The Institute for the Environment (IE) class is learning about coastal geology this week by experiencing it first hand. Walther’s Law tells us that the vertical succession of facies reflects lateral changes in environment. That concept is an important part of the coastal geology foundation and we learned how to apply it by collecting a vibracore from an old flood-tidal delta deposit that was active 1800 AD. The old flood-tidal delta is part of Bogue Banks, NC and is located just across the sound from IMS. The IE class brilliantly identified sediments deposited in the salt marsh, flood-tidal delta, and Bogue Sound environments, all stacked on top of each other and sampled in our core.
