Ishinomaki - Before and After
A massive earthquake, and subsequent tsunami, struck the northeast coast of Japan on Friday, March 11, 2011. The USGS calculated the magnitude of the earthquake as a 9.0, the fourth largest ever recorded. The tsunami that followed was over 10 meters high in places.

Pallid Sturgeon Surgery
An incision just big enough to fit the transmitter is made in the belly of the sturgeon and a few stitches close it up. The stitches eventually dissolve but a small scar remains visible.
