@JWasiljeff presented results on mineral magnetic properties of Baltic Sea #ferromanganese concretions at #IGC2024 Busan. Crust, discoidal and spherical concretions differ from each other due to the formation environment and #microbial communities. @GTK_FI #marinegeology

@GTK_FI ferromanganese group at #IGC2024. We will present mineral magnetic, geochemical, mineralogical and microbiological results of the Baltic Sea #ferromanganese concretions in the T12-S11 Marine Minerals session. @JWasiljeff @geomikrobiologi #marinegeology

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. yle.fi/a/74-20100994

📢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. @SuomenAkatemia #Fermaid project @GTK_FI #marinegeology agupubs.onlinelibrary.wiley.com/doi/10.1029/20…

Hyper-bb submersible hyperspectral backscatter instrument by @sequoiasci arrived at @GTK_FI The instrument enables characterizing suspended particles by measuring backscatter over wavelengths 430-700 nm Another piece of @FINMARI1 research infrastructure #marinegeology @aka_firi

It is a windier day today, but here is a nice photo from Day 2. @JWasiljeff is filling jars for sediment gas analyses.
