A French study published in Biogeosciences finds anthropogenic carbon stored in the subpolar North Atlantic (A25-OVIDE hydrographic section) rose by more than one-third over the past 30 years. Researchers used ship observations, ocean reanalysis and neural-network reconstructions to produce monthly concentration and transport time series for natural and anthropogenic carbon; natural carbon showed no significant trend while anthropogenic carbon increased ~33%, attributed mainly to higher atmosphe

A French study published in Biogeosciences finds anthropogenic carbon stored in the subpolar North Atlantic (A25-OVIDE hydrographic section) rose by more than one-third over the past 30 years. Researchers used ship observations, ocean reanalysis and neural-network reconstructions to produce monthly concentration and transport time series for natural and anthropogenic carbon; natural carbon showed no significant trend while anthropogenic carbon increased ~33%, attributed mainly to higher atmospheric anthropogenic carbon. Authors say observed changes are primarily linked to human emissions and that tracking ocean uptake and redistribution is essential for climate projections.
