Project Description:
The overall aim of this research project is to determine how climate-induced changes in permafrost thaw will influence organic carbon (OC) stream biogeochemical processing among Arctic ecosystems regions. We will address the effects of thermokarst activity in microbial organic matter utilization among freshwaters in Arctic regions by measuring in-stream OC and extracellular enzymatic activity of aquatic microorganisms. We will provide paramount information on how transported OC is processed in-stream, identify the key drivers of biological OC degradation, and thus contributing on our understanding on the OC-permafrost fate either being mineralized in-stream, contributing to C-climate feedback, or exported downstream to the sea. The project will requiere to obtain small samples of water (<5L) and moss, microalgae and sediments (<5Kg in total).
