Chilean president Michelle Bachelet visited the R/V Marcus G. Langseth on Jan. 9 when it docked at the port city of Valparaiso, touring the ship—which is operated by Columbia’s Lamont-Doherty Earth Observatory--on its months-long voyage to map the occurrences of earthquakes and tsunamis in the region.
The Lamont-Doherty Core Repository holds one of the world’s most unique and important collections of scientific samples from the deep sea—approximately 72,000 meters of sediment cores from every major ocean and sea.
