Ocean drilling expedition retrieves multi- million-year cores from the North Atlantic off Newfoundland. Researchers on board the scientific ocean drilling vessel JOIDES Resolution recently completed an expedition to the North Atlantic, near the coast of Newfoundland, Canada. Here, near the final resting place of the ill-fated RMS Titanic, large sediment drifts contain detailed records of the Paleogene – a span of about 40 million years when Earth’s climate shifted from a sultry “hothouse” to a cooler climate, featuring the first polar ice sheets.
