Oceanic topography and heatflow: Indications for a silent discharge of cold rock into the convecting Earth

open access: yesGeophysical Research Letters, 1995
The 2.5 km mean relative elevation of mid ocean ridges is arguably consistent with a steady state thickness of ≈100 km for the oceanic lithosphere. Here we explore some consequences of this particular value. Based on seismic models of the uppermost oceanic mantle, we infer that no significant heat is added to normal asthenosphere following accretion at

Solvation Entropy as a Lever for Steering the Macroscopic Properties of a Functional Supramolecular Helical Polymer. [PDF]

open access: yesAngew Chem Int Ed Engl
The structural transition between the two fully‐characterized states of a supramolecular helical hydrogen‐bonded polymer (represented as blue and light pink stacks) can be predictably varied over 85 K by changing the nature and amount of cosolvent; entropy of solvation (schematized as solvents of different sizes) is the main lever to tune the ...

Geophysics Appearance of The South China Sea

open access: yesIndonesian Journal of Applied Physics, 2021
South China Sea (SCS) is underlain by sediments of an average density 2.10 g/cm3 of 2 km thickness at its central part up to 10 km in the margins. The basement rock is the upper and lower crust of densities 2.67 and 2.85 g/cm3 respectively of varying ...

Martian Mantle Heat Flow Estimate From the Lack of Lithospheric Flexure in the South Pole of Mars: Implications for Planetary Evolution and Basal Melting

open access: yesGeophysical Research Letters, 2021
Heat flow measurements are important for our understanding of planetary interior composition, structure, and evolution. In the absence of direct measurement, a first‐order estimate of a planet's interior heat flow can be made by modeling the lithosphere ...

Heat-Flow Coupling Law for Freezing a Pipe Reinforcement with Varying Curvatures

open access: yesApplied Sciences, 2023
Using the temperature and seepage field-coupling module within COMSOL Multiphysics software, we examined freezing behavior and its evolving patterns in curved underground freezing pipes.

Porewater Geochemical Assessment of Seismic Indications for Gas Hydrate Presence and Absence: Mahia Slope, East of New Zealand’s North Island

open access: yesEnergies, 2022
We compare sediment vertical methane flux off the Mahia Peninsula, on the Hikurangi Margin, east of New Zealand’s North Island, with a combination of geochemical, multichannel seismic and sub-bottom profiler data.

Hydrothermal Activity at a Cretaceous Seamount, Canary Archipelago, Caused by Rejuvenated Volcanism

open access: yesFrontiers in Marine Science, 2020
Our knowledge of venting at intraplate seamounts is limited. Almost nothing is known about past hydrothermal activity at seamounts, because indicators are soon blanketed by sediment.
