Influence of strong iron-binding ligands on cloud water oxidant capacity

Abstract Iron (Fe) plays a dual role in atmospheric chemistry: it is involved in chemical and photochemical reactivity and serves as a micronutrient for microorganisms that have recently been shown to produce strong organic ligands. These ligands control the reactivity, mobility, solubility and speciation of Fe, which have a potential impact on Fe bioavailability and […]

Nereis Park 6: register now!

The 6th edition of the Nereis Park will take place in Logonna-Daoulas (France), from august 22 to 26 2022. The aim of this event, organised by our colleague Emma Michaud, is to bring together the international scientific community of researchers working on the mechanisms of bioturbation in marine, freshwater and terrestrial environments, at all latitudes […]

Revisiting tolerance to ocean acidification: Insights from a new framework combining physiological and molecular tipping points of Pacific oyster

Abstract Studies on the impact of ocean acidification on marine organisms involve exposing organisms to future acidification scenarios, which has limited relevance for coastal calcifiers living in a mosaic of habitats. Identification of tipping points beyond which detrimental effects are observed is a widely generalizable proxy of acidification susceptibility at the population level. This approach […]

The LEMAR at the One Ocean Summit

A maritime city “par excellence”, Brest will host the One Planet Summit for the Ocean next week, from 9 to 11 February 2022, at the Atelier des Capucins. On 9th and 10th February more than thirty events, workshops, forums, meetings and initiatives will take place to mobilise the “international maritime community” around 10 themes: OCEAN […]

Evidence that Pacific tuna mercury levels are driven by marine methylmercury production and anthropogenic inputs

Abstract Pacific Ocean tuna is among the most-consumed seafood products but contains relatively high levels of the neurotoxin methylmercury. Limited observations suggest tuna mercury levels vary in space and time, yet the drivers are not well understood. Here, we map mercury concentrations in skipjack tuna across the Pacific Ocean and build generalized additive models to […]
