Transfer and transformations of oxygen in rivers: A review from AquaKlif
2021-07-01
In an article in the high-ranking journal Earth-Science Reviews, David Piatka and his co-authors representing five subprojects in AquaKlif take a close look at the role of dissoved oxygen in rivers. Its continous recharge is vital for aquatic organisms, and endangered by many factors. As rivers integrate biogeochemical information of catchments, their oxygen dynamics may reflect ecosystem and landscape health.
The authors summarize the most important sources and sinks of dissolved oxygen in river systems and extend considerations to associated water compartments and fluxes including lakes, reservoirs, soils, groundwater and the hyporheic zone. Analysis of over 170000 measurements of dissolved oxygen in the GLObal RIver CHemistry database reveals different influencing factors on a continental scale. The review article concludes how monitoring can be improved for a better understanding of transfer and transformations of oxygen in rivers as essential integrators of landscapes. This publication is a prime example for joint and interdisciplinary approaches in a team effort in AquaKlif. Publication under:
