Antarctica has the potential to contribute more than a meter of sea-level rise by 2100 in response to the occurring global climate warming. At the same time intense precipitation events over specific regions of Antarctica can determine the sign of the total mass balance change of the entire ice sheet. Previous work by the current project PI (Gorodetskaya et al., 2014, "The role of atmospheric rivers in anomalous snow accumulation in East Antarctica", GRL) demonstrated that extreme precipitation events that recently occurred over East Antarctica were associated with atmospheric rivers - narrow and long-band features of intense moisture transport from lower latitudes. This project extended the analysis to the entire ice sheet, and used unique measurements gathered during the Antarctic Circumnavigation Expedition (December 2016-March 2017), in order to explore the role of atmospheric rivers in precipitation over the Antarctic ice sheet and the Southern Ocean.
