On The Rocks


By Sophie Alexander

My video is based on my Phd research. I am attempting to constrain changes in ocean circulation 50 million years ago. To do so, I use fish tooth neodymium measurements. My video explains how fish teeth are preserved on the seafloor, gain a neodymium signature and can be used to track circulation changes.
