TL;DR: This work uses a global inverse model to quantify the mean ocean circulation during the 1980s, 1990s and 2000s, and estimates the impact of decadal circulation changes on the oceanic CO2 sink using a carbon cycling model, and finds that during the 1990s an enhanced upper-ocean overturning circulation drove increased outgassing of natural CO2, thus weakening the globalCO2 sink.

TL;DR: Using an inverse model combined with a global compilation of 228Ra observations, this article showed that SGD is the dominant pathway for dissolved terrestrial materials to the global ocean, and this necessitates revisions for the budgets of chemical elements including carbon.

TL;DR: In this article, a new estimate of the oceanic anthropogenic CO2 (Cant) sink over the industrial era (1780 to present), from assimilation of potential temperature, salinity, radiocarbon, and CFC-11 observations in a global steady state ocean circulation inverse model (OCIM), is presented.

TL;DR: In this article, a data-constrained ocean circulation model is used to characterize the distribution of water masses and their ages in the global ocean, which is constrained by the time-averaged temperature, salinity, and radiocarbon distributions in the ocean, as well as independent estimates of the mean sea surface height and sea surface heat.

TL;DR: In this article, the authors present a new model of the biological pump that assimilates satellite and oceanographic tracer observations to constrain rates and patterns of organic matter production, export, and remineralization in the ocean.
