Examining Fossil Coral

Caption

Georgia Tech associate professor Kim Cobb holds slabs of fossil coral taken from cores drilled in the Line Islands in the mid-Pacific Ocean. Powder from the slabs is examined in the mass spectrometer, which measures the ratio of oxygen isotopes to assess the strength of ENSO during the time the corals were growing.
