Within the Ocean Margin Cluster (OMARC) and in close co-operation with the Euro-US “Eurostrataform” project, the objective of Promess is to obtain comprehensive transects across two Mediterranean Deltaic Margins, in the Gulf of Lions and in the Adriatic, where seismic data base are good and preservation of depositional sequences exceptional.
Promess 1 will use a geotechnical vessel for sampling long sections (50-300 m) and realise in situ measurements and downhole logging of shelf and upper slope sedimentary environments (50-300 m water depth). It will provide clues on:
. High resolution sequence stratigraphy on deltaic margins
. Processes of formation of strata and architecture of sediment
bodies from source to sink
. Slope stability
. Rapid climate changes
In order to process the ca. 700 m of coring and logging data, the project has been organized in 8 work-packages. To the great difference of IODP, most of the work will have to be done onshore, which implies a strong networking of European and North American laboratories.

During Year 1 of the project, assessment of all geophysical data was carried out and drilling sites were selected. For each of the 4 sites, data bases were established using a Geographic Information System, and a detailed report was prepared synthesizing all information. In parallel, a call for tender specifying all requirements of the project was published in the Official Journal of the EC in April 2003. In June 2003, the interim Pollution Prevention and Safety Panel of IODP (iPPSP) provided a courtesy review for the Promess drilling sites. It recommended some additional seismic processing for better identification of gas anomalies. This was accomplished in July, 2003. In November 2003, following the detailed evaluation of the proposals submitted to Promess 1, Fugro Engineers B.V. was proposed as main sub-contractor for drilling and testing operation at sea. This was accepted by the EC on December 1st, 2003. The expected period for drilling operations is comprised between April and June, 2004, with SRV “Bavenit” operated by Fugro.

Relevance for society
▪ Promess will allow to better understand the effects of global and climate changes, sedimentary and oceanographic processes and tectonics on continental margins shaping.
▪ Promess will give access to a large and complementary data set that will allow further development for geophysical and geotechnical instrumentation.
▪ Promess will enable us to understand formation of sand bodies that can be of industrial interest for oil exploration or marine aggregates.
Promess future events
▪ Next Milestone: Promess cruise is to take place on Fugros’s « Bavenit » drilling ship before mid-2004
▪ Forthcoming presentations:
. US-Europe Eurostrataform annual meeting,
