One seamount locates at (0km, -19km).
The dominant tendency is for the vortex to
circumnavigate the vortex cyclonically, and for
the bulk of this trajectory to occur with minimal
actual contact of hte Meddy with the seamount. This
characteristic of nearly all of hte experiments that
we have conducted and can be understand by appealing
to the concept of image vortices inside the seamount
and their kinematic effect on the imping Meddy.

One seamount locates at (0km,26km).
There is considerable distortion of the core around the seamount at the vortex effectively
breaks. The organizing tendencies of the like-signed anticyclonic vorticity however holds
together clumps of the initial vortex, permitting two groupings of like-signed vorticity to exit the seamount. These clumps,
each contained within lengths comparable to a deformation radius, form the nuclei from which the
subsequent vortices emerge. Such collision is common.

One seamount locates at (0km,42km).
The vortex stagnates in the near neighborhood of the cylinder boundary, where it spends quite some time.
It is held together by the integrity of its core but undergoes constant distortion due to the shearing effects
of the mean flow and the vortex images. Eventually the core becomes too weak to maintain its position
against mean advection and a considerably reduced core is swept anticyclonically about the seamount. It
has a little more than hald its pre-collision point vortex population at the end of the experiement.
