The Canadian research icebreaker CCGS Amundsen is equipped with multi-plankton sampler system called Hydrobios. The MultiNet Type Maxi, part of the system, is used for vertical collections. An integrated CTD unit is also integrated to the system and allows recording of the sampled water characteristics. This dataset is composed of CTD profiles and specific data for the volume of water going through the nets during their operation. The Hydrobios was deployed during the Amundsen scientific expeditions in the summer and fall between 2003 and 2018 with the exception of 2004, 2005, 2009, 2011 and 2012, where no data is available. The integrated CTD sensors are from the Hydrobios company itself. The Hydrobios-CTD data were corrected and controlled by comparing them to CTD-Rosette data when available. Outliers and suspicious measurements were removed from the dataset. Variables are provided for every 2 decibars (dbar) between the maximum and minimum pressure recorded for each cast. Research programs participating in the Amundsen expeditions between 2003 and 2018 include CASES, ArcticNet, CFL, Geotraces, Malina, IOL and BP, BREA, Weston, Netcare, JAMSTEC, Statoil, iBO and GreenEdge. : Purpose: Provide core physical oceanographic data for all arctic research teams onboard the CCGS Amundsen and other interested scientists. The Hydrobios is equipped with Conductivity, Temperature, Depth (CTD) sensors recording temperature, salinity, and pressure data in the water column. This dataset is composed of CTD profiles and specific data for the volume of water going through the nets during their operation. CTD 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. For some years, the data collection surpasses the Canadian Arctic border, however, the main goal of this project is to collect data from the Canadian Arctic Ocean. : Summary: Not Applicable
