| Summary: | <!--!introduction!--> Near the front of large ice shelves, outflowing seawater containing meltwater from beneath the ice shelf can become ‘supercooled’. This supports the development of ‘sub-ice platelet layers’ (SIPLs) – accumulations of ice discs, each 2-5 mm thick, that buoyantly rise through the water column until they come to rest against the base of the sea ice. The discs coalesce to form an intricate 3-dimensional ice matrix that may extend several metres into the upper ocean. The result is a quiescent and protective marine habitat that harbours some of the highest concentrations of primary productivity on Earth, but whose viability may be threatened by subtle climate shifts. In-situ, the 3-dimensional SIPL structure can be reasonably robust. However, when samples of the SIPL are extracted the structure becomes very delicate and may disintegrate rapidly. Hence, until very recently, qualitative analysis of the integrated SIPL system – comprising the ice structure itself, the interstitial fluid, ... : The 28th IUGG General Assembly (IUGG2023) (Berlin 2023) ... |
