The effective elastic thickness of the India Plate from receiver function imaging, gravity anomalies and thermomechanical modelling [PDF]
, 2006 The range and the meaning of the effective elastic thickness (EET) in continental areas have been subject to controversy over the last two decades. Here we take advantage of the new data set from the Hi-CLIMB seismological experiment to re-estimate the ...

Earth and Space Science, 2023 Gravity inversions have contributed greatly to our knowledge of the interior of planetary bodies and the processes that shaped them. However, previous global gravity inversion methods neglect the inference of mantle density anomalies when using ...

No conformal anomaly in unimodular gravity [PDF]
Physical Review D, 2013 The conformal invariance of unimodular gravity survives quantum corrections, even in the presence of conformal matter. Unimodular gravity can actually be understood as a certain truncation of the full Einstein-Hilbert theory, where in the Einstein frame the metric tensor enjoys unit determinant.

Anomalies in covariant W-gravity
Physics Letters B, 1991 Abstract We consider free scalar matter covariantly coupled to background W-gravity. Expanding to second order in the W-gravity fields, we study the appropriate anomalous Ward-Takahashi identities and find the counterterms which maintain diffeomorphism invariance and its W-analogue. We see that a redefinition of the vielbein transformation rule under

Morphology and tectonics of the Mid-Atlantic Ridge, 7°–12°S [PDF]
, 2003 We present swath bathymetric, gravity, and magnetic data from the Mid-Atlantic Ridge between the Ascension and the Bode Verde fracture zones, where significant ridge–hot spot interaction has been inferred.

Application of Radial Basis Functions for Height Datum Unification
Geosciences, 2018 Local gravity field modelling demands high-quality gravity data as well as an appropriate mathematical model. Particularly in coastal areas, there may be different types of gravity observations available, for instance, terrestrial, aerial, marine gravity,

Gravity Anomalies in the Galpagos Islands Area [PDF]
Science, 1974 In a recent report Case et al. (1) presented a free-air gravity anomaly map of the Galapagos Islands based on 32 gravity stations on the islands. On the basis of their data they stated that the Galapagos Islands are associated with an east-west trending "residual negative anomaly" which is superimposed on a "broader positive anomaly of unknown ...
