1992 - 2012 Centre for Environment, Fisheries & Aquaculture Science (Cefas) Seawater temperature records for the UK Shelf - 10 - Citizen Science Diver Recorded Temperatures

This dataset has been extracted as part of an exercise to assemble "all" Cefas Temperature Data and publish it in a Data paper. It is one of 17 Cefas data sources assembled. This data source differs from the others in this collection because it arises from an investigation into the potential for Citizen Science to contribute to assessments of the marine environment. The dataset is derived from a database containing over 7,000 records of temperature data collected from temperature compensated dive computers. The lowest temperature is recorded from the thermal sensor. The unprocessed data were then subjected to a quality control process that compared the temperature with the relevant sea surface temperature (obtained from OSTIA – Operational Sea Surface Temperature and Sea Ice Analysis – `http://ghrsst–pp.metoffice.com/pages/latest_analysis/ostia.html`_ ). There was a linear correlation between the sea surface temperature and the recorded temperature at depth. Values exceeding a specified difference from the surface temperature (5°C) were excluded. This resulted in a quality assured dataset of just over 5,000 records (including freshwater and lake data). The subset of global dataset provided covers the UK shelf. The 5°C threshold is derived from previous analyses of the performance of dive computers. .. _`http://ghrsst–pp.metoffice.com/pages/latest_analysis/ostia.html`: http://ghrsst-pp.metoffice.com/pages/latest_analysis/ostia.html本数据集系为汇编‘全部’英国中央水产科学中心（Centre for Environment, Fisheries and Aquaculture Science, Cefas）温度数据并以数据论文形式发表的相关研究工作中提取所得，属于本次整合的17个Cefas数据源之一。 本数据源区别于本次整合的其他数据集，因其源自一项探究公民科学（Citizen Science）助力海洋环境评估潜力的研究。该数据集来源于一个数据库，其中包含超过7000条来自温度补偿式潜水电脑的温度记录，数据由热传感器采集得到最低温度值。随后，研究人员对未处理的原始数据开展质量控制流程：将采集到的温度与对应的海表温度进行比对，海表温度数据来源于业务化海表温度与海冰分析系统（Operational Sea Surface Temperature and Sea Ice Analysis, OSTIA），数据来源网址为<http://ghrsst-pp.metoffice.com/pages/latest_analysis/ostia.html>。 海表温度与实测的水深温度存在线性相关关系。研究人员剔除了与海表温度偏差超过5℃的记录，最终得到经过质量验证的数据集，共包含5000余条记录（涵盖淡水及湖泊相关数据）。本次提供的全球数据集子集覆盖英国陆架海域。 本次采用的5℃偏差阈值，源自此前针对潜水电脑性能开展的分析研究。
