Seafloor Changes

Caption

The amount of seafloor exhibiting small structural anomalies is plotted as a function of the age of seafloor. Trends that persist over 10 million years have been subtracted to highlight transient features, and only high spreading rates are plotted here. The highest peak, which indicates the production of 8 percent more anomalous seafloor than on average, occurs at 66 million years ago and is coincident with the age of the Chicxulub meteorite impact.
