Ultra-low frequency (ULF) wave activity over the northern and southern terrestrial polar caps and at polar cap boundary regions is analyzed using Cluster Electron Drift Instrument (EDI), Flux Gate Magnetometer (FGM) and Cluster Ion Spectrometry (CIS) data. The February and March Cluster orbits lie mainly in the noon-midnight meridional plane with perigee at midnight. The open, polar cap for these orbits is bounded on one side by the nightside plasmasheet boundary layer and on the other by the dayside, high-latitude, poleward cusp boundary. Preliminary statistics of oscillation characteristics for the February and March orbits of 2001-2004 are presented. These statistics, as well as selected, energetic events, suggest an organization of the data in terms of three main magnetic field line topologies: those field lines adjacent to the poleward dayside cusp, those extending into the tail-lobe, and those adjacent to the nightside plasmasheet boundary layer. Possible source mechanisms suggested by this organization are discussed.
