Head Tretiak Kornylii R., Доктор технічних наук Registration Date 10-12-2025 Organization Lviv Polytechnic National University popup.description1 The main objective is to study the modern dynamics of the continental cryosphere and establish its relationship with changes in tropospheric parameters and spatial movements of the Antarctic crust based on independent processing of GNSS observations, satellite altimetry missions, and satellite radar interferometry to establish the relationship between the current spatial movements of the cryosphere and the Antarctic crust with the dynamics of the troposphere. popup.description2 The influence of changes in tropospheric parameters on the dynamics of the continental cryosphere and deformation of the Earth's crust was investigated. As a result of the work, radar images from Sentinel satellite missions in the Truz Glacier area for the period from 2015 to 2024 were processed, which made it possible to carry out spatial-temporal modelling of changes in the speed of movement of the Truz Glacier masses depending on the meteorological parameters of the troposphere; CryoSat satellite altimetry data for the Antarctic Peninsula for the period from 2011 to 2024 over the last 10 years were processed; the relationship between the parameters of changes in the continental ice cover based on satellite altimetry results and the parameters of the troposphere was established; ASAV GNSS station data (2021–2025) was analysed, taking into account the replacement of the antenna and receiver in March 2025, the vector of its displacements in the ITRF2014 system was determined, and the influence of seasonal fluctuations was established; the model of modern spatial deformations of the Earth's surface, performed at the geodynamic monitoring site of the Penola Strait – Lemaire Channel in the area of the Akademik Vernadsky research station, was refined, taking into account the cycle of GNSS observations performed in February–April 2025 during the 29th UAE; An assessment of the impact of non-tidal atmospheric and oceanic loads on the deformation of the Antarctic crust was performed based on data from permanent GNSS stations. These results contribute to a deeper understanding of the relationship between the cryosphere, Earth's crust and troposphere in the Antarctic region.
