Morphometric Features of the Submarine Slope of the Southwestern Part of Valaam Island

详细

A digital bathymetric model with a 10 × 10 m spatial resolution was created on the basis of the depth sounding on the southwestern slope of Valaam Island with the use of an echo sounder combined with a side-scanning sonar and satellite navigation system. Bottom slopes with 60-degree value, where there are rock structures barely overlapped by recent bottom deposits, were registered. Large boulders and slide rocks, which can cause underwater noise in sliding down along steep slopes, were revealed.
