Log jam, Mackenzie River Delta in Nunavut, Canada (IMAGE)
Caption
Scientists have mapped the world’s biggest cumulative logjam that we know of, as reported in a new study in the AGU journal Geophysical Research Letters. The woody debris stores more than 3 million tons of carbon. The study only scratches the surface of these logjams’ carbon storage—literally. Driftwood hidden by living vegetation or buried underground couldn’t be counted using their method, so the delta’s driftwood likely stores at least twice as much carbon as Sendrowski’s work found.
