In March and April of 1972, 4 transient undercurrents were associated with eddies at depths between 50 and 300 m in the Arctic Ocean. The velocity profile was parabolic with a maximum of 40 cm s-1) at 150 m. 2 of the eddies were anticyclonic and 2 cyclonic. The eddies persisted at least several days, they were 10-20 km in diam, and were separated by 20-50 km. The subsurface currents in the eddies were swifter than those in the upper mixed layer, with little correlation between the 2 levels. The eddies are believed to have their origin in the instability of the basic baroclinic current.
