Variety and distribution of diatom-based sea ice proxies in Antarctic marine sediments of the past 2000 years
Antarctic sea ice is an essential component of the global climate system. Reconstructions of Antarctic sea ice from marine sediment cores are a vital resource to improve the representation of Antarctic sea ice in climate models and to better understand natural variability in sea ice over centennial...
