Major cruise results
1-2 page description of cruise results for general public access
The main target of the multichannel CASIS 2 cruise was to study the deep stcture beneath the Magdalena deep sea fan off Colombia. Indeed we knew that the major oil companies and particularly ELF, were interested in this area. We wanted obtain a deep information in this region and complete our knowledge by the regional surveys performed by the oil companies and also obtain a financial support for our studies. However, we cannot obtain the clearances to work in the economic waters of Colombia, probably due to a misunderstanding. We have to wait during several days on the Nicaragua Rise and we carry out a survey of this region then the cruise was stopped the 17/02/99 whereas the campaign was performed to finish at the end of the month. After a DEA on the survey done on the Nicaragua Rise E. D’Acremont quit this work and switched to another subject in the Aden region. Moreover, the project to drill a well in the Magdalena deep sea fan has been cancelled by ELF. The multichannel seismic lines performed during the shortened CASIS 2 survey have a good quality. The contact between the volcanic basement of the Venezuela Basin and the Aves Ridge that is a remnant arc located west of the Present Lesser Antilles volcanic arc has been documented. On the Nicaragua Rise a recent extensional tectonics has been evidenced and mapped..
All the seismic data in our access (mainly American and French) in the Caribbean Basin have been digitized with the main horizons (A” and B”). We proposed to give these data with the addition of the CASIS 2 data to IFP to perform a depth to basement map for the international project CGGM to publish maps of the Caribbean region.
