Hull Mounted ADCP Current Data Collected by the CCGS Amundsen in the Canadian Arctic

The CCGS Amundsen is equipped with a RDI ADCP Ocean Surveyor (RDI os150), a ship-mounted current meter attached to the hull of the ship. The ship is also equipped of ice windows to protect the system while sailing through harsh arctic conditions. The current meter records continuous measures of the current along the ship transit route using a 150KHz sonar capable of covering the first 450m of the arctic water column. Since 2015 data are controlled using the Common Oceanographic Data Access System (CODAS, https://currents.soest.hawaii.edu/home/software/) of the University of Hawai'i, also adopted by the NOAA-National Centers for Environmental Information (NOAA-NCEI) to create the Joint Archive for Shipboard ADCP. Data are provided in NetCDF formats and follow the COARD (Cooperative Ocean/Atmosphere Research Data) convention. Detailed information and metadata are available in the documentation of the archive and in-built metadata files. Raw data since 2004 are available on demand.
