| Summary: | <!--!introduction!--> The Circumpolar Deep Water (CDW) is the main heat source for the Antarctic margins. Its onshore transport influences key processes that have a global impact, such as the melting of Antarctic ice shelves and the process of Antarctic Bottom Water (AABW) formation. The warming observed in some regions of the Antarctic margins has been directly linked to the inflow of the CDW onto the continental shelf, which has also shown a shoaling and warming trend. As a result, these regions are also those that experienced greatest ice-shelf volume loss. Ice shelf collapse threatens to reduce buttressing and accelerates glacial flow seaward. In addition to its contribution to sea level rise, the ice loss also increases the freshwater flux into the Antarctic coastal seas, modifying the properties of the Antarctic Shelf Bottom Water (ASBW) and, consequently, AABW formation. Despite its importance, the study of processes connected to Antarctic coastal dynamics has been challenging due to both coarse ... : The 28th IUGG General Assembly (IUGG2023) (Berlin 2023) ... |
