AB: A study of mid-altitude polar cleft turbulence observed by CLUSTER-II spacecraft is presented. Using CLUSTER-II dayside perigee passes during summer 2001, the multi-instrument capabilities of the mission allows a detailed investigation of particles and waves commonly observed in regions adjacent to the polar cusp. It is found that in the ULF frequency range, kinetic Alfven waves associated with filamentary currents are identified in these regions. Their origin as well as their effect on the local plasma in terms of acceleration and/or heating of electrons and ions is investigated.
