This dataset of Autonomous Underwater Vehicles, such as Gliders and AutoSub Long-Range (ALR), managed by the British Oceanographic Data Centre (BODC) contains UK-funded worldwide campaigns of gliders since 2015 and ALRs since 2019. Glider and ALR deployments collect pressure, temperature, conductivity, and salinity through CTD sensors. Each platform’s logger records: platform attitude, water velocities, depth (pressure), and engineering variables. Additional sensors collecting: optical backscatter, chlorophyll fluorescence, turbulence microstructure, irradiance, and photosynthetically active radiation (PAR) data are mounted on each platform according to individual project objectives. Measurements are decimated for transmission and sent to BODC via satellite in near-real-time, where data are curated, then delivered in the OG1.0 Community (NetCDF) and raw binary format on ERDDAP for open access projects, in addition to the provision of metadata in JSON format. Near-real-time and recovery (i.e. the data from the SD card upon platform recovery) versions of the data are available. The metadata contain information about project, campaign objectives, funding, event metadata, platform and sensors, and measured parameters and units.
