Biological production of ligands influences iron chemistry in hydrothermal systems
For the first time, siderophores and siderophore-producing microbes were determined in 11 distinct hydrothermal plume environments.
Microbial
Nutrient-OMICS coupling approach reveals unexpected actors for atmospheric carbon sequestration
Sharma and colleagues investigated the role of clay minerals in strengthening the marine biological pump.
When covariance of trace metals and prokaryotic taxa are tagging water masses (Southern Indian Ocean)
Zhang and colleagues investigated the potential reciprocal links between diverse prokaryotic taxa and concentrations of trace elements.
Iron limitation also affects the twilight zone
Li and co-workers established the distribution and uptake of siderophores along the Pacific meridional section (GP15 GEOTRACES cruise)…
Breaking down disciplinary silos in marine sciences, a key to climate forecasting
Alessandro Tagliabue exposes how ocean modelling must evolve to take the biological complexity of the surface ocean into account.
Microbial trace metal trafficking on marine particles
This study provides evidence for the processing of nine particulate trace metals in multiple manners by diverse microbial communities.
New BioGEOTRACES data sets: Connecting pieces of the microbial biogeochemical puzzle
Microorganisms play a central role in the transfer of matter and energy in the marine food web. Microbes depend on micronutrients (e.g. iron, cobalt, zinc, and a host of other […]
Siderophores facilitate microbial adaptation to iron limitation in the eastern tropical Pacific Ocean
Siderophores are organic compounds secreted by microbes to facilitate iron uptake. Using new methods to characterize trace metal organic ligands in seawater, Boiteau and colleagues (2016, see reference below) measured […]
Prokaryotic communities display elevated trace metal concentrations in Pacific oxygen deficient zone
Local particulate maxima in many bioactive trace metals (cadmium, Cd; cobalt, Co; nickel, Ni; vanadium, V; and zinc, Zn) are found in the upper Oxygen Deficient Zone (ODZ), coincident with […]
