The Arctic Ocean is changing faster than any other ocean region in the world. Uptake of anthropogenic carbon, amplified warming, sea ice reduction, coastal erosion, and enhanced riverine runoff are driving important changes in the Arctic Ocean ecosystems through changes in primary production and ocean acidification. However, the current understanding of primary production and ocean acidification in the Arctic remains highly uncertain. Furthermore, projections of both processes by Earth-System Models diverge strongly in this region.
During this webinar, Dr. Terhaar presented:
(1) a modelling study that quantifies the impact of terrigenous nutrients from rivers and coastal erosions on Arctic Ocean primary production, a process that was (wrongly?) neglected so far, and
(2) results from two studies on emergent constraint on ocean acidification in the Arctic Ocean that suggests that projections of Earth-System Models collectively underestimated the extent of future ocean acidification in the Arctic Ocean.
