Temperature data from a public dive log application, acquired from recreational divers’ dive computers in the northern Red Sea (2000-2017)

A collection of raw dive computer data (latitude, longitude, date, time, minimum temperature, surface temperature and maximum depth) logged by unknown recreational divers and uploaded to a publicly available online dive logging application (divelogs.de) was exported and filtered for further analysis. The data were spatially restricted to the northern Red Sea: 23-30° N, 32-39.4° E. Only dives within standard recreational depths (maximum dive depth ≤ 40 m), years with more than 75 dives per year and with a spread of dives across most months were retained (2000 to 2017). The data were processed in R version 4.2, using the tidyverse suite of packages. A 15 arc-second (approximately 0.5 km) resolution bathymetric grid of the area was downloaded from GEBCO, allowing bathymetric depths associated with each dive location to be found using the marmap get.depth function in R. Data were collected as part of Celia Marlowe’s PhD project at the University of East Anglia, which aimed to assess the precision and accuracy of water temperature profiles collected from devices commonly carried by Scuba divers. The PhD project was part of the Next Generation Unmanned Systems Science (NEXUSS) Centre for Doctoral Training, funded by the Natural Environment Research Council (NERC) and the Engineering and Physical Science Research Council (EPSRC) (NE/N012070/1), and was additionally supported by Cefas Seedcorn (DP901D).

本数据集汇集了未知休闲潜水员在公开在线潜水日志应用（divelogs.de）上记录并上传的原始潜水计算机数据（纬度、经度、日期、时间、最低水温、水面水温及最大深度）。数据在空间上被限制在北红海区域：23-30° N，32-39.4° E。仅保留了在标准休闲潜水深度内（最大潜水深度≤40米）、每年潜水次数超过75次且潜水分布覆盖多数月份的潜水记录（2000年至2017年）。数据在R语言版本4.2中使用tidyverse软件包集进行处理。从GEBCO下载了该区域的15弧秒（约0.5公里）分辨率的水深网格，利用R中的marmap get.depth函数，可以找到与每个潜水位置相关联的水深。数据收集作为东安格利亚大学Celia Marlowe博士项目的一部分，该项目旨在评估由潜水员常用设备收集的水温剖面的精确度和准确性。该博士项目是下一代无人系统科学（NEXUSS）博士培训中心的研究项目，由自然环境保护研究委员会（NERC）和工程与物理科学研究委员会（EPSRC）（NE/N012070/1）资助，并得到Cefas Seedcorn（DP901D）的支持。
