Gravity‐Derived Antarctic Crustal Thickness Based on the Gauss‐FFT Method

Geochemistry, Geophysics, Geosystems, 2022
The information on crustal thickness in Antarctica can provide significant constraints on its crustal deformation and tectonic evolution. To generate reliable images of crustal features, we investigate the model of Moho depth and crustal thickness ...

IODP Expedition 310 Reconstructs Sea Level, Climatic, and Environmental Changes in the South Pacific during the Last Deglaciation [PDF]

Scientific Drilling, 2007
The timing and course of the last deglaciation (19,000–6,000 years BP) are essential components for understanding　the dynamics of large ice sheets (Lindstrom and MacAyeal,　1993) and their effects on Earth’s isostasy (Nakada and　Lambeck, 1989; Lambeck ...

Integrating Gravity and Surface Elevation With Magnetic Data: Mapping the Curie Temperature Beneath the British Isles and Surrounding Areas

Frontiers in Earth Science, 2018
In this work, we study the lithospheric structure of the British Isles using a methodology that allows for forward modeling of the Curie temperature depth based on seismic, elevation and gravity observations within an integrated geophysical-petrological ...

Quantification of Erosion and Uplift in a Rising Orogen—A Large-Scale Perspective (Late Tortonian to Present): The Case of the Gibraltar Arc, Betic Cordillera, Southern Spain

Remote Sensing, 2020
The present study deals with the morphometric quantification of erosion and illustrates the uplift component triggered by denudation (isostasy) in the growth and evolution of a rising orogeny by the application of Airy isostasy concepts.

On the More Complex Wavelength Dependency of Airy Isostasy in Icy Shells of Ocean Worlds

Geophysical Research Letters, 2023
The topography of ocean worlds is often used to infer ice shell thicknesses by assuming topography is compensated by a basal root. We systematically test the stability of isostatically compensated topography in ice shells. At short horizontal wavelengths,

Analysis of Different Methodologies to Calculate Bouguer Gravity Anomalies in the Argentine Continental Margin [PDF]

, 2014
We have tested and used two methods to determine the Bouguer gravity anomaly in the area of the Argentine continental margin. The first method employs the relationship between the topography and gravity anomaly in the Fourier transform domain using ...

Rheology of the Indian and Tarim plates in the Karakoram continent-to-continent collision zone

Annals of Geophysics, 1997
Bouguer gravity anomalies in the region of Western Himalayas, Karakoram and Tien Shan show large negative values, but classical isostatic models are insufficient to account for the detailed pattern of the observed anomalies.

Modeling postbreakup landscape development and denudational history across the southeast African (Drakensberg Escarpment) margin [PDF]

, 2002
We employ a numerical surface processes model to study the controls on postbreakup landscape development and denudational history of the southeast African margin.

Spatial-Temporal Comparison of Distribution of Seismic Activity and Isostatic Anomalies along the Mid-Atlantic Ridge

Вестник Камчатской региональной ассоциации "Учебно-научный центр". Серия: Науки о Земле, 2019
The structure of a spatial-temporal distribution of seismic activity along the Mid-Atlantic Ridge (MAR) according to teleseismic data is characterized by areas of increased activity that are marked on spatial-temporal cross-sections with stripes of event

Weichselian history of the Fennoscandian Ice Sheet centre, Kvarken archipelago, western Finland—flow shifts, thermal regime and deglaciation

Boreas, EarlyView.
Rapid thaw of the Earth's cryosphere in response to anthropogenic warming highlights the need to identify and understand the contrasting signatures of past ice‐sheet stability and collapse. The Kvarken archipelago, western Finland, at the centre of the former Fennoscandian Ice Sheet (FIS), has been designated a UNESCO World Heritage site in recognition
