The system is composed of a Digital Barometer (Vaisala PTB-210), an R.M Anemometer (Young 05103) and a Humidity-Temperature Meteorological sensor (Rotronic MP101). The system continuously recorded Atmospheric pressure, Wind Speed and Direction, Air temperature and Humidity every 4 seconds for the CCGS Amundsen expeditions between 2004 and 2021. No data was collected in 2012 since the vessel was undergoing maintenance (dry docks). The true wind was directly calculated by the system using the ship's gyrocompass, the recorded apparent wind and Global Positioning System (GPS) data (speed and track of the ship from POS-MV and C-NAV Differential Global Navigation Satellite System (DGNSS) Precise Point positioning systems). Then the AVOS system averaged the data at 10 minute or hourly intervals. Outliers and suspicious measurements were removed from the dataset and the resulting controlled data are provided at 10 minute or hourly intervals for each day of the expeditions.

Two sets of controlled data are provided for each year of expedition. The first set is at time intervals of seconds for every day of the cruise and the second set is at 15 minute intervals. The data consist of Latitude, Longitude, Heading, Roll, Pitch, Heave, Track, Speed and Global Positioning System (GPS) sources at the second time intervals. The vessel's tracks in *.kml (Google Earth format) were derived from the 15 minute time intervals dataset and are also provided. Data before 2020 are presented in INT format; an internal text based format adopted by ArcticNet since the 2003. For the year 2020 and afterward, Amundsen Science has adopted CSV (Comma Separated Value) format to support its new policy on Open Data and Open Science. The corresponding ship tracks are presented in *.gpkg (Geopackage format: https://www.geopackage.org/) (external link) after 2020. Research programs participating in the Amundsen expeditions between 2003 and 2017 were CASES, ArcticNet, IPY-CFL, Solas, Geotraces, Malina, IOL and BP, Jamstec, Netcare, Weston, BREA, iBO and GreenEdge.\n\ncdm_data_type = Trajectory\nVARIABLES:\nplatform_name\nplatform_id (Platform WMO ID)\nfilename (Source File Name)\ncruise_number\ntime (seconds since 1970-01-01T00:00:00Z)\nlatitude (degrees_north)\nlongitude (degrees_east)\nHeading (Vessel Heading, degrees_north)\nRoll (Vessel Roll, degrees)\nPitch (Vessel Pitch, degrees)\nHeave (Vessel Heave, meter)\nTrack (Vessel True Direction, degrees_north)\nSpeed (Vessel True Speed, knots)\nGPS (GPS source, 1)\n https://erddap.amundsenscience.com/erddap/metadata/fgdc/xml/amundsen12447_fgdc.xml https://erddap.amundsenscience.com/erddap/metadata/iso19115/xml/amundsen12447_iso19115.xml https://erddap.amundsenscience.com/erddap/info/amundsen12447/index.htmlTable https://www.polardata.ca/pdcsearch/PDCSearchDOI.jsp?doi_id=12447 (external link) https://erddap.amundsenscience.com/erddap/rss/amundsen12447.rss https://erddap.amundsenscience.com/erddap/subscriptions/add.html?datasetID=amundsen12447&showErrors=false&email= Amundsen Science amundsen12447
