Bipolar Seesaw of Atmospheric CO2 Between North Pacific and Southern Ocean at Millennial Timescales
Geophysical Research Letters, Volume 52, Issue 13, 16 July 2025.Abstract The interhemispheric relation of deep‐water ventilation and surface‐ocean productivity may have played a prominent role in past atmospheric CO2 regulation. However, how these processes vary on orbital‐millennial timescales remains poorly understood.

Tephrochronology: principles, functioning, application [PDF]
, 2011 Tephrochronology is a unique method for linking and dating geological, palaeoecological, palaeoclimatic or archaeological sequences or events. The method relies firstly and fundamentally on stratigraphy and the law of superposition, which apply in any ...

Cryptotephra from a ~120 ka Tondano eruption in a sediment core from Lake Towuti (Indonesia)
Journal of Quaternary Science, Volume 40, Issue 5, Page 741-746, July 2025.ABSTRACT Southeast Asia is one of the most volcanically active regions in the world, yet their long‐term eruptive history has been comparatively little studied. In particular, little work has explored the potential of sedimentary archives to record distal cryptotephra, which may help in identifying some of the region's larger Quaternary eruptions. Here,

Far‐travelled ash in past and future eruptions: combining tephrochronology with volcanic studies
Journal of Quaternary Science, 2019 Studies of recent eruptions have improved our understanding of volcanic ash transport and deposition, but have also raised important questions about the behaviour of far‐travelled (distal) volcanic ash.
