Isotopic variations of meltwater from ice by isotopic exchange between liquid water and ice

Journal of Glaciology, 2019
Predicting the isotopic modification of ice by melting processes is important for improving the accuracy in paleoclimate reconstruction. To this end, we present results from cold room laboratory observations of changes in the isotopic ratio (D/H and 18O ...

An ice-sheet scale comparison of eskers with modelled subglacial drainage routes [PDF]

, 2015
Eskers record the signature of channelised meltwater drainage during deglaciation providing vital information on the nature and evolution of subglacial drainage.

Chemical characteristics of hydrologically distinct cryoconite holes in coastal Antarctica

Annals of Glaciology, 2018
Cryoconite holes play a significant role in the nutrient cycling on glaciers and can be regarded as a storehouse of nutrients that are generated through microbial and photochemical activities.

Variability in Timing and Transport of Pleistocene Meltwater Recharge to Regional Aquifers

Geophysical Research Letters, 2021
The impacts of Pleistocene glaciation on groundwater flow systems in sedimentary basins are widely recognized, but the timing and distribution of subglacial recharge events remain poorly constrained. We investigate the spatial and temporal variability of

Impacts of glacial and sea-ice meltwater, primary production, and ocean CO2 uptake on ocean acidification state of waters by the 79 North Glacier and northeast Greenland shelf

Frontiers in Marine Science, 2023
The waters adjacent to the Nioghalvfjerdsbræ (79 North Glacier, 79NG) are influenced by Greenland Ice Sheet (GrIS) melt, sea-ice meltwater, and waters on the adjacent northeast Greenland shelf (NEGS).

The influence of tides on the marine carbonate chemistry of a coastal polynya in the south-eastern Weddell Sea [PDF]

Ocean Science, 2022
Tides significantly affect polar coastlines by modulating ice shelf melt and modifying shelf water properties through transport and mixing. However, the effect of tides on the marine carbonate chemistry in such regions, especially around Antarctica ...
