Observational estimates of dynamic topography through space and time

M Hoggard, J Austermann, C Randel… - Mantle convection …, 2021 - Wiley Online Library
Earth's mantle undergoes convection on million‐year timescales as heat is transferred from
depth to the surface. While this flow has long been linked to the large‐scale horizontal forces …

A 35-million-year record of seawater stable Sr isotopes reveals a fluctuating global carbon cycle

A Paytan, EM Griffith, A Eisenhauer, MP Hain… - Science, 2021 - science.org
Changes in the concentration and isotopic composition of the major constituents in seawater

Carbonate weathering, CO2 redistribution, and Neogene CCD and pCO2 evolution

LA Derry - Earth and Planetary Science Letters, 2022 - Elsevier
The carbonate compensation depth (CCD), δ 13 C of marine carbonate, atmospheric pCO 2
and major ion composition of seawater provide constraints on how geological carbon cycle …

Reduced continental weathering and marine calcification linked to late Neogene decline in atmospheric CO2

W Si, Y Rosenthal - Nature Geoscience, 2019 - nature.com

Earth's isostatic and dynamic topography—A critical perspective

AM Forte, DB Rowley - Geochemistry, Geophysics, Geosystems, 2022 - Wiley Online Library
Earth's topography arises from the linear superposition of isostatic and dynamic
contributions. The isostatic contribution reflects the distribution of thickness and density of …
