That deep water is not only rich in nutrients, it also has relatively high concentrations of carbon dioxide, both because it is cold (cold water can absorb and hold more carbon dioxide than warm water) and because the decomposition of organic matter that sinks into the depths releases carbon dioxide.

Consequently, woodlands that now drain carbon will become carbon producers because plant respiration (a process in which oxygen is taken in and carbon dioxide is given out) and the decomposition of death organic matter will exceed photosynthesis processes (carbon sequestration and oxygen release).
