Marie Bouchet, Laboratory for Sciences of Climate and Environment, National Center for Scientific Research, France, received the award for her paper:
Bouchet, M., Landais, A., Grisart, A., Parrenin, F., Prié, F., Jacob, R., Fourré, E., Capron, E., Raynaud, D., Lipenkov, V. Y., Loutre,M.-F., Extier, T., Svensson, A., Legrain, E., Martinerie, P., Leuenberger, M., Jiang, W., Ritterbusch, F., Lu, Z.-T., and Yang, G.-M.(2023). The Antarctic Ice Core Chronology 2023 (AICC2023) chronological framework and associated timescale for the European Project for Ice Coring in Antarctica (EPICA) Dome C ice core. Climate of the Past, 19, doi:10.5194/cp-19-2257-2023
Citation by the evaluation panel:
This paper presents a new synthesis for the chronology of East Antarctic ice cores over the last 800,000 years. By integrating diverse dating tools, modeling techniques, and new ⁸¹Kr measurements, the authors reduce the dating uncertainty by a factor of 2, which is an important step forward for the paleoclimate community. Their comprehensive approach, including novel methods using oxygen isotopes in air bubbles, enhances our ability to analyze deeper ice-core layers. This work is already a reference in the field, demonstrating strong leadership in bringing together different communities and unifying multiple datasets.
Giacomo Traversa, Institute of Polar Sciences, National Research Council of Italy, Italy, received the award for his paper:
Traversa, G., and Di Mauro, B. (2024). Weathering crust formation outpaces melt melt-albedo feedback on blue ice shelves of East Antarctica. Communications Earth & Environment, 5, doi:10.1038/s43247-024-01896-52
Citation by the evaluation panel:
This innovative and elegant study investigates the effect of weathering crust formation over blue ice areas of East Antarctic ice shelves. By integrating in-situ and remote-sensing data, the authors reveal that surface weathering can increase albedo, suggesting a potential negative feedback to climate warming. Their findings challenge conventional understanding by demonstrating that weathering crust formation can outpace the melt-albedo feedback. Given the limited knowledge on this topic, this research provides new insights that will eventually inform climate models in this region.
