Few days to apply for this #PhDposition in Precambrian mudstone metal enrichment.
Are you the person to solve what happened during the Shunga event? It was a global deposition event of vast amounts of organic-rich mud in the coastal ocean that followed the Great Oxidation Event
📢PhD opportunity!
Do you want to study depositional environment and organic/hydrothermal metal enrichment in 2 Ga old sediments?
#PhDPosition is for 3 years and in the #MSCA Doctoral Network #FluxBEATS - fluxbeats.eu/

📢WE ARE HIRING!
We invite applications for a 3-year #postdoc position in multichannel seismic surveys. The research targets glacial geomorphic features in the northern Baltic Sea, aiming to reconstruct previous glacial dynamics.

The new Finnish stratigraphic classification guidelines also consider the Baltic Sea sediments.
This peer-reviewed volume is a revision of stratigraphic procedures and nomenclature in Finland. It provides practical guidance on the appropriate use of geological unit terminology in the Fennoscandian Shield area.

I am delighted to coordinate #SecuCoast, funded by @Water4AllEU.
We study groundwater-seawater interactions in coastal aquifers and the ecosystem impacts of submarine groundwater discharge in the Baltic Sea, Mediterranean Sea and Norwegian Sea.

Syvänmeren rautamangaaninodulit tuottavat happea hydrolyysillä.
Huippumielenkiintoinen ja tärkeä löytö, mutta samalla hämmentävä osoitus siitä, miten valtamerten syvyyksissä on yhä löydettävissä eliökunnan olemassaolon kannalta keskeisiä ilmiöitä.

Magnetotactic bacteria in the Baltic Sea #ferromanganese concretions produce bullet-shaped magnetosomes. The magnetosomes are spherical or cubic in the oceanic ferromanganese nodules.

📢New paper led by @JWasiljeff!
Shape of coastal sea #ferromanganese concretions is linked to biomineralization activity.
🏵️Spherical concretions are microbially more active than discoidal and crusts.
