Morphometric Parameters of Stamukhas in the Laptev Sea

摘要

The article presents the results of an analysis of the expedition data on morphometry and internal structure of stamukhas, investigated in spring 2017 in the southwestern part of the Laptev Sea. Using a thermal drilling method, researchers obtained average and extreme values of all measured parameters and made an approximation by theoretical distribution functions. Analysis of sonar and tachometric survey data shows the average values of stamukha volume/mass to be more than five times greater than the average values of ice ridge volume/mass. The maximum duration of the recorded stamukhas' drift was thirty days.
