CANAIMOC WORKSHOP

The accumulation of anthropogenic carbon (Cant) in the North Atlantic is strongly linked to the Meridional Overturning Circulation (MOC) (ref. 1), which is highly variable and predicted to decline during the 21st century as the Earth warms (ref. 2). At 26°N, the upstream extension of the Gulf Stream, namely the Florida Current (FC), is confined to a very narrow passage of about 90 km and 800 m depth off the east coast of Florida (Florida Straits). This very intense current (~32 Sv, ref. 3) comprises the bulk of the Cant-loaded upper northward limb of MOC (refs. 1, 4). Hence, gaining a better understanding of the magnitude, variability, and likely future trends in North Atlantic carbon accumulation in response to changing upper MOC, that is, changes in volume, heat, carbon and nutrient transports as observed across the Florida Straits, is crucial for determining the fate of global carbon stocks and the impacts on North Atlantic ecosystems.

Within this context, the CANAIMOC Workshop* aimed to favour discussion and exchange of ideas on the study of the role of the Gulf Stream on the carbon cycle in the North Atlantic.

The CANAIMOC Workshop (February 2021) consisted of three separate events:

# 1-day Educational Seminar Session (with students), 17 Feb
         

# 2-day Science Seminar Session (open to scientific community), 23-24 Feb


# 1-day Project Discussion Session (with collaborators): 25 Feb

(*) This workshop was supported by LOPS (Laboratory for Ocean Physics and Satellite remote sensing) and ISblue project, Interdisciplinary graduate school for the blue planet (ANR-17-EURE-0015) and co-funded by a grant from the French government under the program "Investissements d'Avenir".
