Discovering the Deep: Exploring Remote Pacific Marine Protected Areas

EX1703

NOAA expedition EX1703 sampled seamounts and seafloor features in the deep waters of the Howland and Baker Unit of the Pacific Remote Islands Marine National Monument (PRIMNM), American Samoa, the Phoenix Islands Protected Area (PIPA), and the waters around New Zealand’s Territory of Tokelau using the submersible Deep Discoverer. OSU marine repository archives the rock samples collected during the expedition. Archived samples include basalts and fossil corals. Below are the samples recovered from each dive.
