Atmospheric dissolved iron deposition to the global oceans: effects of oxalate-promoted Fe dissolution, photochemical redox cycling, and dust mineralogy
global oceans oxalate-promoted Fe dissolution
2014/12/12
Mineral dust deposition is suggested to be a significant atmospheric supply pathway of bioavailable iron
(Fe) to Fe-depleted surface oceans.
Stability of Mg-sulphate minerals in the presence of smectites: Possible mineralogical controls on H2O and nutrient cycling on Mars
Stability Mg-sulphate minerals presence of smectites mineralogical controls H2O nutrient cycling Mars

Hydrated sulphate minerals, including kieserite (MgSO4·H2O), gypsum (CaSO4·2H2O), and bassanite (CaSO4·~0.5H2O), have been detected on Mars (Gendrin et al., 2005; Wray et al., 2010), and polyhydrated ...
Nitrogen cycling in a deep ocean margin sediment (Sagami Bay, Japan)
Nitrogen cycling deep ocean margin sediment Sagami Bay Japan
2014/4/18
On the basis of in situ NO3-1 microprofiles and chamber incubations complemented by laboratory-based assessments of anammox and denitrification we evaluate the nitrogen turnover of an ocean margin sed...
DOC cycling in a temperate estuary: A mass balance approach using natural 14C and 13C isotopes
DOC cycling temperate estuary A mass balance approach natural 14C 13C isotopes
2014/6/9
We measured dissolved organic carbon (DOC), dissolved inorganic carbon (DIC), and their corresponding del14C and del13C values in order to study the sources and fates of DOC in the York River Estuary ...
Formation of lithified micritic laminae in modern marine stromatolites (Bahamas): The role of sulfur cycling
Formation lithified micritic laminae modern marine stromatolites (Bahamas) sulfur cycling
2012/4/1
Microbial mats on the surfaces of modern, marine stromatolites at Highborne Cay, Ba-hamas, were investigated to assess the role of microbial processes in stromatolite forma-tion. The Highborne Cay str...
