The main objective of our core sampling was to characterize the eruptive history of Montserrat back to the early beginnings of this island (~2.6 million years ago), based on the marine sediments and tephra (pyroclastic deposits from explosive volcanism) layers cored at this site. During week 2 of Expedition 340 we finished our drilling operations around the island of Montserrat.
