- Аннотация: Dynamics of the Winter Coast of the White Sea in the Intzy area was studied us-ing bathymetric and topographic maps (1833-1999), satellite imagery (1984-2016), measurements of the sea cliff crest (2009-2016) and echo sounding (2016). The average rate of retreat of the coastal ledge, cut out in the moraine hillside, for 185 years was 2.4 m / year. With the same speed the ledge has re-ceded also in 2009-2016. The area of the hill has decreased by 14.5%. Annual losses due to erosion and slumping of the coastal ledge are estimated at 0.32 ha. If the rate of destruction of the shore remains the same, the lighthouse of Intsy, located near the ledge, will be destroyed in 25 years. Key words: White Sea, Zimnij coast, morphodynamics, lithodynamics, monitor-ing, geomorphological safety.
