The Fennoscandian Shield deep terrestrial virosphere suggests slow motion ‘boom and burst’ cycles [PDF]
Communications Biology, 2021 Karin Holmfeldt et al. sequence metagenomes and metatranscriptomes of viruses in deep groundwaters down to 448 m below the surface. The results reveal ecological dynamics of viruses including slow motion ‘boom and burst’ cycles and a ‘kill the winner ...

HETEROGENEOUS LITHOSPHERIC STRUCTURE OF THE FENNOSCANDIAN SHIELD: SEISMIC DATA
Геодинамика и тектонофизика, 2022 A generalization has been obtained based on the data for deep seismic studies on longitudinal DSS profiles (explosion seismology) and seismological evidence found for local and distant earthquakes (earthquake seismology) in the Fennoscandian Shield over ...

Terrigenous dissolved organic matter persists in the energy-limited deep groundwaters of the Fennoscandian Shield [PDF]
Nature Communications, 2022 Dissolved organic matter in the Fennoscandian Shield deep continental bedrock fracture waters of varying characteristics and ages carries a strong terrigenous signature, and only a small proportion of this potential energy source links to the deep ...

Energy efficiency and biological interactions define the core microbiome of deep oligotrophic groundwater [PDF]
Nature Communications, 2021 Ecological constraints on microbial niches in oligotrophic deep groundwaters remain elusive. This study provides support for the existence of a common core microbiome in two deep groundwater biomes of the Fennoscandian Shield using a genome-resolved ...

Seismic situation in the northern parts of the Karelian craton (Fennoscandian Shield)
Transactions of the Karelian Research Centre of the Russian Academy of Sciences, 2018 The seismic situation in the northern parts of the Karelian craton (Fennoscandian Shield) was studied. The geological structure of the territory is briefly described. The events of natural and man-made genesis recorded by seismic stations of the Karelian

Some features of deformation structures in an esker on the southern margin of the Fennoscandian shield [PDF]
Bulletin of the Geological Society of Finland, 2018 As a result of melting of the last ice sheet in the southeastern edge of the Fennoscandian shield, ridge structures called eskers were formed. One of these eskers is the subject of our study.
