Coastal erosion rates along the Chukchi Sea coast near
ABSTRACT. Coastal cliff retreat along the Chukchi Sea coast from Barrow to Peard Bay is determined by comparison of 1949 and 1976 vertical arial photographs. Results indicate that the cliffed coast line had a mean long-term retreat rate of 0.31 m/yr. This retreat is considerably lower than that repo...
