The increased use of hydropower is currently driving the greatest surge in global dam
construction since the mid-20th century, meaning that most major rivers on Earth are now …

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 …

Increased loadings of nitrogen (N) from fertilizers, top soil, sewage, and atmospheric
deposition are important drivers of eutrophication in coastal waters globally. Monitoring …

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

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 …

Global increases in atmospheric CO2 and temperature are associated with changes in
ocean chemistry and circulation, altering light and nutrient regimes. Resulting changes in …

We estimate the global rate of biogenic silica production in the ocean to be between 200
and 280× 1012 mol Si yr− 1. The upper limit is derived from information on the primary …

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

The net inputs of silicic acid (dissolved silica) to the world ocean have been revised to
6.1±2.0 teramoles of silicon per year (1 teramole= 1012 moles). The major contribution …

Diatoms are the world's largest contributors to biosilicification and are one of the
predominant contributors to global carbon fixation. Silicon is a major limiting nutrient for …
