This paper reviews carbon sequestration mechanisms in coastal upwelling ecosystems and suggests a model to predict climate change impacts on carbon dioxide uptake.

The paper compares food-web structures in tuna spawning habitats of the Gulf of Mexico and Argo Basin, finding higher ecosystem efficiency in the Argo Basin due to differences in zooplankton herbivory and nutrient cycling.

The paper analyzes environmental data from Lagrangian ocean experiments, showing that density surfaces better capture variability than depth, confirming the Lagrangian nature of the experiments.

The paper quantifies carbon export and sinking particle characteristics in the eastern Indian Ocean, finding net remineralization in the deep euphotic zone and similar patterns to the Gulf of Mexico.

The paper quantifies primary productivity and nitrogen fixation in the eastern Indian Ocean, showing nitrogen recycling and N2 fixation support ecosystem productivity.

The paper quantifies microbial carbon flows in the spawning region of Southern Bluefin Tuna off NW Australia, showing Prochlorococcus dominates production and grazing in the upper euphotic zone.

The paper examines protist export dynamics in subtropical and subantarctic waters, finding taxon-specific patterns in their loss during particle sinking and remineralisation.

The paper measures carbon fixation rates and taxonomic composition of small phytoplankton in different oceanic regions, suggesting phago-mixotrophy may help alleviate iron limitation in certain populations.

The paper develops an algorithm to predict primary productivity in the southern California Current Ecosystem using irradiance, nutrient, and chlorophyll data, achieving good agreement with independent measurements.
