    AbstractThe Emine’90 cruise is the second study of the Bulgarian national program for mapping the Bulgarian Black Sea shelf in a scale of 1:100,000. It was performed by the RV “Akademic” from 06 to 28 September, 1990. The principal database for the survey is a set of 20 echo-sounder and shallow seismic profiles with a line spacing of about 400 m trending in 120 ESE - 300 WNW direction and five lines perpendicular to them with a total length of about 320 km. The dataset covers an area along the shelf break in water depths from 80 m to more than 500 m offshore Southern Bulgaria. The echo-sounder investigations were made by SIMRAD - EA200 echo-sounder. Shallow seismic survey was carried out by “boomer” as sound source and 2 m length streamer with a group of 10 couples of hydrophones connected in parallel. The reflected signals were recorded on a wet-paper graphic recorder “Inei-P” within a frequency range of 480 Hz to 2,100 Hz with a central frequency of about 1,200 Hz. The recorded length was 0.4 sec with penetration of up to 0.250 sec (average 0.15 sec) bellow seabed. The vertical resolution of the boomer sections approximates 0.8-1.0 m and the quality of data is very good. Position fixing was undertaken by GPS – Navy Star navigation system, with an accuracy of near 0.01 nautical mile (about 20 m). Boomer sections are available as scanned images.
