  Aims. We study the coherency of solar spicules intensity oscillations with
increasing height above the solar limb in quiet Sun, active Sun and active
region using observations from HINODE/SOT. Existence of coherency up to
transition region strengthens the theory of the coronal heating and solar wind
through energy transport and photospheric oscillations. Methods. Using time
sequences from the HINODE/SOT in Ca II H line, we investigate oscillations
found in intensity profiles at different heights above the solar limb. We use
the Fourier and wavelet analysis to measure dominant frequency peaks of
intensity at the heights, and phase difference between oscillations at two
certain heights, to find evidence for the coherency of the oscillations.
Finally, we can calculate the energy and the mass transported by spicules
providing energy equilibrium, according to density values of spicules at
different heights. To extend this work, we can also consider coherent
oscillations at different latitudes and suggest to study of oscillations which
may be obtained from observations of other satellites.
