Journal ArticleDOI
The silica balance in the world ocean: a reestimate.
Paul Tréguer,David M. Nelson,Aleido J. van Bennekom,David J. DeMaster,Aude Leynaert,Bernard Quéguiner +5 more
TL;DR: 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).
Journal ArticleDOI
Production and dissolution of biogenic silica in the ocean: Revised global estimates, comparison with regional data and relationship to biogenic sedimentation
TL;DR: In this article, the global rate of biogenic silica production in the ocean was estimated to be between 200 and 280 × 1012 mol Si yr−1, which is 30-50% lower than several previous estimates, due to new data indicating lower values for both the relative contribution of diatoms to primary productivity and their Si/C ratios.

A review of the Si cycle in the modern ocean: recent progress and missing gaps in the application of biogenic opal as a paleoproductivity proxy
Olivier Ragueneau,Paul Tréguer,Aude Leynaert,Robert F. Anderson,Mark A. Brzezinski,David J. DeMaster,Richard C. Dugdale,Jack Dymond,Gerhard Fischer,Roger Francois,Christoph Heinze,Ernst Maier-Reimer,Véronique Martin-Jézéquel,David M. Nelson,Bernard Quéguiner +14 more
TL;DR: In this article, a review of the Si cycle in the modern ocean starts with the mechanisms that control the uptake of silicic acid (Si(OH)4) by diatoms and the subsequent silicification processes, the regulatory mechanisms of which are uncoupled.
Journal ArticleDOI
Mercury methylation, demethylation and reduction rates in coastal and marine surface waters of the Mediterranean Sea
Mathilde Monperrus,Emmanuel Tessier,David Amouroux,Aude Leynaert,Pierre Huonnic,Olivier F. X. Donard +5 more
TL;DR: In this paper, the relative contribution of photochemical versus biological processes to Hg transformation mechanisms is compared with major biogeochemical parameters (i.e., hydrological and biological data).
