Kart som viser hotspots og coldspots for organisk karbon i bunnsediment på norske kontinentalmarginen.

An image of the Norwegian continental margin showing hotspots and cold spots of seabed organic carbon. Hotspots are areas that are likely vulnerable to physical disturbance with respect to their climate regulating functions. They are located in the Skagerrak and central Barents Sea. Cold spots are areas that are relatively robust to physical disturbance and are found on the North Sea plateau, shelf banks in the Norwegian and southern Barents Seas and along the continental shelf break.

Mareano har kartlagt havbunnen i 20 år 🥳

Torsdag 23. oktober, presenterer Mareano både de nyeste resultatene og høydepunkt fra tidligere år på jubileumskonferansen.

Konferansen blir strømmet direkte fra kl. 9.30 og kan følges her: videoforweb.aventia.no/live/370
God på bunn! Mareano inviterer til 20-årsjubileum. I bakgrunnen vises havbunnen kartlagt med multistråleekkolodd.

We have a new estimate on how much organic carbon is buried in continental margin sediments globally.

If you are interested, come and see me on Monday, 28 Apr, 08:30–10:15 in Hall X1, Poster X1.31.

Organic carbon stocks in surface sediments (left) and accumulation rates (right) vary substantially across the Norwegian continental margin. Mapping these variations is a prerequisite for spatial management.

Organic carbon stocks in surface sediments (left) and accumulation rates (right) vary substantially across the Norwegian continental margin. Stocks are lowest on the North Sea shelf, shelf banks in the Norwegian Sea, along the shelf edge and lower slope and parts of the southern Barents Sea. Conversely, stocks are highest off the northern and western coasts of Svalbard and in a southwest-northeast oriented band from Spitsbergen Bank to Central Bank. Zero-accumulation of organic carbon is linked to the North Sea shelf, the shelf break, shelf banks in the Norwegian Sea, and Spitsbergen Bank. The main hotspot of organic carbon accumulation in terms of size and confidence is to be found in the inner part of the Norwegian Trough in the Skagerrak.

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.
