Anthropogenic ocean acidification over the twenty-first century and its impact on calcifying organisms
TLDR
13 models of the ocean–carbon cycle are used to assess calcium carbonate saturation under the IS92a ‘business-as-usual’ scenario for future emissions of anthropogenic carbon dioxide and indicate that conditions detrimental to high-latitude ecosystems could develop within decades, not centuries as suggested previously. Expand
Global patterns of marine nitrogen fixation and denitrification
A new quasi-conservative tracer N*, defined as a linear combination of nitrate and phosphate, is proposed to investigate the distribution of nitrogen fixation and denitrification in the world oceans.… Expand
Redfield ratios of remineralization determined by nutrient data analysis
A nonlinear inverse method is applied to nutrient data upon approximately 20 neutral surfaces in each of the South Atlantic, Indian, and Pacific basins, between 400 and 4000 m depth. By accounting… Expand
Ocean Biogeochemical Dynamics
Trends in the sources and sinks of carbon dioxide
Efforts to control climate change require the stabilization of atmospheric CO2 concentrations. This can only be achieved through a drastic reduction of global CO2 emissions. Yet fossil fuel emissions… Expand
High-latitude controls of thermocline nutrients and low latitude biological productivity
The ocean's biological pump strips nutrients out of the surface waters and exports them into the thermocline and deep waters. If there were no return path of nutrients from deep waters, the… Expand
Climate-driven trends in contemporary ocean productivity
TLDR
Global ocean NPP changes detected from space over the past decade are described, dominated by an initial increase in NPP of 1,930 teragrams of carbon a year, followed by a prolonged decrease averaging 190 Tg C yr-1. Expand
Spatial coupling of nitrogen inputs and losses in the ocean
TLDR
It is concluded that oceanic nitrogen fixation is closely tied to the generation of nitrogen-deficient waters in denitrification zones, supporting the view that nitrogen fixation stabilizes the oceanic inventory of fixed nitrogen over time. Expand
Atmospheric carbon dioxide and the ocean
The ocean is a significant sink for anthropogenic carbon dioxide, taking up about a third of the emissions arising from fossil-fuel use and tropical deforestation. Increases in the atmospheric carbon… Expand
An improved method for detecting anthropogenic CO2 in the oceans
An improved method has been developed for the separation of the anthropogenic CO 2 from the large natural background variability of dissolved inorganic carbon (C) in the ocean. This technique employs… Expand
