This study presents 25 years of carefully processed gravity measurements from western France, offering a unique dataset to support investigations of long-term land motion and sea level change. The data are consistent with satellite-based observations and are made available for use in future geophysical and climate-related research.

The precise geometry and extent of Atlantic circulation changes that accompanied rapid climate changes of the last glacial period are still unknown. Here, we combine carbon isotopic records from 18 Atlantic sediment cores with numerical simulations and decompose the carbon isotopic change across a cold-to-warm transition into remineralization and circulation components. Our results show that the replacement of southern-sourced by northern-sourced water plays a dominant role below ~ 3000 m depth.
