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.
BioGEOSCAPES
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.
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.
Trace metal quotas in small flagellates: diatoms are challenged!
Sofen and colleagues found that in natural plankton assemblages and in culture, small flagellates operated at the lower range of iron quotas.
A vivid picture of particle distribution and sources in the Arctic Ocean
Extensive description of particle concentrations and chlorophyll-a fluorescence distribution along Arctic GEOTRACES sections.
First direct measurements of luxury iron uptake in natural phytoplankton communities: surprising results!
This study demonstrates the importance of biology and ecology to understanding iron biogeochemistry.
Who produces methylmercury in the global ocean?
The UNEP Minamata Convention was ratified in August 2017 and aims to protect human health from mercury exposure by reducing anthropogenic, inorganic, mercury emissions. The most toxic and biomagnifying mercury […]
Diatoms use a stolen bacterial gene to commit iron piracy
Joint Science Highlight with US-Ocean Carbon & Biogeochemistry (US-OCB). Much of the primary production in low-iron marine environments is carried out by diatoms, and therefore the details of how these […]
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 […]
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 […]
