| Cruise identifier | ANTITHESIS 1 |
| Cruise period | 2013-11-23 — 2013-12-24 |
| Status | Completed |
| Port of departure | Pointe-à-Pitre, Guadeloupe |
| Port of return | Pointe-à-Pitre, Guadeloupe |
| Purpose | Research |
| Objectives | This project presents a study of the seismogenic potential of the Antilles subduction zone. The acquisition of deep reflection and wide-angle seismic data together with heat flow measurements, gravimetric and magnetic anomalies will help answer scientific questions about the geometry and characteristics of the subduction channel and the deep structure of the margin. The project also aims at recording seismic activity, bathymetry and whale sounds using the hydrophones included in the bottom seismometers.
Data acquisitions and analyses carried out during the Antithesis cruise are essential to evaluate the seismogenic potential of the Northern Segment of the Lesser Antilles margin. Seismic data will be acquired onboard vessel Atalante during the first leg. Heat-flow data will be acquired onboard vessel Pourquoi Pas? During the second leg. |
