Grant,

Turkey has agreed maritime boundaries with Bulgaria (in 1997) and
Ukraine (agreements with the USSR in 1986 and 1987, confirmed by an
exchange of notes with Ukraine in 1994). The two lines do not quite
meet - there is a gap of 10" of latitude and 5" of longitude between
their terminal points - but both agreements contain provisions for
adjusting the final section of the boundary, so presumably they will be
joined up in due course.

There are no maritime boundary agreements between Bulgaria-Romania or
Romania-Ukraine, so the map on the Veridian website is misleading. In
the actual Global Maritime Boundaries Database the lines are marked as
hypothetical equidistance lines, but they do converge on what appears to
be a quadripoint.

Based on a very quick graphical plot on a paper chart, the
Bulgaria-Romania and Romania-Ukraine equidistance lines do appear to
meet quite close the (almost) agreed Bulgaria-Turkey-Ukraine tripoint.
If the two boundaries are agreed on the basis of equidistance, it would
seem to make sense from an administrative perspective for the four
states to agree that their boundaries should meet at a single point.
However, before anyone gets too excited, I should point out that there
is a known dispute between Romania and Ukraine over whether Zmeinyy
(Serpent's) Island should be allowed to influence the alignment of the
Romania-Ukraine boundary. After a long-running dispute Romania finally
recognised Ukrainian sovereignty over this small, uninhabited island in
1997, but it has subsequently argued that it should be ignored for
delimitation purposes. The area around the island has significant
hydrocarbon potential and it seems unlikely that the two sides will find
a mutually acceptable solution in the near future. Even if they do, I
suspect that it will involve a compromise which would probably preclude
the possibility of a maritime quadripoint....
