«These long
turnover times suggest that root production and
turnover in forests have been overestimated,» the authors write, «and that sequestration of anthropogenic atmospheric
carbon in forest soils may be lower than currently estimated.»
1998: ``... the average
turnover time of phytoplankton
carbon in the ocean is on the order of a week or less, total and export production are extremely sensitive to external forcing and consequently are seldom in steady state.
The difference between residence (
turnover)
time and adjustment
time is a bit counterintuitive (and IMHO made more difficult to understand in the terminology used in AR5), but if you are going to write a paper suggesting that the
carbon cycle scientists are wrong, then the onus is on you to make sure you really understand it first.
The metabolic processes that are responsible for plant growth and maintenance and the microbial
turnover, which is associated with dead organic matter decomposition, control the cycle of
carbon, nutrients, and water through plants and soil on both rapid and intermediate
time - scales.
Reservoir
turnover times (a measure of how long the
carbon stays in the reservoir) range from a few years for the atmosphere to decades to millennia for the major
carbon reservoirs of the land vegetation and soil and the various domains in the ocean.
The calculation also requires specification of the
turnover times of
carbon in the ocean and on land, because fossil fuel burning implies a continuous release of isotopically light
carbon to the atmosphere.
