Seismic Anomaly

There are six sedimentary seismic sequences overlying pre-Mesozoic basement in the Mesozoic-Cenozoic sedimentary cover of the Arctic regions of West Siberia and the Kara Sea shelf. The paper describes the seismic markers characteristics and the seismic-facial features of the Paleozoic, Triassic, Jurassic, Neocomian, Apt-Cenomanian and TuronianCenozoic seismic sequences. It was concluded that the features of large Cenomanian gas pools are seismic markers associated with gas-water contacts; Apt-Albian pools are displayed on time sections by a bright spot seismic anomaly.

Intensive Growth

The objective of this study was to build a set of structural and isopach maps of seismic sequences, seismic-geological sections, paleo-sections and correlation schemes; structural-tectonic and paleotectonic analysis of Novy Port shaft; to study the influence of tectonic processes and lithological factors on the oil and gas content of Jurassic and Cretaceous sedimentary sequences. It was concluded that the formation of the structural trap of Novy Port field began in Berrias-Aptian, the most intensive growth of the structure occurs in the post-Turonian time due to the upward movement of the basement block.

In The Wild

Ranaviruses are a group of double-strand DNA viruses that infect fish, amphibians and reptiles. These viruses are responsible for mass fish and amphibian mortality events worldwide, both in the wild and at the fish and amphibian farms. The number of detected epizootics has grown significantly in recent years. In Eastern Europe and Northern Asia, including Russia, very few ranavirosis monitoring studies have been conducted, in contrast with Western Europe and America. In the present work, we used a qPCR assay to survey for the first time the amphibian populations of West Siberia (Russia) for the presence of ranaviruses. In total, we studied 252 tissue samples from six amphibian species, collected across West Siberia from the south to the Arctic regions. We report a single infected sample: a common toad (Bufo bufo) captured near Tyumen city. The phylogenetic analysis showed that the detected virus strain belongs to the CMTV lineage. This is only the second observation of Ranavirus in Russia.
