CE20009 Constraining the Impact of Arctic Amplification in the Nordic Sea: A biogeochemical approach (CIAAN) Celtic Explorer 2020

During the survey 13 CTD , 11 Multinet Vertical and 7 Multinet Oblique casts were successfully carried out. 5 Multicores, 2 Box Corer and 12 gravity core casts were also conducted. 3 Argo floats were also deployed. The research linked to the project 'Constraining the Impact of Arctic Amplification in the Nordic Sea (CIAAN)' will support global efforts to improve our understanding of Essential Climate Variables (ECVs) in the Nordic Seas, which is a key region for the formation of North Atlantic Deepwater and the uptake of atmospheric carbon dioxide (pCO2).

Specifically, CIAAN aims to define a more comprehensive description of biogeochemical processes in the Nordic Seas and will provide transformative insights into how ECVs are recorded in geologic archives to improve the “long-term monitoring, surveying and modelling to understand the processes and feedback mechanisms between the ocean and atmospheric systems” (Joint Programming Initiative Healthy and Productive Seas and Oceans).
