RAPID: US-Korean collaboration to build a Ross-Amundsen Ice Core Array (RAICA) along the West Antarctic coastline

RAICA

Description/Abstract
The West Antarctic coastline is changing rapidly: it is thinning, losing mass, and buttressing ice shelves that are critical for future stability of the ice sheet are retreating. Despite observed change caused by ice-ocean-atmosphere interactions perturbed by both internal and forced climate processes (e.g., tropical Pacific Ocean variability, ozone depletion, greenhouse gas warming), there are few direct measurements along this coastline. Ice rises, which are regions of grounded ice within ice shelves, are ideal ice-core sites. Ice rises line this region, allowing for reconstruction of coastal climate and environmental parameters dating back decades to millennia at annual resolution. A 150-m-long ice core from Canisteo Peninsula, an ice rise in this region, will expand our understanding of critical processes relevant to observed coastal change over a timespan a century. The project forms a new collaboration between a U.S. researcher and the South Korean Polar Research Institute (KOPRI), who will provide the bulk of the logistics, including the use of their research vessel, RV ARAON. This project relied on KOPRI logistics to accomplish the field aspects of this project. The participants deployed on the RV ARAON from December 2023 – February 2024. The U.S.-South Korean team drilled two 150-m ice cores along the local ice divide. The specific site was chosen based on both scientific value and logistical constraints associated with the RV ARAON cruise and sea ice conditions. The ice-core data will be used to characterize climate variability, extremes, and trends along the coastal West Antarctic Ice Sheet — over recent decades and centuries. This award reflects NSF's statutory mission and has been deemed worthy of support through evaluation using the Foundation's intellectual merit and broader impacts review criteria.
