Exploration of the Southeast U.S. Continental Margin

EX1806

Smear slide images and descriptions coming soon

NOAA expedition EX1806 sampled seafloor features in off of the southeast U.S. continental shelf using the submersible Deep Discoverer. OSU marine repository archives the rock samples collected during the expedition. Archived samples include fossil corals, mudstones, biogenic sediments and more. Below are the samples recovered from each dive.
