| Summary: | The West Antarctic Ice Sheet (WAIS) is vulnerable to warming as a result of anthropogenic climate change, with the potential to contribute several metres to global sea level rise over the coming centuries. The Thwaites and Pine Island glaciers are already undergoing acceleration due to climate change, threatening the stability of the WAIS. There is a need to understand the stability of the WAIS during warm periods, such as the Last Interglacial (LIG) when the WAIS is proposed to have retreated, and the Holocene prior to anthropogenic warming. Ice core records can be used to reconstruct climatic changes and infer past ice sheet configurations. However, existing long-term ice records are sparse. Two drilling campaigns were carried out under the WACSWAIN project, aiming to contribute two new ice records to refine the uncertainties of WAIS stability in warm periods. One drilled an ice core to bedrock (651m) on Skytrain Ice Rise, adjacent to the Ronne Ice Shelf; a second used a novel drilling technology (Rapid ... |
