TL;DR: In this article, rhodamine and sulphur hexafluoride tracers were injected into the drainage system over three melt seasons, to observe subglacial drainage properties and evolution beneath the Greenland Ice Sheet, up to 57 km from the margin.

TL;DR: In this paper, the seasonal and annual chemical evolution of solutes in cryoconite holes was studied and it was shown that dissolution of primary minerals, cyclical precipitation and dissolution of secondary carbonates, net photosynthesis over summer and net respiration during the autumnal freeze are the principal reactions which perturb the seasonal solute concentrations in the holes.

TL;DR: The contribution of ice sheets to the global biogeochemical cycle of phosphorus is largely unknown, due to the lack of field data as mentioned in this paper, but the results indicate that the ice sheet is a hot spot of phosphorus export in the Arctic.

TL;DR: In this article, hourly measurements of ice and water temperature and water electrical conductivity (EC) were recorded to broadly characterize the physical and chemical changes on daily to seasonal timescales, underscoring the importance of subsurface solar heating.

TL;DR: In this paper, a comprehensive assessment of the quality and quantity of bioavailable C, N, and P in the cryoconite holes of the McMurdo Dry Valleys is presented.
