| Summary: | The Canadian research icebreaker CCGS Amundsen is equipped with BIONESS (Bedford Institute of Oceanography Net and Environmental Sampling System). It is a multiple-net sampler for zooplancton and micronekton (pelagic animals 1-10 cm in length). It uses a design with nets arranged horizontally rather than vertically. 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 BIONESS was deployed during the 2005, 2006, 2013, 2014 and 2016 Amundsen scientific expeditions in summer and fall. The Bioness-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 decibar (dbar) between the maximum and minimum pressure recorded for each cast. Research programs participating in the Amundsen expeditions between 2005 and 2016 include ArcticNet, IOL and BP, BREA, Weston, Netcare, JAMSTEC, iBO and GreenEdge. In-situ data belong to and are under the responsibility of the leading Nets scientists while physical and chemical data from the sensors are part of the Amundsen core data collection. : Purpose: Provide core physical oceanographic data for all arctic research teams onboard the CCGS Amundsen and other interested scientists. The Bioness 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 |
