The Precambrian in the Sub-Polar Urals : the chronostratigraphic aspect.

open access: yesTransactions of the Karelian Research Centre of the Russian Academy of Sciences, 2019
New geochronological data on the Lower and Upper Proterozoic complexes of the Sub-Polar Urals are presented, where the outcropping Precambrian section in the Lyapin anticlinoriumis the stratotype for the entire Timan-Northern Urals region.

Diversity of Cyanobacteria and Algae in Biological Soil Crusts of the Northern Ural Mountain Region Assessed through Morphological and Metabarcoding Approaches

open access: yesDiversity, 2023
In mountain regions, biological soil crusts (BSCs) provide essential ecological services by being involved in primary production and nitrogen fixation. Eukaryotic algae and cyanobacteria are important photosynthetic components of these unique cryptogamic

On the role of Ural Blocking in driving the Warm Arctic–Cold Siberia pattern

open access: yesQuarterly Journal of the Royal Meteorological Society, Volume 146, Issue 730, Page 2138-2153, July 2020 Part A., 2020
Atmospheric blocking is associated with severe cold spells. Here, we investigate the role of blocking in driving the Warm Arctic–Cold Siberia pattern. We show that blocking over the Ural sector is the key dynamical process that controls the manifestation of the Warm Arctic–Cold Siberia pattern on a variety of time‐scales ranging from daily to ...

Radiospectroscopy of vein quartz of the subpolar ural deposits [PDF]

open access: yesActa Crystallographica Section A Foundations of Crystallography, 2006
Nano-crystalline calcium silicate hydrates (C-S-H gels) are formed upon hydration of Ca3SiO5 and β-Ca2SiO4, and are therefore the primary hydration products of Portland cements. Raman and IR spectra of a series of mechanochemically prepared C-S-H samples of type C-S-H(1) with Ca/Si ratios ranging from 0.4 to 1.5 reveal changes in structure dependent ...

Presentation and Evaluation of the IPSL‐CM6A‐LR Climate Model

open access: yesJournal of Advances in Modeling Earth Systems, Volume 12, Issue 7, July 2020., 2020
Abstract This study presents the global climate model IPSL‐CM6A‐LR developed at Institut Pierre‐Simon Laplace (IPSL) to study natural climate variability and climate response to natural and anthropogenic forcings as part of the sixth phase of the Coupled Model Intercomparison Project (CMIP6). This article describes the different model components, their
