@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 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.

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.

📢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.

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

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

Joyful ensemble of core slicers. Day 1 of our cruise week of sampling for organic geochemistry and Fe and Mn cycling in the Bothnian Sea
