Vegetated Coastal Dunes

IMG_6049

This work is ongoing, with Dr. Laura Moore of the Coastal Environmental Change Lab at UNC-Chapel Hill, and is focused on the yearly-to-decadal morphodynamics of vegetated coastal foredunes. My work spans both field and modeling efforts:

  • Field
    1. Use of a kite-mounted camera to capture the development of foredunes (both topography and vegetation) using the structure-from-motion software toolchain. Current work is focused on capturing a dataset to calibrate the Coastal Dune Model and making this work available as open data —See my figshare site to download raw images, digital surface models, composite orthoimagery, and ground control point coordinates. Previous work, done jointly with Amber Oliver (Undergraduate; Duke University class of 2016), focused on determining how the number of ground control points impacts digital surface model (vertical) error in the low slope, low relief coastal zone. Results were presented at the 2015 Geological Society of America meeting (Oliver et al., 2015) and published as a PeerJ Preprint (Goldstein et al., 2015). See our AGU field postcard from the 2015 summer season, and a blog post about our work from the UNC Science Writing and Communication Club website. Kite-based structure from motion is used to calibrate the coastal dune model.
    2. Field monitoring of topography and vegetation at two experimentally planted transects on Hog Island, Virginia, USA (at the Virginia Coast Reserve-Long Term Ecological Research Site). I am a collaborator on this work (deVries et al., submitted), which was done primarily by Elsemarie deVries (current Ph.D student; UNC-CH) and Theo Jass (M.S. 2015; UNC-CH).
