A small, feathered theropod dinosaur, Saurornitholestes langstoni was long thought to be so closely related to Velociraptor mongoliensis that some researchers called it Velociraptor langstoni—until now. Credit: Jan Sovak.

A new study led by Yale University confirms a long-held theory about the last great mass extinction event in history and how it affected Earth's oceans. The findings may also answer questions about how marine life eventually recovered. Credit: Michael Henehan & Pincelli Hull

Mystery solved: Ocean acidity in the last mass extinction

The Ice Drilling Design and Operations (IDDO) group at the University of Wisconsin-Madison designed and built the South Pole Ice Core (SPICE) drilling system, called the Intermediate Depth Drill. Based on a Danish drill called the Hans-Taunsen drill, the Intermediate Depth Drill was purpose-built for coring 1,500 meters of ice. The ice cores collected at this depth (from the South Pole) contain atmospheric gases from the past 40,000 years, the time of transition from the last ice age to the present warm climate.
