  We have found evidence of bulk velocities following active galactic nucleus
(AGN) bubbles in the Virgo cluster and galaxy motions in the Centaurus cluster.
In order to increase the sample and improve our understanding of the
intracluster medium (ICM), we present the results of a detailed mapping of the
Ophiuchus cluster with {\it XMM-Newton} to measure bulk flows through very
accurate Fe~K measurements. To measure the gas velocities we use a novel
EPIC-pn energy scale calibration, which uses the Cu K$\alpha$ instrumental line
as reference for the line emission. We created 2D spectral maps for the
velocity, metallicity, temperature, density, entropy and pressure with a
spatial resolution of 0.25$'$ ($\sim 26$~kpc). The ICM velocities in the
central regions where AGN feedback is most important are similar to the
velocity of the brightest cluster galaxy (BCG). We have found a large interface
region where the velocity changes abruptly from blueshifted to redshifted gas
which follows a sharp surface brightness discontinuity. We also found that the
metallicities and temperatures do not change as we move outwards from the giant
radio fossil previously identified in radio observations of the cluster.
Finally, we have found a contribution from the kinetic component of $<25\%$to
the total energy budget for large distances.
