Tiivistelmä
Biogeochemical processes (e.g., physical control by minerals) exert a predominant role in organic carbon (OC) cycle – regardless of molecular structure. The preservation of OC by iron (Fe) has been emphasized in soil studies but only to a small extent been explored in aquatic and sediment environments. Recently the concentration of Fe is significantly increasing in many freshwaters, causing brownish color, its consequences and effects on C cycling remain largely unknown.
This project studies the effects of Fe in the cycling of OC in both aquatic and sediment environments. The aim is to reveal the role and its mechanisms of Fe in the mineralization and preservation of OC. The results are applicable to the OC cycle estimation in natural and also disturbed (e.g., ore-mining) catchments.
