SWIR array deployed
17 October 2012
During a long night for the OBS team and the PI's of this mission, the sub-array of 8 ocean-bottom seismometers was successfully deployed on the Southwest Indian Ridge.
3:30 AM in the science lab.
The array of 8+1 instruments that we were deploying last night.
As a test for next year, our colleague Wayne Crawford had dropped an absolute pressure gauge close to one of the first array stations. After all eight seismometers had been deployed, the pressure gauge was called back to the surface around 5 AM. Two hours later, it was recovered using a small dinghy. The ship crew was able to safely lift the instrument up to the ship's deck. Today, the Marion Dufresne continues on its path along the ridge.
