Objective	The GEODEVA cruise was part of a land/sea geodesics project at Vanuatu, one of whose objectives is to characterize the crustal deformation associated with seismic cycles. The work carried out to study vertical underwater movements included: readings recovered from immersed tide gauges and markers set up were reoccupied, sea level measurements taken using GPS. Surveying to install a mast for GPS measurements the convergence between Sabine Bank (Australian plate) and Santo (Vanuatu). The related programs are: MOTEVAS, GEODEVA and ARC-VANUATU.

Summary of measurements

-2 tide gauges set up on high stands of 2 distinct plates (Wusi and Sabine banks).
-Pressure measurements on 2 geodesic markers set up in the Baie des Tortues (Sarami, bay to the east of Santo).
-GPS sea level measurements using a GPS buoy and a receiver installed aboard RV Alis.
-GPS waypoint on land at NWST: North-west Santo (near village of Olpoi).
