The Antarctic Ice Core Chronology 2023 (AICC2023) and associated timescale for the European Project Ice Coring in Antarctica (EPICA) Dome C ice core
What is IACS?
The International Association of Cryospheric Sciences (IACS) is one of eight associations of the International Union of Geodesy and Geophysics (IUGG).
What is the ECS Award?
The IACS Early Career Scientist (ECS) Prize is a cash prize of €1000 awarded every two years to two early career scientists who have published the best scientific papers on a cryospheric subject as assessed by an independent evaluation committee. The objective of the prize is to recognize excellence in cryospheric science by honouring and promoting two ECS scientists, and to draw attention to the work of IACS.
The following study received the award:
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
The 2025 evaluation panel consisted of Mathieu Morlighem (Chair), Christine Hvidberg, Martin Truffer, Alex Fraser, Sophie Nowicki, Farooq Adam, Doug Brinkerhoff, and Ji-Woong Yang.
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. »
