CRUSTAL THICKNESS IN THE BAIKAL REGION AND MONGOLIA BASED ON INTERPRETATION OF THE SATELLITE GRAVITY MODEL

Геодинамика и тектонофизика
The article discusses deep Earth crustal structure in the Baikal region, neighboring territory and Mongolia. The EIGEN-6C4 satellite gravity model-based Moho depth map was drawn for the territory with coordinates 43 to 61° N, 88 to 120° E.

Subglacial Topography of Coats Land Records Post‐Gondwanan Landscape Evolution and Early Ice‐Sheet Behavior in East Antarctica

Journal of Geophysical Research: Earth Surface, Volume 131, Issue 2, February 2026.
Abstract The East Antarctic Ice Sheet (EAIS) formed circa 34 million years ago and now contains an ice volume equivalent to ∼52 m of global sea‐level rise. Although the EAIS is approximately in balance today, there is substantial uncertainty regarding the sensitivity of sectors underlain by low‐lying bed topography to future climate and ocean warming ...

Popigai and Chicxulub craters: multiple impacts and their associated grabens [PDF]

Solid Earth
More advanced data (gravity field model EIGEN 6C4 including the GOCE gradiometry data instead of EGM 2008) and a more sophisticated method (using a set of gravity aspects instead of gravity anomalies and the radial second derivative of the disturbing ...

A New Model of Quasigeoid for the Baltic Sea Area

Remote Sensing, 2021
The Space Research Centre in Warsaw is participating in the ESA project “Geodetic SAR for Height System Unification and Sea Level Research”. To observe the absolute sea level and enable the unification of the height systems, the physical heights of the ...

Deep Sources of Recent Volcanism in Armenia Inferred From Ambient Noise Tomography

Journal of Geophysical Research: Solid Earth, Volume 131, Issue 1, January 2026.
Abstract We perform Rayleigh wave ambient noise tomography to investigate crustal seismic velocity structure and sources of volcanism in Armenia. Armenia, a key part of the tectonically and volcanically active Caucasus‐Anatolia region, is actively being deformed by the ongoing Arabian‐Eurasian continental collision.

Multi‐Year Ice Dynamics at Køge Bugt Central Glacier Controlled by Bed Topography

Geophysical Research Letters, Volume 52, Issue 20, 28 October 2025.
Abstract Køge Bugt Central (KBC) is Greenland's fourth largest outlet glacier in terms of ice discharge. However, the drivers behind its substantial multi‐year variations in ice dynamics remain unknown. In this study, we use remotely sensed data sets of ice surface velocity, ice surface elevation, ice discharge, and terminus position, in combination ...

Evaluating the performance of various models for deriving orthometricheights using Global Navigation Satellite System (GNSS) data

Nova Geodesia
Orthometric heights are vital for fields such as topographic mapping, construction, engineering, and geophysical studies. This study examines the performance of five Global Geopotential Models (GGMs) and Global Navigation Satellite System (GNSS) data in

Unified Land–Ocean Quasi-Geoid Computation from Heterogeneous Data Sets Based on Radial Basis Functions

Remote Sensing, 2022
The determination of the land geoid and the marine geoid involves different data sets and calculation strategies. It is a hot issue at present to construct the unified land–ocean quasi-geoid by fusing multi-source data in coastal areas, which is of great

Calving Mechanisms Inferred From Observations of Surface Depressions at Helheim Glacier, Greenland

Journal of Geophysical Research: Earth Surface, Volume 130, Issue 10, October 2025.
Abstract Dynamical changes at the termini of tidewater glaciers may trigger sustained acceleration, thinning, and retreat, increasing a glacier's contribution to sea level rise. However, processes at the ice‐ocean interface occur across a range of spatial (cm to km) and temporal (minutes to years) scales, making these processes difficult to capture ...
