The coupled zinc-silicon cycle paradox illuminated

The strong similarities between zinc (Zn) and silicon (Si) vertical profiles have led many studies to suggest the uptake of Zn in diatom frustules, followed by simultaneous remineralisation at depth. […]

First major ocean sections of silicon isotopes

The GEOTRACES programme is providing the first major ocean sections of silicon isotopes, δ30Si, aiding efforts to use this proxy to reconstruct diatom silica production in both the modern and […]
