Shelf-edge deglacial reef establishment and subsequent partial demise: Response to distinct pulses of sea-level rise associated with environmental changes
Autor: Brandon B. Harper, André W. Droxler, Jody M. Webster, Paolo Montagna, Yusuke Yokoyama, Marc Humblet, Stéphan J. Jorry, Luc Beaufort, Kazuyo Tachikawa, Edouard Bard, Edwige Pons-Branchu
Publikováno v: Coral Reefs and Sea-Level Change: Quaternary Records and Modelling. :141-171
The partial melting of Earth’s bi-polar ice sheets since the Last Glacial Maximum (LGM) has translated into a ~ 120 m amplitude stepwise sea-level rise punctuated by three major meltwater pulses that were tracked and recorded with some of the best

The neodymium (Nd) isotopic composition of seawater is a widely used ocean circulation tracer. However, uncertainty in quantifying the global ocean Nd budget, particularly constraining elusive non-conservative processes, remains a major challenge. A

International audience; During the late Miocene, global cooling occurred alongside the establishment of near-modern terrestrial and marine ecosystems. Significant (3 to 5 °C) sea surface cooling from 7.5 to 5.5 Ma is recorded by proxies at mid to hi

Optimisation of the marine Nd isotope scheme in the ocean component of the FAMOUS general circulation model
Autor: Suzanne Robinson, Ruza Ivanovic, Lauren Gregoire, Lachlan Astfalck, Tina van de Flierdt, Yves Plancherel, Frerk Pöppelmeier, Kazuyo Tachikawa
Publikováno v: eISSN
The neodymium (Nd) isotope composition (εNd) of seawater can be used to trace large-scale ocean circulation features. Yet, due to the elusive nature of marine Nd cycling, particularly in discerning non-conservative particle-seawater interactions, th

Neodymium budget in the Mediterranean Sea: Evaluating the role of atmospheric dusts using a high-resolution dynamical-biogeochemical model
Autor: Mohamed Ayache, Jean-Claude Dutay, Kazuyo Tachikawa, Thomas Arsouze, Catherine Jeandel
Publikováno v: Biogeosciences
Biogeosciences, 2023, 20 (1), pp.205-227. ⟨10.5194/bg-20-205-2023⟩
The relative importance of river solid discharge, deposited sediment remobilisation, and atmospheric dust as sources of neodymium (Nd) to the ocean is the subject of ongoing debate, the magnitudes of these fluxes being associated with a significant u

A weaker Atlantic Meridional Overturning Circulation at the Last Glacial Maximum led to a greater deep ocean carbon content
Autor: Lise Missiaen, Tobias Friedrich, Paul Spence, Jimin Yu, Kazuyo Tachikawa, Luke C Skinner, Laurie Menviel
While paleoproxy records and modelling studies consistently suggest that North Atlantic Deep Water (NADW) was shallower at the Last Glacial Maximum (LGM) than during pre-industrial times, its strength is still subject to debate partly due to differen

International audience; The early Pleistocene was driven by 41 kyr glacial cycles that have been rarely characterized in continental records, especially in South America. Most of long-term records derive from marine records (e.g. sea surface temperat
