International Bathymetric Chart of the Mediterranean (I.B.C.M.) Published by the Intergovernmental Oceanographic Commission of UNESCO

C. Morelli

UNESCO's Intergovernmental Oceanographic Commission published (1982), in cooperation with ICSEM, a new International Bathymetric Chart of the Mediterranean (10 sheets, scale 1:1,000,000). Almost 80% of the data were derived from the systematic survey of the Mediterranean performed by O.G.S., initially in cooperation with the La Spezia Saclant Centre (1961-1965; 112,000 km of tracks), subsequently for the CNR's first oceanographic program (1965-1972; 217,500 km of tracks). The area east to 26°20^primeE has been completed by Cambridge University.

The main technical specifications in the performance and the principal geologic and geophysical deductions will be outlined. It will follow a description of the cartographic preparation and realization.

The feasibility studies were initiated for the following maps: gravity anomalies, aeromagnetism, seismicity, Holocene sedimentation, and the Pliocene-Quaternary.
