Ecosystem modeling: challenges in simulating the dissolved organic carbon

Dissolved Organic Carbon (DOC) is an important carbon budget within ecosystem, especially for aquatic ecosystem including oceanic ecosystem.

Conventional DOC investigations mainly focus on DOC measurements in either soil profile or stream discharge. These measurements generally cannot explain where does DOC come from and how much DOC will be exported into the ocean. However, these studies have provided much insights of what biogeochemical processes are responsible for DOC dynamics.

So the question is can we quantitatively estimate DOC in terrestrial ecosystem based on existing knowledge.

I will provide more information on this topic in the coming months.

There are a few processes need to be simulated following the path of DOC.

DOC production, consumption, and transportation on surface (mainly in litter);DOC production, consumption and transportation in subsurface (mainly in soil);DOC consumption and transportation in hydrological network;In some scenarios, DOC transportation in groundw…
