The constant monitoring of dangerous marine phenomena in harbor bays and in other coastal areas is of great scientific interest and has a pronounced applied nature. First of all, this is connected with ensuring security in the zones of maritime activities.
The instruments available at the SDB MRAT FEB RAS meet international standards, and the specialists of the Institute have extensive experience in conducting experimental studies, as well as processing the data obtained using modern methods and physical interpretation of the results obtained.
Since 2009 SDB MRAT experts have been continuously measuring sea level fluctuations off the southern coasts of Sakhalin Island in the Aniva and Mordvinova Gulfs, as well as in the depth of the water area on the western and eastern coasts (Novikovo and Kirillovo settlements). From 2011 to the present, work is being done in the area of Cape Svobodny on the south-eastern coast of Sakhalin Island. During the work at Cape Svobodny, sea level measurements were made by bottom sensors at a depth of 16 m below the sea surface. According to the results of observations, about 200 waves were recorded, which satisfy the amplitude criterion of killer waves (the height of anomalous waves is twice the height of significant waves).
For example, two abnormally large waves up to 6 meters in height were recorded on December 24 and 25, 2011, during the cyclone movement. During the passage of this cyclone on 18 December 2011 in the central part of the Sea of Okhotsk 200 km from Sakhalin, the floating drilling platform “Kola” was wrecked.
