Hello Andy: Thanks for the post! My colleague, oceanographer Jim carton and I wrote a rough draft last year on an idea of sustainably harvesting wood from the Black Sea drainage basin including the Alps, rafting down the logs and sink to the bottom of the Sea. Tom Schelling mentioned to me of this 'pickled tree' idea, but we haven't been able to track down the references and exactly what was proposed decades ago. Do you have any lead on this?
Hello Greg: On two issues you raised: 1) methane generation in anoxic environment: apparently methanogenic bacteria don't like lignin. This is evidenced by the observation that wood hardly decays in landfills while other organic matter like food decomposes quickly. While paper in landfill also decomposes (though slowly), the cellulose in wood is hardly attacked because they are incorporated together with lignin. So there is reasonable chance for long-term sequestration of woody material. 2) I was told fresh wood sinks by itself before it looses water. Or may be your are right it depends on what kind of trees? I'd love to have some references on this.
