Characteristics of the deforming bed: till properties on the deglaciated Antarctic continental shelf

Journal of Glaciology, 2018
Contemporary ice stream flow is directly linked to conditions at the ice/bed interface, yet this environment is logistically difficult to access.

Anisotropy and cyclic loading characteristics of a stiff Bolders Bank glacial till at Cowden [PDF]

E3S Web of Conferences
Glacial tills are widespread across the world, common in northern Europe and found under the North and Baltic Seas. Their geological and geotechnical characterisation is important to the geotechnical design of a wide range of onshore and offshore ...

The engineering properties of glacial tills [PDF]

Geotechnical Research, 2018
Glacial tills are a product of the glacial processes of erosion, transportation and deposition and could have been subjected to several glacial cycles and periglacial processes to the extent that they are complex, hazardous soils that are spatially variable in composition, structure, fabric and properties, making them very difficult to sample, test and

Sediment behavior controls equilibrium width of subglacial channels

Journal of Glaciology, 2017
Flow-frictional resistance at the base of glaciers and ice sheets is strongly linked to subglacial water pressure. Understanding the physical mechanisms that govern meltwater fluxes in subglacial channels is hence critical for constraining variations in ...

Climate Change Threatens Micronutrient Density of European Winter Wheat

Advanced Science, EarlyView.
Micronutrients are vital for human health. Wheat is a major staple crop and a significant source of minerals and B‐vitamins. The impact of climate change on their content remains largely unknown. We evaluated micronutrient levels in European winter wheat grown under historical and projected climate conditions. Our findings indicate that future climates

Millennial-scale fluctuations of palaeo-ice margin at the southern fringe of the last Fennoscandian Ice Sheet [PDF]

The Cryosphere
The paper presents the first terrestrial record of millennial-scale palaeo-ice margin oscillations at the southern fringe of the last Fennoscandian Ice Sheet (FIS) during the last glacial cycle.

Lithostratotypes for Weichselian and pre-Weichselian sediments in southern and western Finland [PDF]

Bulletin of the Geological Society of Finland, 1990
In this paper we define stratotypes for glacial and associated sediments in southern and western Finland. The Kauhajoki Formation in southern Ostrobothnia (Pohjanmaa) and the Kela Formation in western Uusimaa, comprise a complex sequence of sediments ...

Zinc Exposure Causes Disulfidptosis to Induce Miscarriage by Up‐Regulating GATA1/METTL1/SLC7A11 Axis

Advanced Science, EarlyView.
Zn exposure up‐regulates GATA1, promoting GATA1‐mediated METTL1 and SLC7A11 transcription. It also enhances METTL1‐mediated m7G modification on SLC7A11 mRNA, increasing SLC7A11 mRNA stability. Ultimately, Zn exposure up‐regulates SLC7A11 at both transcriptional and post‐transcriptional levels, causing disulfidptosis. Knockdown of murine Slc7a11, Gata1,
