Experimental investigation of the direct shear strength parameters of compacted snow

Abstract. Compacted snow is utilized as a building material in various construction and engineering applications across global high-latitude regions. For the safety assessment of snow and ice structures in cold regions, cohesion and internal friction angle are key shear strength...

Antarctic Circumpolar Current creates a boundary limiting the meridional dispersal of bacteria in the Southern Ocean

Impact statement As the world's largest ocean current in terms of volume transport, the Antarctic Circumpolar Current (ACC) significantly affects the movement of heat and water in the Southern Ocean. However, the impact of the ACC on the biogeographic distribution of marine bacte...

Early-mid Holocene Ross Sea extreme wave heights reflect sea ice retreat and ocean-atmosphere interactions

Abstract Antarctic coastal systems preserve valuable records of postglacial environmental change and extreme storm events. On Inexpressible Island, Ross Sea, we integrated geomorphic mapping, boulder measurements, exposure dating, radiocarbon constraints, and hydrodynamic analysi...
