Carbon balance in subglacial hydrochemical systems
Editors’ Highlight—This paper addresses a hotly-debated topic as to whether rock weathering below glaciers is a critical and long-term source of atmospheric CO2 consumption or whether some of the CO2 consumed may be from decomposing organic material. The authors compared a model of subglacial pH and alkalinity with actual measurements from 20 glaciers and ice sheets. The findings support the currently less-accepted notion that organic decomposition is small and open systems dynamics are more likely.
