Campaign: PRISME

The PRISME cruise objectives were to: - quantify the risk of earthquake-induced sedimentary liquefaction (for areas studied on the Algerian margin and slope off Nice, France); - quantify the risk of instability and failure due to loss of resistance in sensitive clay (slope off Nice); - quantify the risk of slope breaks and erosion caused by bottom currents (canyon heads - gulf of Lion); - identify the triggering factors for slides seen off Ibiza; - and begin to identify the turbidity related to seismic activity along the Algerian margin. This falls under the ANR-Isis an dGDR Marges projects. The cruise took place on 5 sites: Site 1A - Gulf of Lion - North: N 42° 50.00' South: N 42° 40.00' West: E 003° 35.00' East: E 004° 0.00' / Site 2B - Ibiza channel - North: N 38° 39.00' South: N 38° 37.50' West: E 000° 47.00' East: E 000° 51.00' / Site 3A - Alger - North: N 37° 30.00' South: N 36° 40.00' West: E 002° 00.00' East: E 004° 00.00' / Site 3B - Djijel North: N 37° 30.00' South: N 37° 00.00' West: E 005° 00.00' East: E 004° 00.00' / Site 4A - Djijel North: N 43° 40.00' South: N 43° 38.00' West: E 007° 12.00' East: E 007° 15.00'.
