Looking into the chemistry of why some fossil wood specimans are very well preserved over as long as tens of millions of years. Looking into the sidewall chemistry of how wood is peatified in bogs. Hoping these intersect as wood buried in the Hudon's Bay Lowlands's past tide pools would be more valuable is preserved millions of years. A Calluna heath paper mentions in one sentence that one of two cell wall layers of fossil wood may be well preserved because of a coating of phenolics from the water. Two other nearly identical layers were further away from exterior.
Also need to learn of logistics of digging into deep peat. Would probably want to wait for drier weather but the peat microsite would be more vulnerable to damage if dug into during a drought...burying the logs in too wet ground adjacent to optimal peat would be good but it may be the hardest to dig into. Drill in winter?
If you can get one tonne of carbon in each square metre as an upper limit, there are 3 million km^2 of deep wet peat (assuming that Russian bog stays wet) or so, if 2/3 of the carbon stays sequestered, that is 2000GT of carbon or 250x existing annual footprint. The wood farming and deposition process will have a footprint. Long-term rainfall models will need to be better, not flip-flopping every IPCC Issue. Below a foot or two, I'm optimistic wood will remain sequestered within deep wet peat.
