Wide-angle seismic refraction data were acquired in the eastern Black
Sea to delineate
the crustal structure of the rifted margins and to determine the
affinity (continental
v. oceanic) of thin crust in the centre of the basin. This information
will be used to
understand the formation of the eastern Black Sea and to gain generic
insights into
continental extension and rifting.
During the 22-day cruise, refraction data were collected along four
main profiles in
the eastern Black Sea.
Two profiles begin on the Turkish margin and continue into the basin
center.
One profile is oriented NW-SE and traverses across the thinnest crust
in
the centre of the basin.
The fourth profile crosses the Mid-Black Sea High, a buried basement
ridge that
separates the eastern and western basins.
Seismic data were also recorded by land seismometers positioned at the
ends of
three of the profiles onshore.
