Journal ArticleDOI
Reconstruction of the history of anthropogenic CO(2) concentrations in the ocean.
TL;DR: The results indicate that ocean uptake of anthropogenic CO2 has increased sharply since the 1950s, with a small decline in the rate of increase in the last few decades, and suggest that the terrestrial biosphere was a source of CO2 until the 1940s, subsequently turning into a sink.
Journal ArticleDOI
Global ocean storage of anthropogenic carbon

TL;DR: In this article, the authors present a review of the progress made in the application of inverse and data assimilation techniques which combine ocean interior estimates of C-ant with numerical ocean circulation models.
Journal ArticleDOI

TL;DR: The global integrated sea-air anthropogenic carbon dioxide (CO 2 ) flux from 1990 to 2009 is determined from models and data-based approaches as part of the Regional Carbon Cycle Assessment and Processes (RECCAP) project.
Journal ArticleDOI
Dissolved organic carbon export and subsequent remineralization in the mesopelagic and bathypelagic realms of the North Atlantic basin
Craig A. Carlson,Dennis A. Hansell,Norman B. Nelson,David A. Siegel,William M. Smethie,Samar Khatiwala,Meredith M. Meyers,Elisa R. Halewood +7 more
TL;DR: In this article, the authors presented three meridional transects conducted in the North Atlantic as part of the US Climate Variability (CLIVAR) Repeat Hydrography program in 2003.
Journal ArticleDOI

TL;DR: In this paper, a reversible scavenging model of rare earth element neodymium removal from the ocean on the ocean circulation fields from the MIT general circulation model using the transport matrix method is proposed.
