Summary of measurements

-Work done in the zone: The study zone lies between 13°20N and 16°N / 128°35W and 132°W.
-Detailed survey of an approximately 300 km2 sector, sidescan sonar, 3.5 kHz; Seabeam bathymetry.
-SAR surveys of 2 sectors sampled (3 hauls in all): 8 SAR dives between 5,000 and 6,000 m, distributed between NIXO 46 and NIXO 47 (making 164 hours in the water, of which 110 h of activities).
-Photos of bottom (1 track with Epaulard).
-Magnetism and gravimetry on short transits between zones.
-Data acquisition on seabed reflectivity.
-Sediment samples taken: by Küllenberg corer (23), by (TAAF) grab (11).
-Reconditioning of a met-ocean surface mooring.
- Work while underway: Seabeam bathymetry; gravimetry; magnetism.
-Note that part of the data collected during NIXO 47 is confidential.
