To assess coastal erosion dynamics during the 2018 and 2019 open water seasons at Drew Point, Beaufort Sea Coast, Alaska, we generated orthomosaic images and associated digital surface models from 9 unmanned aerial vehicle (UAV) surveys. UAV surveys were collected on 24 July 2018, 29 July 2018, 3 August 2018, 30 September 2018, 2 August 2019, 6 August 2019, 10 August 2019, 12 August 2019 and 15 August 2019. The digital surface models elevations are at relative sea level (2.2 meters (m) higher than local ellipsoid heights) and have been cleaned up (i.e. noise from waves removed) to only include the coast edge, ~125 m inland from the coast and toppled permafrost blocks in front of the bluff edge.
