Fjords are estimated to bury 18 millions tonnes of organic carbon each year globally. But how reliable are these large-scale estimates? A new study takes a closer look at the seabed of fjords around Stavanger, Norway, and finds that the answer depends on where you look. ic3.uit.no/news/global-...

Not as glamorous as #BlueCarbon ecosystems, the humble #sediments on the #seafloor off Norway accumulate and store a lot of organic #carbon. Link to the paper: t.co/ZFXkokTmR5 We are now assessing the potential impacts of mobile bottom fishing on vulnerable organic carbon stocks.
Organic carbon accumulation rates of the geomorphological units shallow shelf, deep shelf, glacial trough, slope and abyss. The left figure shows mean organic carbon accumulation rates averaged over the five morphological units. Vertical lines indicate one standard deviation. The rates are highest in glacial troughs. The right figure shows the organic carbon sink sizes. About half the accumulation of organic carbon is occuring in glacial troughs. The total accumulation of organic carbon is 6 teragram per year.Organic carbon stocks in surface sediments of the geomorphological units shallow shelf, deep shelf, glacial trough, slope and abyss. The left figure shows mean organic carbon stocks averaged over the five morphological units. Vertical lines indicate one standard deviation. The right figure shows organic carbon reservoir sizes of the five geomorphological units. Reservoir sizes are highest in glacial troughs. In total, the surface sediments of the Norwegian continental margin store 814 teragram of organic carbon.

Interesting news story on @mongabay.bsky.social. I could add that we have also quantified the amount of organic carbon that accumulates and is stored in Norwegian seabed sediments. We found that glacial troughs ('superfjords') are centres of organic carbon accumulation. doi.org/10.1038/s432...
