Maritimes Region Barrow Strait Flow Observational Program Rosette Vertical Profiles

The Barrow Strait flow observational program started in 1998 and continued for 13 years to 2012. Barrow Strait is the widest of the 4 passages through the Canadian Archipelago making it an important monitoring location. The program explores the magnitude and variability of freshwater, heat and volume transports through the eastern Northwest Passage. The data measured included: profile CTD and time series temperature, salinity, density, currents, ice draft and ice drift velocity. The time series data collected was used to quantify the freshwater discharge from the Arctic Ocean through Barrow Strait into the northwest Atlantic, and link variability in this freshwater outflow to large scale weather patterns. Annual analysis performed on the collected data include: low-pass filtering, power spectra, progressive vector diagram, tidal analyses, seasonal and monthly averaged stats, mean flow, and ice velocities. Data from the program, along with a description of the methods used, have been published annually in the Canadian Data Report of Hydrography and Ocean Sciences report number 190 to 195, 173, 167, 166, 165, 161, and 157.
