Abstract

©2019. The Authors. Groundwater dependent ecosystems (GDEs) are defined by their reliance on subterranean water resources, but GDE food webs may also depend on it as an energy source. Mazumder et al. (, https://doi.org/10.1029/2018JG004925), show a clear dependency of a local GDE food web on very old, potentially geological, carbon sourced from palaeo-groundwater discharge in the arid Great Artesian Basin in Australia. These findings support the emerging paradigm that ancient groundwater carbon is an important component of inland water carbon cycling and contemporary ecosystem functioning. Future work is needed to determine what proportion of total GDE energy needs are derived from groundwater carbon across a range of geological and hydroclimatic settings.
