Impact of ice formations on the shore and bottom areas of shallow seas and large lakes of middle and subarctic latitudes
Ice formations affect linear and coastal structures not only in the Arctic, but also in the subarctic and middle latitudes. Most of the seas, lakes and bays, such as the Gulf of St. Lawrence, the Baltic, Black, Caspian Seas, and Sea of Japan, freeze partially or completely every year. Inland and nor...

Most of the seas, lakes and bays, such as the Gulf of St. Lawrence, the Baltic, Black, Caspian Seas, and Sea of Japan, freeze partially or completely every year.

A side-scan sonar survey and echo sounding, along with the diving surveys, are used to detect the ice scours/furrows on the bottom. To study the ice-exaration relief on the exposed bottoms, remote sensing data and materials obtained by means of unmanned aerial vehicles (UAV) are used, along with field surveys.

Ice formations affect linear and coastal structures not only in the Arctic, but also in the subarctic and middle latitudes. Most of the seas, lakes and bays, such as the Gulf of St. Lawrence, the Baltic, Black, Caspian Seas, and Sea of Japan, freeze partially or completely every year. Inland and northern lakes and seas of the Subarctic, such as the White Sea, the Gulf of Bothnia and the Sea of Okhotsk are characterized by the most severe ice conditions. Remote sensing methods are used to detect ice ridges and grounded hummocks. A side-scan sonar survey and echo sounding, along with the diving surveys, are used to detect the ice scours/furrows on the bottom.
