Sediment

Caption

Sediment samples in the lab of Richard Norris obtained by the Ocean Drilling Program reveal the mark of "hyperthermals," warming events lasting thousands of years that changed the composition of the sediment and its color. The packaged sediment sample on the left contains sediment formed in the wake of a 55-million-year-old warming event and the sample on the right is sediment from a later era after global temperatures stabilized.
