Deploying an ocean bottom seismometer sinks into the Pacific

Deployment of an ocean bottom seismic instrument off the fan-tail of the R/V Kilo Moana in the central Pacific Ocean. Once released, this instrument will spend the next two hours sinking to the bottom of the ocean, where it will deploy a seismometer sensitive enough to detect earthquakes on the other side of the world. It will record data for 15 months before we call it back to the surface to recover it (with the assistance of the red flag on top!)
