Groundwater and Glaciers


Subglacial lakes in Antarctica might have nutrient-rich groundwater flowing into them, say scientists investigating the origin of the water in ice streams.

Ice streams are huge, fast-flowing glaciers that meander across Antarctica. They are responsible for nearly all of the Antarctic’s contribution to sea-level rise, yet scientists have little understanding of where the water flowing through them comes from. This means that the contents of the subglacial lakes which lie underneath these streams is also a mystery.
