Dissolved Mn(III) is a key redox intermediate in sediments of a seasonally euxinic coastal basin Abstract. Manganese (Mn) is an essential micronutrient and key redox intermediate in marine systems. The role of organically complexed dissolved Mn(III) (dMn(III)-L) as an electron acceptor and donor ...

Happy to share our new publication where we show the importance of dissolved Mn(III) in a seasonally euxinic marine system. We applied a reactive transport model to our field data to discern different processes that are impacted by Mn(III).

Last week we investigated metal and greenhouse gas dynamics around Svalbard as part of my Veni project. Very proud to have led the hard working and enthusiastic team on board the Norwegian G.O. Sars.

Middernachtzon op Spitsbergen: op expeditie naar fytoplankton | Radboud Universiteit Op 5 juli vertrekken zullen vijf wetenschappers van de Radboud Universiteit onder leiding van Wytze Lenstra monsters nemen van de zeebodem en de waterkolom in één van de fjorden van Spitsbergen.

Tomorrow we leave with a group of scientist from the @ribesresearch.bsky.social and NIOZ to Svalbard. There we will investigate Fe and Mn dynamics in the seafloor and water column as part of my Veni project. See a post about the work we will do (in Dutch):

Sulfide Toxicity as Key Control on Anaerobic Oxidation of Methane in Eutrophic Coastal Sediments Coastal zones account for 75% of marine methane emissions, despite covering only 15% of the ocean surface area. In these ecosystems, the tight balance between methane production and oxidation in sedim...

Check our new study where we investigated the impact of sulfide on the efficiency of methane oxidation in the eutrophic Stockholm Archipelago.

Today our fieldwork equipment will be brought to University of Bergen where it will be loaded onto the Norwegian G.O. Sars. We will see our stuff back in Svalbard where we will board the ship to investigate trace nutrient cycling as part of my NWO Veni project @ribesresearch.bsky.social
