Stratigraphic method of eustatic quantifications: a sea level curve based on Jurassic-Cretaceous strata of the Russian Platform [PDF]
, 1993 Two types of sea level are presently defined: relative and eustatic. Relative sea level (RSL) is the sea surface elevation relative to some local land surface.

Ocean dynamics of outer solar system satellites
, 2019 Ocean worlds are prevalent in the solar system. Focusing on Enceladus, Titan, Europa, and Ganymede, I use rotating convection theory and numerical simulations to predict ocean currents and the potential for ice-ocean coupling.

Ancient Mars Climate With a Polar Ocean and Ice Sheet Dynamics
Journal of Geophysical Research: Planets, Volume 130, Issue 10, October 2025.Abstract In this article, we study the conditions required to maintain a stable ocean on Mars 3 Ga using a new suite of simulations. These simulations couple a 3D Global Climate Model with ocean dynamics and ice sheet flow. The model includes the main processes of the atmosphere/hydrosphere/cryosphere to investigate Mars' ancient climate.

Isostatic response of the lithosphere beneath the Mozambique Ridge (SW Indian Ocean) and geodynamic implications [PDF]
, 1989 International audienceS U M M A R Y The SW Indian Ocean is characterized by the presence of several aseismic features. The Mozambique Ridge, an elongated feature lying roughly parallel to the SE coast of Africa, is by far the least known of those ...

Tectonics, Volume 44, Issue 10, October 2025.Abstract Inception of obduction is a rare phenomenon in the Wilson cycle and requires specific prerequisites to transfer relatively high‐density oceanic lithosphere over the less‐dense continental lithosphere. The world's famous Semail ophiolite belt developed during the Late Cretaceous, when Neo‐Tethyan oceanic lithosphere obducted onto the rifted ...

Comparisons of global topographic/isostatic models to the Earth's observed gravity field [PDF]
The Earth's gravitational potential, as described by a spherical harmonic expansion to degree 180, was compared to the potential implied by the topography and its isostatic compensation using five different hypothesis.

Evidence for an Early Formation of Serenitatis Basin at 4.25 Ga Shifts Lunar Chronology
Geophysical Research Letters, Volume 52, Issue 18, 28 September 2025.Abstract Troctolite sample 76535, collected in Serenitatis basin during Apollo 17, formed at least 50 km deep, experienced maximum shock pressures of 6 GPa, and has a 40Ar/39Ar excavation age of 4.25 Ga. Previous work attributed 76535 to the South Pole‐Aitken (SPA) basin, presumably dating the SPA‐impact and constraining lunar bombardment history. Here

Dynamic compensation in the central Pacific Ocean [PDF]
The intermediate-wavelength geoid (lambda similar to 2000 km) and sea-floor topography fields in the central Pacific Ocean were studied in terms of static and dynamic compensation models.

Impact of GRM: New evidence from the Soviet Union [PDF]
Gravity information released by the Soviet Union allows the quantitative assessment of how the geopotential research mission (GRM) mission might effect the ability to use global gravity data for continental tectonic interpretation.

Adjoint models of mantle convection with seismic, plate motion, and stratigraphic constraints: North America since the Late Cretaceous [PDF]
, 2009 We apply adjoint models of mantle convection to North America since the Late Cretaceous. The present-day mantle structure is constrained by seismic tomography and the time-dependent evolution by plate motions and stratigraphic data (paleoshorelines ...
