The Canadian research icebreaker CCGS Amundsen is equipped with a Moving Vessel Profiler (c) (MVP), a multi-purpose instrument used to collect both shallow and deep water data sets, without the need to stop the vessel. Data on physical and chemical characteristics of the water column are collected during transects along which several consecutive casts of the MVP are conducted. The MVP was deployed during the Amundsen scientific expeditions, in the summer and fall of 2014 to 2016. The components of the system varied slightly throughout the year but typically included a Micro CTD (Temperature, Conductivity and Pressure), a Micro DO2 (Dissolved Oxygen), a Micro SV (Sound velocity and Pressure) and an ECOFLO (Fluorescence) and a C-Star (Transmittance) probe. The MVP data were corrected and then controlled by comparing them to CTD-Rosette and thermosalinograph (TSG) data when available. Variables are provided for every decibar (dbar) between the maximum and minimum pressure recorded for each cast. Detailed metadata and reports are included to provide more information.
