Then, on September 27, 2017, the researchers announced the results of their expedition. For two months, the team had traveled the Pacific Ocean on board JOIDES Resolution, a drilling ship operated by the IODP. And over the course of the study, they visited six separate sites across Zealandia.
While at each site, researchers drilled down into the seabed to collect samples from the continent’s crust. At points, they had to descend through almost 16,000 feet of ocean to reach the bottom. Then, once there, they continued to drill to a depth of some 8,200 feet.
