Temperature-depth profiles from dive computers, underwater cameras and Castaway microCTDs, collected during sea and hyperbaric chamber dives in Oban, Scotland (2020).

A collection of raw water temperature-depth-time profiles were recorded from a selection of dive computers, underwater cameras and Castaway microCTD devices. Data were collected at Oban recompression chamber (owned and managed by Tritonia Scientific), as well as during sea dives local to 56.42°N, 5.47°W, over a two-week period between 08/01/2020 and 07/02/2020. A number of different devices and models were tested during the study. Chamber dives were undertaken to test and compare device response time (29 devices over 11 dives) and accuracy (6 replicate dives). This was followed by local sea dives to further compare device accuracy. During each pair of sea dives (6 total), half of the devices were mounted on a frame with the remainder worn by two divers. For the subsequent dives in each pair, each device was switched to the alternate mounting position. Dive profiles were exported from individual dive computers into Subsurface open source software, then exported in ssrf (XML) format for each week of data collection. Profiles from all dive computers were combined for analysis. Castaway microCTDs and underwater camera profiles were exported as individual CSV files per dive. 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 in water temperature profiles collected from devices commonly carried by Scuba divers. The PhD project is 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 is additionally supported by Cefas Seedcorn (DP901D). The diving and chamber tests were supported through a NERC National Facility for Scientific Diving grant (NFSD/17/02).

本数据集收录了一批原始水温-深度-时间剖面数据，采集自多款潜水电脑、水下相机以及Castaway微型CTD（Castaway microCTD）设备。数据采集地点涵盖由Tritonia Scientific公司所有并运营的奥班减压舱，以及北纬56.42°、西经5.47°附近的近海区域，采集时段为2020年1月8日至2020年2月7日，共计两周。本研究共测试了多款不同型号的设备。舱内潜水实验共开展11次，共纳入29台设备以测试并对比其响应时间；另有6组重复舱内潜水实验，用于评估设备的测量精度。随后开展的近海潜水实验则用于进一步验证设备的测量精度。本次近海潜水共完成6组成对潜水作业，每组作业中半数设备被安装于固定支架，其余设备由两名潜水员随身佩戴；在每组作业的后续潜次中，所有设备均切换至另一安装方式。潜水电脑的剖面数据从各设备导出至Subsurface开源软件，随后按每周的采集时段分别保存为ssrf（XML）格式文件。所有潜水电脑的剖面数据将合并用于后续分析。Castaway微型CTD设备与水下相机的剖面数据则按每次潜水分别导出为独立的CSV文件。本数据为东英吉利大学Celia Marlowe博士学位项目的一部分，该项目旨在评估潜水员常用设备采集的水温剖面数据的精度与可靠性。该博士项目隶属于“下一代无人系统科学（Next Generation Unmanned Systems Science, NEXUSS）博士培训中心”，由自然环境研究理事会（Natural Environment Research Council, NERC）与工程与物理科学研究理事会（Engineering and Physical Science Research Council, EPSRC）联合资助（资助编号：NE/N012070/1），并获Cefas Seedcorn项目（编号：DP901D）额外支持。舱内与近海潜水实验的开展获得了NERC国家科学潜水设施专项拨款（资助编号：NFSD/17/02）。
