Short summary
The architecture, formation, and modification of oceanic plates are fundamental to our of understanding key geologic processes of the Earth. Geophysical surveys were conducted around a site near the Hawaiian Islands (northeastern Hawaiian North Arch region). This workshop report describes scientific targets for 2 km deep ocean drilling in the Hawaiian North Arch region in order to provide information about the lower crust from unrecovered age and spreading rate gaps in previous ocean drillings.
