Many existing theories linking broadband ELF wave activity (BBELF) to ion energization and outflow are based on the
gyro-resonant heating of ions. Recent studies on the properties of these broadband waves show that other mechanisms may be
more relevant. Using data from the Polar satellite, we will present an analysis of the observed relationship between the
broadband electric field spectrum and ion energization across the cusp.
