Results and Impact The aim of this workshop is to bring together interdisciplinary Antarctic research expertise to discuss the fate of nutrients that have accumulated in Antarctic snow and glacier ice. We also wish to discuss the in-situ and "downstream" processes that govern the export and potential impact of nutrients to ice marginal ecosystems such as the oceans. Emphasis will be given to the relevant processes during the first day of the workshop, leading to a presentation of the key tools for quantifying cryospheric change, biogeochemical fluxes and Antarctic ecosystem response in the second. Thereafter, we will identify crucial research needs and strategies for the next ten years.
