"The JOIDES (Joint Oceanographic Institutions for Deep Earth Sampling) Resolution is a seagoing research vessel that drills core samples and collects measurements from under the ocean floor, giving scientists a glimpse into Earth’s development. Data from the JR’s ocean drilling offer a scientific means of understanding climate and environmental change throughout a significant part of our planet’s history—a research subject often termed Earth’s paleoclimate. The JR’s core samples are the “smoking gun” in evaluating many historical events related to paleoclimate, changes in the solid earth and more — like the extinction of the dinosaurs and plate tectonics, for example."

Dr. Hemming is working with a group of scientists from Lamont Doherty Earth Observatory to take measurements to relate the sediment in the core to changes that happened in Earth’s past.
