Aim. This article discusses the possibility of reducing ecological costs and risks during exploration of oil and gas fields. To this end, we propose to reduce the number of exploratory drilling works performed using unjustified non‐productive wells. Such a problem can be solved with the help of innovative seismic‐acoustic methods of direct deposit exploration.Methods. The method of microseismic noise estimation (MNE) in application to hidden hydrocarbon de‐ posits is proposed. When implementing the MNE algorithms, Chebyshev spectroscopy and analysis of the noise in terms of Gaussian distribution were used.Results. The hardware im‐ plementation of the MNE method is presented. The key component of the hardware complex is presented by an autonomous microprocessor 3D seismic module. The seismic module registers signals across the frequency range of 0.5‐40 Hz with a level of spectral density of self‐noise not higher than 0.5 nm×Hz‐1/2. Presented both in land and sea design, the module is compact and mobile.Conclusion. The application of the MNE method in prospecting and exploration allows identification and exclusion of obviously non‐productive wells from drilling, as well as reduc‐ tion of the total number of wells more than by twofold. For the Caspian region, this indicator is expected to be higher. As a result, the method will provide a significant reduction in the envi‐ ronmental consequences of the oil and gas industry as a whole.

“…The timeline of extinction roughly coincides with the period of increasing industrialization and chemical pollution in the Caspian Sea region (Lattuada et al, 2019). For example, the first onshore oil well was drilled near Baku (Azerbaijan) in 1848 and the development of offshore oil fields began in 1949 (Zhiltsov et al, 2016). Moreover, the invasion of nonnative species into the Caspian Sea has peaked in parallel, with a variety of negative effects on the native fauna (Shiganova et al, 2023).…”

To be alive or not to be alive: Radiocarbon data provide new perspective on species diversity in the Caspian Sea

The Caspian Sea is undergoing a severe biodiversity crisis. However, estimates of current extinction rates are difficult to obtain due to the lack of reliable pre‐Anthropocene baseline data. For example, because the majority of endemic gastropod species was described from “fresh looking” shells, it remains unclear which species still existed prior to the Anthropocene. This study therefore used the species‐rich microgastropod family Hydrobiidae to assess the extent to which endemic species were collected alive during the Anthropocene. Literature and database searches were performed. In addition, 14C dating was conducted on “fresh looking” shells collected in the Caspian Sea during the last 150 years. The literature review revealed that 75% of the “recent” species are only known from empty shells and 25% were recorded with a soft body. The 14C data showed that all “recent” specimens examined had an age between 1624 cal BC and 1888 cal AD. Two species studied predate the beginning of the Anthropocene. Two other species potentially or likely existed during the Anthropocene. This suggests that the number of endemic species still present at the beginning of the Anthropocene is lower than previously thought. The data also suggest that there was a substantial loss of species between the late 18th century and the 1950s and that only two endemic hydrobiid species have recently been found alive. These findings further contribute to the notion of a severe biodiversity crisis in the Caspian Sea. For accurate estimates of current extinction rates of Caspian Sea gastropods, pre‐Anthropocene biodiversity data need to be further corroborated. Particularly, studies are required to clarify the taxonomic status of the dubious taxa and a possible “collection crisis” in the Caspian Sea due to decreasing sampling efforts in recent decades. In addition, comprehensive IUCN assessments are urgently required.

“…Следует отметить, что США накопили значительный опыт в разработке подобных документов, посвященных отдельным странам и регионам. Так документы, определяющие долгосрочную стратегию США, были разработаны в отношении Центральной Азии и Каспийского региона [3], которые находились в фокусе американской политики после распада СССР.…”

The article examines the recently published documents on the priorities of the U.S. in the Arctic region. At the end of 2022, the U.S. Department of Energy published the document titled “Arctic Strategy”, and the White House released “The New National Strategy for the Arctic Region”. The latter strategic document presents the U.S. policy for the development of the Arctic over the next ten years. It addresses a number of issues, in particular rising geopolitical tension and the climate crisis, which significant effect the stable development of the Arctic re-gion. In the time of global rivalry between Russia and the West, the United States has stepped up its policy in the Arctic. The creation of these documents confirms the willingness of the United States to strengthen own presence in the region. The key directions of the U.S. policy in the Arctic, as well as areas of greatest interest to the USA are clearly defined in the strategic documents. The development of naval forces, construction of new ships, and further study of the climatic features of the Arctic region are addressed. Moreover, the documents express the U.S. firm intention to continue development of energy projects in the Arctic, and deepen cooperation with allies and partners by using multilateral mechanisms.
