On the Barents Sea Polar Front in summer and interpretations of the associated regional oceanography using an Arctic Ocean general circulation model
In August 1992 a combined physical oceanography and acoustic tomography experiment was conducted to describe the Barents Sea Polar Front (BSPF) and investigate its associated mesoscale phenomena. The study area was an 80 by 70 km grid east of Bear Island where the front exhibits topographic trapping...

In August 1992 a combined physical oceanography and acoustic tomography experiment was conducted to describe the Barents Sea Polar Front (BSPF) and investigate its associated mesoscale phenomena. The study area was an 80 by 70 km grid east of Bear Island where the front exhibits topographic trapping along the northern slope of the Bear Island Trough. CTD, current meter and CP data, combined with tomographic cross-sections, presented a highly resolved picture of the front in August. All hydrographic measurements were dominated by tidal signals with the strongest signatures associated with the M2 and S2 semidiurnal species. Tomographic cross sections indicated a high-frequency (approx 16 cpd) upslope motion of filaments of Norwegian Atlantic Water (NAW) origin at the front.
