| Summary: | PolarFront Sailbuoy ADCP 2021 https://doi.org/10.5281/zenodo.7463096 This dataset contains ocean currents measured using acoustic Doppler current profiler attached to sailing autonomous surface vehicle ADCP , while on campaign at 70–77N in the Barents Sea for the PolarFront research project, between 16 May and 25 July 2021. The ADCP is equipped with a Aanderaa DCPS 5400 operating at 600 kHz, mounted in the keel at –0.2 m. Space/time coverage Time: 2021-05-16T13:45:00Z/2021-07-25T13:15:00Z Space: [20.5,70.0,33.0,76.8] ([W,S,E,N]) Data distributions Datalogger (text files) The primary distribution consists of 2 datalogger text files retrieved post-mission from sailbuoy internal storage. The files are the full scale original data records, as captured by the internal sofware of manufacturer Offshore Sensing . DATA.TXT: Position and sensor metadata DCPS.TXT: Full resolution ADCP data GeoJSON For increased data interoperability, a GeoJSON file is also included, consisting of Point features like the following: { "geometry": { "coordinates": [30.11165, 76.438894], "type": "Point" }, "properties": { "time": "2021-05-19T22:45:00Z", "TTFF": 11, "Count": 24, "Commands": 0, "TxTries": 1, "ONT": 635, "DiskUsed": 0.783123, "Files": 0, "I": 0.01564, "V": 13.195122, "Temperature": 4.06502, "DCPSStatus": 0, "DCPSOnMin": 10, "DCPSSpeed": 0.329999, "DCPSDirection": 233.233643 }, "type": "Feature" } The GeoJSON file is derived from DATA.TXT and contains the full position and DCPS metadata log in a standard/machine-parsable format, including coordinated universal time following RFC 3339 / ISO 8601 . Data formats and interoperability Both of the datalogger text files are in non-standard vendor formats. The DCPS text file format is described in the vendor manual . The file contains blocks of data like the following [abbreviated with …]: Sensorlog opened 25.07.2021 09:45:22 GPS: 25.07.2021 09:45:22 70.41890 20.86238 % StartupInfo 5400 278 Mode AADI Smart Sensor Terminal Protocol RS232 Protocol Version 3 Config Version 24 Initializing. ...
