Open-water estimates of aquatic ecosystem metabolism: potential, limitations and current challenges

Brückstraße 3a, 39114 Magdeburg, Seminar Room

The study of carbon fluxes in inland waters is a major topic in current aquatic biogeochemistry. Final aim is to understand the role of rivers, lakes and reservoirs in the global carbon cycle. While aquatic metabolism has been a hot topic in aquatic ecology since the early 20. century, technological developments in the last two decades have prompted a widespread application of the so-called open-water method in both lotic and lentic ecosystems. This method relies on the diel variability of dissolved oxygen and aims to estimate rates of primary production and respiration directly at the ecosystem scale. While the limitations of the open-water approach to ecosystem metabolism remain the same as initially described decades ago, recent conceptual and methodological developments allow more precise estimates of metabolic rates in both lotic and lentic ecosystems.
