Cruise period1988-10-13 — 1988-11-17
Port of departurePapeete, French Polynesia
Port of returnValparaiso, Chile
Objectives1. To run GLORIA over a well defined micro-plate, imaging as much of the plate as possible.
2. Thus to completely determine the position and nature of the present microplate boundaries.
3. To determine as far as possible the tectonic history of the microplate from its inception to the present.
4. To digitally combine GLORIA, SeaBeam and SeaMARC II data to provide for the first time a combined topographic and sidescan image of a tectonic plate.
5. On passage to the microplate, to obtain GLORIA and other data relevant to the tectonic history of the region, and particulary to improve knowledge of the distribution of fracture zones and volcanic chains between Tahiti and the Easter microplate.
6. On passage from the microplate, to obtain GLORIA and other data relevant to the tectonic history of the region; particularly to determine the precise position and azimuth of the Chile transform fault, and thus to improve the precision of the Nazca-Antarctic rotation pole.
