Climate change has affected the North Carolina coastal environments and coastal hazards have already taken place in that area. Significant adverse impacts in the form of frequent storms and higher rates of beach erosion have been registered, thus, making compelling the necessity of a current understanding of the vulnerability of coastal zones. We propose to study this vulnerability in the Duck area, North Carolina (location: Lat 36 10 57” N Long 75 45 05” W) utilizing the work of the Army Corps of Engineers at Duck, North Carolina at the Field Research facility (FRF). Our interest in their work lies on the use of video imagery based techniques (researched, designed, experimented and developed by the Coastal Imaging Lab of Oregon State University) implemented for the capture and understanding of changes of near shore morphology since beaches are continuously changing from geological materials (sands, dead and/or bleached corals…etc) shifted by waves, tides, and currents moving sediments and eroding shorelines; this phenomenon carries very challenging, above all devastating outcomes on coastal communities. We are most interested in the intolerant and dramatic periods of storms and hurricanes (when sediment transport is more energetic [Stockdon and Holman,2000] and shoreline changes are more rapid) associated with extended cloud cover when satellite fails to produce images of events occurring during those times.
Due to proprietary rights to this technique developed by CIL, and other limitations, we could at this time acquire neither all the scientific details related to the techniques implemented by the Coastal Imaging Lab (CIL) of Oregon State University nor the logistics behind the installation of the outlet at the FRF tower; nonetheless, our study outcome will help demonstrate the relevance and the ability of the video imagery based techniques to collect images of coastal not only during times of rebuilding but also above all, during dramatic periods of long lasting impact of storms and hurricanes.

One of the methods we observed them using to collect data is a sled. This is a flat trapezoidal shaped wave data collector.
This type of shape allows it to stay stationary when collecting data, while also versatile when it is time to move it
