Markus Diesing @mdiesing.bsky.social · 30/09/2026Fjords 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-...ic3.uit.noGlobal assessments may overestimate carbon accumulation in fjords: new studyiC3 produces ground-breaking new insights into how the links between ice sheets, carbon cycles and ocean ecosystems are impacting life on earth 110

Markus Diesing @mdiesing.bsky.social · 29/06/2026"These findings add to growing evidence that intensive bottom trawling can reduce the capacity of muddy shelf sediments to function as long-term carbon sinks and climate regulators." 001
Markus Diesing @mdiesing.bsky.social · 29/06/2026New important study showing that chronic mobile bottom fishing is decreasing organic carbon content and organic carbon density in the western Irish Sea mud belt. 3431
Markus Diesing @mdiesing.bsky.social · 06/05/2026There is a growing body of evidence showing that fjords are heterogeneous in terms of seabed sediments and the properties of organic carbon they store. This has implications for upscaling from local studies to regional, national or global levels. We make suggestions how upscaling could be improved. 010

Markus Diesing @mdiesing.bsky.social · 04/12/2025In addition, spatial protection of impacted stocks might lead to the displacement of fishing fleets. Protection of vulnerable organic carbon in currently unfished areas ensures that fishing displacement will not impact vulnerable stocks. 000
