Furthermore, time-dependent experiments are performed and the SHM system is calibrated over time through Bayesian Model Updating...

... strength conducted in 2019-2020 in the Khatanga Bay of the Laptev Sea. It is shown that there is no significant difference between level ice and deformed ice (consolidated layer of ice hummocks) in terms of the strength/temperature dependence. Furthermore one-year level ice and two-year level ice, as well...

... ABSTRACT The article presents analytical dependencies for calculating the water resistance force acting on a non-tabular iceberg under tow, that depend on geometric dimensions of the iceberg and the speed of it's movement. During 2016-2017 iceberg towing trials in the Barents and Kara Seas 15...

... of the strength distribution of the consolidated layer were constructed for the entire life cycle of the ice formation; these maps were constructed based on the thermal history of the hummock and obtained dependence of the local strength on the ice temperature. The thermal state of the hummock is fundamentally...
