OBS deployment will start soon...

Nine days after the departure at Honolulu, we are finally arriving at our survey area. In about an hour, we will start deploying ocean bottom seismometers, 28 in total. Will Sager noted me that this transit was like biking across the United States. A very good analogy indeed, as we've been sailing at 10-11 knots (which is about 12 miles per hour). See the map above to feel the scale. You can also see that the Shatsky Rise is about the same size of California. We'll be spending the next 32 days to study this massive volcanic feature by active-source seismology.
