  We investigate high resolution spectroscopic and imaging observations from
the CRisp Imaging SpectroPolarimeter (CRISP) instrument to study the dynamics
of chromospheric spicule type events. It is widely accepted that chromospheric
fine structures are waveguides for several types of magnetohydrodynamic (MHD)
oscillations, which can transport energy from the lower to upper layers of the
Sun. We provide a statistical study of 30 high frequency waves associated with
spicule type events. These high frequency oscillations have two components of
transverse motions: the plane of sky (POS) motion and the line of sight (LOS)
motion. We focus on single isolated spicules and track the POS using time
distance analysis and in the LOS direction using Doppler information. We use
moment analysis to find the relation between the two motions. The composition
of these two motions suggests that the wave has a helical structure. The
oscillations do not have phase differences between points along the structure.
This may be the result of the oscillation being a standing mode, or that
propagation is mostly in the perpendicular direction. There is evidence of fast
magnetoacoustic wave fronts propagating across these structures. To conclude,
we hypothesize that the compression and rarefaction of passing magnetoacoustic
waves may influence the appearance of spicule type events, not only by
contributing to moving them in and out of the wing of the spectral line but
also through the creation of density enhancements and an increase in opacity in
the Halpha line.
