The element silicon (Si) is required for the growth of silicified organisms in marine
environments, such as diatoms. These organisms consume vast amounts of Si together with …

Over the past few decades, we have realized that the silica cycle is strongly intertwined with
other major biogeochemical cycles, like those of carbon and nitrogen, and as such is …

The Southern Ocean plays a critical role in regulating global climate as a major sink for
atmospheric carbon dioxide (CO2), and in global ocean biogeochemistry by supplying …

PISCES-v2 is a biogeochemical model which simulates the lower trophic levels of marine
ecosystem (phytoplankton, microzooplankton and mesozooplankton) and the …

Ocean Biogeochemical Dynamics provides a broad theoretical framework upon which
graduate students and upper-level undergraduates can formulate an understanding of the …

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 …

Diatoms are a major component of phytoplankton community. They tend to dominate under
natural high-nutrient concentrations, as well as during artificial Fe fertilisation experiments …

Despite the growing number of in situ iron fertilization experiments, the efficiency of such
fertilization to sequester atmospheric CO2 remains largely unknown. For the first time, a …

The availability of iron is known to exert a controlling influence on biological productivity in
surface waters over large areas of the ocean and may have been an important factor in the …

Observations have shown that large areas of the world ocean are characterized by lower
than expected chlorophyll concentrations given the ambient phosphate and nitrate levels. In …
