Important Message about LEARN NC

LEARN NC is evaluating its role in the current online education environment as it relates directly to the mission of UNC-Chapel Hill School of Education (UNC-CH SOE). We plan to look at our ability to facilitate the transmission of the best research coming out of UNC-CH SOE and other campus partners to support classroom teachers across North Carolina. We will begin by evaluating our existing faculty and student involvement with various NC public schools to determine what might be useful to share with you.

Don’t worry! The lesson plans, articles, and textbooks you use and love aren’t going away. They are simply being moved into the new LEARN NC Digital Archive. While we are moving away from a focus on publishing, we know it’s important that educators have access to these kinds of resources. These resources will be preserved on our website for the foreseeable future. That said, we’re directing our resources into our newest efforts, so we won’t be adding to the archive or updating its contents. This means that as the North Carolina Standard Course of Study changes in the future, we won’t be re-aligning resources. Our full-text and tag searches should make it possible for you to find exactly what you need, regardless of standards alignment.

Central section of Bogue inlet: sand bar without vegetation

Figure 2. Central section of Bogue inlet: sand bar without vegetation (Photograph by the author. More about the photograph)

Figure 2 is a photograph of Bear Island on the south side of Bogue Inlet taken from Bogue Bank, the land that appeared in the distance in figure 1. The dark object in the water is a sand bar formed by sediment that dropped from suspension as flooding tides slowed after passing through the most restricted section of the inlet. Predictably enough, this sand body is called the flood tide delta as it is the flood tide equivalent of the ebb tide delta outline by breakers in figure 1.

Note that there are no breakers here. That is because the flood tide delta is inside the inlet and is therefore not exposed to the full energy of ocean waves. Note also that the sandbar has no plants growing on it. The tidal currents are too strong and too frequent to allow plants to get a foothold here. If you look closely in the right background of the photo, however, you will see that salt marsh extends off the end of Bear Island where the flow of tidal currents is slower than in the center of the inlet.
