Research team from GTK has revealed that iron-manganese concretions from the Gulf of Finland serve as detailed archives of environmental change.

Seven thousand years of environmental variability are recorded by a coastal iron-manganese concretion, according to microstructure, magnetic, geochemical, and isotopic geochemical analyses of a concretion from the Baltic Sea.

Itämerelle omistettu teemapäivä tarjoaa hetken pysähtyä pohtimaan, mitä voimme tehdä meren puolesta nyt ja tulevaisuudessa.

Estuaries play a vital role in the coastal environment by filtering pollutants and nutrients from catchment runoff. In areas where acid sulfate (AS) soils are abundant, the importance of the estuary ...

Deep beneath the surface of the Japan Trench, one of Earth's most extreme environments, scientists have uncovered a surprising secret. Using advanced X-ray imaging, they discovered a thriving deep-sea...

The contents have changed our understanding of life under the ocean. Find out more.

New scans of the bottom of the Japan Trench reveal extensive burrow structures and evidence of regular "reset" events that help sea creatures survive in the ocean's deepest reaches.

To better understand bioturbation in the hadal zone, the authors here examine sediment cores collected from depths of more than 7.5 km. They characterise biogenic sedimentary structures, colonization ...
