You collect a sediment core on an expedition to the Aegean Sea. In this area, the background sedimentation rate is known to be between 0.01 cm per year. You also know that about 3600 years ago, the Santorini volcanic eruption dumped 1 meter of ash on the seafloor. The top of this ash layer is noticeable in the core about 36 cm down from top (seafloor surface). When processing the core, you see a funny signal in the 18O/16O ratio around 2 meters down the core.
Use the information above to estimate about how long ago the process that caused the funny signal occurred?
