The coastal interface is shared by beachgoers, shorebirds, seals, and sharks - to name a few big players. It also happens to be a very dynamic place to be, especially during storms. One of the major goals of USGS coastal scientists is modeling total water levels and coastal change – these predictions rely on accurate mapping data. Over the past three years, the Woods Hole Coastal and Marine Science Center has led three major field efforts that map the coast and nearshore utilizing planes, kites, balloons, drones, boats, and cameras. The first, on Cape Cod, is a partnership with the National Park Service mapping offshore bars with stationary cameras and autonomous surface vehicles (ASVs). The second focused on Pea Island, NC, to try and capture the effects of a major storm from offshore to the dunes. And lastly, North Core Banks after Hurricane Florence (2018) and Hurricane Dorian (2019) where the USGS is monitoring the loss of about 18% of the subaerial volume of the island through the formation of over 80 erosional washout channels that have turned into rapidly disappearing ponds. 


Jin-Si Over is a geographer with the USGS - Woods Hole Coastal and Marine Science Center. A drone pilot and structure-from-motion specialist, she supports the Remote Sensing Coastal Change group and Aerial Imaging and Mapping group with GIS and surveying experience. She received her BSc at UNC-Wilmington, her MSc at the University of Victoria, and has worked with Rutgers University and the National Park Service on coastal monitoring/mapping prior to her current position with the USGS. In her spare time she forages for mushrooms and plays a lot of Wingspan.
