ThermoSalinoGraph (TSG) data collected by the CCGS Amundsen in the Canadian Arctic

Provide core physical oceanographic data for all arctic research teams onboard CCGS Amundsen and other interested scientists. The underway ThermoSalinoGraph (TSG) system records data on surface seawater temperature, salinity, fluorescence and sound velocity along the transit route. These data constitute ancillary data for all other data recorded during the CCGS Amundsen scientific expeditions by providing information on the prevailing physical oceanic conditions in which biological, chemical and physical samplings were conducted. They also provide long-term records of the basic parameters central to the study of physical oceanographic processes, more specifically water column structure, water masses characteristics and oceanic circulation, in the Canadian Arctic Ocean.
