Terrestrial inputs and in‐lake processes shape dissolved organic matter along a permafrost gradient

Limnology and Oceanography, Volume 71, Issue 11, November 2026.
Abstract Northern permafrost landscapes store large amounts of organic carbon that can enter lakes as dissolved organic matter (DOM), but links among shoreline terrestrial sources, lake‐water DOM composition, and catchment configuration remain uncertain in low‐precipitation Shield landscapes. We combined shoreline soil‐porewater and lake‐water sampling

Evaluation of deep geothermal exploration drillings in the crystalline basement of the Fennoscandian Shield Border Zone in south Sweden

Geothermal Energy, 2021
The 3.1- and 3.7-km-deep FFC-1 and DGE-1 geothermal explorations wells drilled into the Precambrian crystalline basement on the southern margin of the Fennoscandian Shield are evaluated regarding experiences from drilling, geological conditions, and ...

Simulator‐Based Bayesian Inference of Enhanced Geothermal Reservoir Properties

Journal of Geophysical Research: Machine Learning and Computation, Volume 3, Issue 5, October 2026.
Abstract Inversions of dynamic multi‐scale multi‐physics subsurface system properties rely on the effective sampling of high‐dimensional parameter spaces and are thus notoriously difficult to perform. The associated models are defined by complex nonlinear relationships with potentially stochastic components, which lead to analytically intractable ...

NEW DATA ON POSTGLACIAL SEISMIC DISLOCATIONS IN THE FENNOSCANDIAN SHIELD-RUSIAN PLATE CONTACT ZONE, PUDOZH DISTRICT, KARELIA, RUSSIA

Геодинамика и тектонофизика
Like the entire Fennoscandian Shield, Karelia is a low-seismicity region. Fenoscandia displays numerous geological evidence of the Holocene natural disasters, which followed the last ice sheet degradation.

Quantifying Natural Hydrogen‐Helium Sources and Dynamic Accumulation in Global Sedimentary Basins

Earth's Future, Volume 14, Issue 10, October 2026.
Abstract Despite the scientific and economic importance of hydrogen and helium, their crustal budgets remain poorly quantified. This study systematically assesses the accumulation of natural hydrogen and helium in global sedimentary basins by integrating predictive models for both gases with H2/He ratios.

Dissolved organic matter composition in the Fennoscandian Shield deep terrestrial biosphere (FT-ICR-MS), 2018 and 2019

, 2021
Copious amounts of organic carbon are stored for long periods of time in deep continental groundwaters. Little is known about its composition and cycling, mainly due to the difficulties in obtaining sample material.

Komatiitic explosive volcanism and its tectonic setting in Finland, the Fennoscandian (Baltic) Shield [PDF]

Bulletin of the Geological Society of Finland, 1990
The variously explosive komatiitic volcanism in Finland was virtually confined to the Archaean continental segment, where it occurred in the Lapland and Kuhmo‒ Suomussalmi greenstone belts between 3.0 Ga and 2.5 Ga, in the continental borderland at 1.97 ...

Palaeoenvironmental and climatic changes from the lateglacial of the Saalian to the Late Weichselian in central Poland: a multiproxy study from Józefów

Boreas, Volume 55, Issue 4, Page 1073-1101, October 2026.
Józefów site is a case study which provides a detailed record of environmental and climate changes and confirms the main traces of the landscape morphogenesis of the Late Pleistocene established in central‐eastern Europe. This study presents a multiproxy reconstruction of palaeoenvironment under variable climatic conditions from the retreat of the ...

The Fennoscandian Shield deep terrestrial virosphere suggests slow motion ‘boom and burst’ cycles

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 ...
