Hawaii Scientific Drilling Project

Drilling and coring into Mauna Kea and Mauna Loa volcanoes, the Hawaii Scientific Drilling Project (HSDP) obtained the deepest core samples from a Hawaiian volcano and set records for deep continuous coring. The recovered rock samples were perhaps the longest continuous stratigraphic record from any ocean island volcano. This international project revealed the geochemical and geophysical processes within mantle plumes that form “mid-plate” volcanoes. The project results answer questions about oceanic volcanoes, mantle plumes, and ocean island water resources, but raise many more.
