The Arctic Ocean boundary current transports Atlantic-origin waters cyclonically for thousands of kilometers around the perimeter of the Eurasian and Canadian Basins, propagating temperature and salinity anomalies originating in the Barents and Greenland Seas into the Arctic Ocean. Transient tracer data collected at 22 locations provide a basin-wide, time-integrated view of the boundary current. We use these data to constrain a transit-time-distribution model of the Barents Sea Branch Water in the boundary current. The modeled mean velocity of the current is 2.5 ±0.5 cm s-1 and the mixing timescale between the boundary and the interior is 5-10 years.
