  1. 1. An Isostatic Earth Crustal Model : and Its Applications

    Författare :Mohammad Bagherbandi; Lars E. Sjöberg; Martinec Zdeněk; KTH; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Crustal thickness; inverse isostatic problem; isostasy; isostatic compensation; Moho depth; Moho density contrast; downward continuation; Earth sciences; Geovetenskap;

    Sammanfattning :  The Mohorovičič discontinuity (Moho), which is the surface separating the Earth’s crust from the mantle, is of great interest among geoscientists. The Moho depth can be determined by seismic and gravimetric methods. LÄS MER

  3. 2. Recovering Moho parameters using gravimetric and seismic data

    Författare :Majid Abrehdary; Lars E. Sjöberg; Mohammad Bagherbandi; Pavel Novák; KTH; []
    Nyckelord :crust; gravity; mantle; Moho depth; non-isostatic effect; residual isostatic topography; stripping; thermal state; Vening Meinesz-Moritz model; Geodesy and Geoinformatics; Geodesi och geoinformatik;

    Sammanfattning : Isostasy is a key concept in geoscience to interpret the state of mass balance between the Earth’s crust and mantle. There are four well-known isostatic models: the classical models of Airy/Heiskanen (A/H), Pratt/Hayford (P/H), and Vening Meinesz (VM) and the modern model of Vening Meinesz-Moritz (VMM). LÄS MER

  4. 3. Study on the Earth’s Surface Mass Variations using Satellite Gravimetry Observations

    Författare :Hadi Amin; Mohammad Bagherbandi; Lars Sjöberg; Faramarz Nilfouroushan; Martin Horwath; Högskolan i Gävle; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; geodetic reference system; geoid potential; global vertical datum; climate change; global warming; mass change; ice melting; sea-level change; remote sensing; satellite gravimetry; geodetiska referenssystem; geopotential; globala vertikala datum; klimatförändring; global uppvärmning; massförändring; issmältning; havsnivåförändring; fjärranalys; satellitgravimetri;

    Sammanfattning : Our complex planet is continuously undergoing temporal and spatial changes. In this context, ongoing processes in the Earth subsystems (geosphere, biosphere, cryosphere, hydrosphere, and atmosphere) cause changes in the gravity field of the Earth across a wide range of temporal and spatial scales.

  5. 4. Monitoring lithospheric motions by Satellite geodesy

    Författare :Nureldin A. A. Gido; Mohammad Bagherbandi; Lars E. Sjöberg; Faramarz Nilfouroushan; Hossein Nahavandchi; KTH; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Geodesi; Geodesy;

    Sammanfattning : Understanding of global and local Earth’s dynamic processes is of great importance to the Earth’s system knowledge, human life, and sustainability goals (e.g. climatic change and geo-hazard assessment, etc.). LÄS MER

  7. 5. Contributions of Satellite Geodesy to Post-Glacial Rebound Research

    Författare :Seyed Mehdi Shafiei Joud; Lars E. Sjöberg; Mohammad Bagherbandi; Martin Horwath; KTH; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Glacial Isostatic Adjustment GIA ; gravimetric GIA modelling; satellite geodesy; Gravity Recovery And Climate Experiment GRACE ; independent component analysis ICA ; Geodesy and Geoinformatics; Geodesi och geoinformatik;

    Sammanfattning : Glacial Isostatic Adjustment (GIA) is a global and long-term process in the Earth, which began 21.5 millennia ago, according to many ice history modellers. One way to understand the processes of the Earth’s interior, the crustal deformation, and a key correction to estimate the climatological parameters is obtained by studying GIA. LÄS MER
