Windows to the Deep 2019: Exploration of the Deep-Sea Habitats of the Southeastern United States 

EX1903L2

NOAA expedition EX1903 Leg 2 sampled marine geologic features in the deep waters off of the Southeastern United States using the submersible Deep Discoverer. OSU marine repository archives the rock samples collected during the expedition. Archived samples include carbonate and ferromanganese rocks. Below are the samples recovered from each dive.
