About

Howdy!  I am currently a doctoral student in the oceanography department at the University of Delaware, studying under Dr. Art Trembanis in the Coastal Sediments Hydrodynamics and Engineering Laboratory (CSHEL).  My main research focus is geomorphology, or the study of earth’s surface processes.  Our lab uses robotic systems like autonomous underwater vehicles (AUVs) and drones, as well as sensors like sonar and LiDAR to study and map the seafloor and the coast (cartoon of various platforms and sensors below).

My dissertation has been focused on deciphering these enigmatic geomorphic features known as Carolina bays (a 3D print of some are shown in the top left picture).  These are round, rimmed, and sandy depressions found on the Atlantic Coastal Plain, which means they are on land, not in the ocean!  Carolina bays can be marshy or swampy or sometimes they can be drained and just collect water after it rains (sort of like a natural detention pond).  Here are several LiDAR images of some bays found in Delaware near Slaughter Beach, northern Kent County, and the eastern shore of Virginia:

 

Contrary to popular belief, these features are NOT impact scars of any kind (meteor, comet, or ice), they likely originated due to a combination of their poorly drained underlying sediment, intense winds, and after significant ponding of water, waves.  Carolina bay sediment deposits date between 120,000 years and within the last few thousand years, but sediment transport activity today seems to have ceased due to a lack of significant amounts of ponded water, less intense winds, and stabilization from vegetation.
