'Cryosphere meltdown' will impact Arctic marine carbon cycles and ecosystems, new study warns

A new study led by Jochen Knies from the iC3 Polar Research Hub has found worrying signs that climate change may be undermining the capacity of #Arctic #fjords to serve as effective #carbon sinks. The findings suggest that the capacity of polar #oceans to remove carbon from the #atmosphere may be reduced as the world continues to heat up.

Knies and his collaborators discovered that rapid changes in the Arctic are transforming vibrant fjord ecosystems like Kongsfjorden in #Svalbard. Published in Communications Earth & Environment, their findings document not only a shift in phytoplankton communities due to melting ice but also a worrying decline in the capacity of these fjords to sequester carbon.

Warmer waters can enhance #phytoplankton growth during sunlit summers, presenting an initial opportunity for increased productivity. However, as the waters become stratified, essential nutrients become harder to access, leading to a double-edged sword: while we may see a rise in phytoplankton #biomass, the efficiency of CarbonCapture could decline.
