Changes in the C, N, and P cycles by the predicted salps-krill shift in the southern ocean

*Correspondence: Miquel Alcaraz, Institut de Ciènces del Mar, CSIC, P. Marítim de la Barceloneta 37-49, 08003 Barcelona, Catalonia, Spain e-mail: miquel@icm.csic.es The metabolic carbon requirements and excretion rates of three major zooplankton groups in the Southern Ocean were studied in February 2009. The research was conducted in the framework of the ATOS research project as part of the Spa...

Dissolved organic sulfur in the ocean: Biogeochemistry of a petagram inventory.

Although sulfur is an essential element for marine primary production and critical for climate processes, little is known about the oceanic pool of nonvolatile dissolved organic sulfur (DOS). We present a basin-scale distribution of solid-phase extractable DOS in the East Atlantic Ocean and the Atlantic sector of the Southern Ocean. Although molar DOS versus dissolved organic nitrogen (DON) rat...

HORIZONS Biological or microbial carbon pump? The role of phytoplankton stoichiometry in ocean carbon sequestration

Once fixed by photosynthesis carbon becomes part of the marine food web. The fate of this carbon has two possible outcomes, it may be respired and released back to the ocean and potentially to the atmosphere as CO2 or retained in the ocean interior and/or marine sediments for extended time scales. The most important biologically mediated processes responsible for long-term carbon storage in the...

New nutrients exert fundamental control on dissolved organic carbon accumulation in the surface Atlantic Ocean.

The inventories of carbon residing in organic matter dissolved in the ocean [dissolved organic carbon (DOC)] and in the atmosphere as CO2 are of the same order of magnitude, such that small changes in the DOC pool could have important consequences in atmospheric carbon and thus climate. DOC in the global ocean is largely formed in the sunlit euphotic zone, but identifying predictable controls o...

Effects of eustatic sea - level change , ocean dynamics , and nutrient utilization on atmospheric p CO 2 and seawater composition over the last 130 000 years : a model study

We have developed and employed an Earth system model to explore the forcings of atmospheric pCO2 change and the chemical and isotopic evolution of seawater over the last glacial cycle. Concentrations of dissolved phosphorus (DP), reactive nitrogen, molecular oxygen, dissolved inorganic carbon (DIC), total alkalinity (TA), C-DIC, and CDIC were calculated for 24 ocean boxes. The bi-directional wa...
