Arctic coastal erosion is a widespread phenomenon affecting both coastal ecosystems and engineering infrastructure. In the last decades, a lot of new data on coastal erosion rates appeared, as along with new methods and approaches to their studies. The most valuable are long-term series of field observations of coastal dynamics in remote sites. This study presents new detailed data on coastal erosion within a coastal segment at Lorino community, Chukotka Autonomous Okrug, Russia. Previously published studies cover the period of 1967-2017. We updated the existing time series with the data for 2018-2021 summer seasons using an UAV. The obtained raw data was processed in Agisoft Photoscan software and compared with previous coastal positions. Moreover, available Corona satellite imagery allowed to reconstruct erosional bluff position in 1963, considerably expanding the timeseries backwards. The obtained coastal erosion rates were compared with wind energy potential values calculated for every open water period. Both characteristics show good correlation that provides an opportunity to calculate the expected coastal erosion rates and develop mitigation strategies for the coastal community of Lorino. This study has been supported by the RSF 22-77-10031 project “Coasts of the Russian Arctic seas: past, present, future”.
