No abstracts are to be cited without prior reference to the author.An instrumented mooring array across Barrow Strait in the Canadian Arctic Archipelago has provided a 10 year data time series that has been used to determine freshwater and heat transports through this important pathway connecting the Arctic Ocean and the northwest Atlantic Ocean. Measurements indicate that 20% of the total freshwater transport out of the Arctic Ocean passes through this 65 km wide passage, but also demonstrate large seasonal and inter-annual variability in these transports. The timing and duration of a short ice free period in the Strait also varies from year to year, resulting in different water temperature, light and mixing conditions throughout the biological growing season. Here, backscatter data from the acoustic Doppler current profilers (ADCPs) used to provide the transport time series, are analysed to study the behaviour, and temporal variability in the relative biomass of the zooplankton population.
