Conductivity, temperature, as well as other properties at different depths are important characteristics of seawater, with significant effects on the ecology of the ocean in the Arctic. To gain an idea about these seawater properties south of Victoria Island, CTD samplings have been performed from the Martin Bergmann research vessel in the Cambridge Bay, Dease Strait and Queen Maud Gulf by CJ Mundy of the University of Manitoba. Additionally, in order to determine the ideal depth of the CHARS seawater intake pipe, and to meet the required salinity and temperature of the seawater flown into CHARS aquaria, a more targeted CTD sampling has been performed in a section of the east arm of Cambridge Bay offshore of the future CHARS site. This has been accomplished both with a smaller CTD probe launched from a skiff by CHARS staff (data in Ruskin file with extension .rsk, and same data in comma-separated text file, .csv, and Excel spreadsheet, .xls), as well as the larger CTD probe of the 'Martin Bergmann' research vessel by CJ Mundy (data in text files with .int extension). : Purpose: Conductivity, temperature and depth (CTD) measurements have been performed in the eastern end of Cambridge Bay offshore of the future site of the Canadian High Arctic Research Station (CHARS). This preliminary investigation will help establish the ideal location and depth of the seawater intake pipe for CHARS, and meet the salinity and temperature targets for seawater for the CHARS aquaria. CTD measurements in other areas of Cambridge Bay, as well as in Dease Strait and Queen Maud Gulf have been performed as part of a general investigation of seawater properties at different depths in the waters south of Victoria Island. : Summary: Conductivity, temperature, salinity and other seawater properties have a great importance in the ecology of the ocean in the Arctic. CTD samplings have been performed from the 'Martin Bergmann' vessel in Cambridge Bay, Dease Strait and Queen Maud Gulf. In order to establish the proper location and depth of the seawater intake pipes for the aquaria at CHARS, more targeted CTD measurements have been performed in the eastern arm of Cambridge Bay, offshore of the future CHARS site both from the 'Martin Bergmann' research vessel and a skiff.
