Early Holocene Antarctic climate variability - Drivers and consequences as captured by major ions in the Roosevelt Island Climate Evolution (RICE) ice core

Abstract: <p>In a warming world, rapid disintegration of the West Antarctic Ice Sheet (WAIS) remains a primary uncertainty in the Intergovernmental Panel on Climate Change (IPCC) sea level rise projections. A deep ice core was drilled at the northeastern edge of the Ross Ice Shelf as part of the Roosevelt Island Climate Evolution (RICE) project. The site is located in a major drainage pathway of the marine based WAIS and the primary focus of the RICE project is to provide new insights into our understanding of the… Show more

“…These sources are increasingly thought to be important drivers of sea-salt variability, as coastal locations around Antarctica show peaking sea-salt contributions during the winter (Wagenbach et al, 1998;Abram et al, 2013). Seasonal Na + records at RICE also showed this pattern, with values peaking during winter (Eling, 2019).…”

“…Deposition at RICE is characterised by frequent, large austral winter precipitation events (Emanuelsson et al, 2015) when antarc-tic sea ice extent is at its maximum. While this suggests that Na + and ssCa 2+ signal could be more sensitive to sea ice extent and winter precipitation, it may also reflect open ocean conditions (Eling, 2019). Regardless, Na + and ssCa 2+ reflect transport over the marine sector.…”
