‘Phenomenal’ logjam in the Canadian Arctic stores millions of tonnes of carbon: study
1 May 2023
Researchers say they have mapped the world’s largest known cumulative logjam in the Canadian Arctic and it holds millions of tonnes of carbon, representing an important but understudied part of the carbon cycle.
A study published in Geophysical Research Letters earlier this month describes how the scientists mapped almost 415,000 individual deposits of wood in the Mackenzie River Delta in the Northwest Territories, with the pileup stretching nearly 52 square kilometres.
