与数据库权益保护的2007年英国地形测量局（Ordnance Survey）数据。
