Object of study. The article was devoted to investigation of the depth structure of the Earth’s crust and upper mantle along the Mezen–Timan–Pechora seismic profile (MEZTIMPECH), crossing the southern parts of the Mezen syneclise, the Timan ridge and the Pechora syneclise. Total profile length was 525 km. Materials and methods. In the course of writing the article, the data obtained by performing seismic surveys using the earthquake exchange wave method were used. The processing involved seismic data using the methods of deep seismic sounding, reflected waves, a common depth point, a correlated method of refracted waves, and materials from well geophysical surveys. In interpreting the research results, generalizing models of the deep structure of the territory were employed. Research results. As a result of the interpretation of the records of the method of exchange waves of earthquakes and the subsequent mathematical modeling, a geological and geophysical section was constructed to a depth of about 100 km and a number of seismic boundaries were identified. The pivotal boundaries of the exchange were: Ф0 – the surface of the Riphean folded basement, Ф – the surface of the pre-Riphean crystalline basement, M – the surface of Mohorovich, identified with the roof of the upper mantle. Additionally, horizons K1–K4 – in the crust of the Earth, M1, M2 – in the upper mantle were traced. Four regional geoblocks were distinguished in the seismic section, differing in depth of the basement surface, the Moho sectionand the underlying structural features of the consolidated crust: the Kirov-Kazhim aulacogen, the Vychegda depression, the Timan ridge and the Pre-Ural downfold. Conclusions. The results of deep seismic studies reflected regional features of the structure of the Earth’s crust and were the basis for the construction of tectonic models of large geological objects.

Несколькими организациями в последние десятилетия были выполнены региональные геофизические исследования различными методами в пределах Северного Кавказа. Вдоль Чегемского профиля (перевал Китлод – г. Буденновск) впервые к северу от зоны сочленения структур Большого Кавказа со Скифской плитой получены две чёткие субгоризонтальные сейсмические границы, разделяющие, вероятно, платформенный чехол, переходный комплекс и консолидированный фундамент. Платформенный чехол, представленный палеозойскими отложениями большой мощности, по аналогии со многими территориями мира, где уже обнаружены и разведаны уникальные месторождения нефти, включая шесть залежей углеводородов, в числе которых и газоконденсатное Кармалиновское месторождение в зоне Передового хребта, может оказаться перспективным на нефтегазовые структуры. Результаты глубинных геофизических работ последних лет могут скорректировать направление поисков углеводородов в регионе. Известные в этом районе Предкавказья восточнее Чегемского профиля нефтегазоносные структуры осадочного чехла приурочены к выделяемым по геофизике поднятиям в консолидированной коре или к их краевым частям. Это даёт основание ожидать наличие углеводородов, вероятно, в материнских палеозойских образованиях Чернолесской впадины, а также соответственно новые перспективные участки и в осадочном чехле по её обрамлению. Several organizations in recent decades have carried out regional geophysical studies by various methods within the North Caucasus. Along the Chegem profile (the Kitlod Pass – town of Budennovsk), for the first time to the north of the junction zone of the Greater Caucasus structures with the Scythian plate, two distinct subhorizontal seismic boundaries, probably sharing a platform cover, a transitional complex and a consolidated foundation have been obtained. The platform cover, represented by large Paleozoic deposits, by analogy with many areas of the world where unique oil deposits, including six hydrocarbon deposits, and the gas condensate Karmalinovskoye deposit in the zone of the Forward Ridge, have already been discovered and explored, may prove promising for oil and gas structures. The results of deep geophysical studies of recent years can correct the direction of hydrocarbon exploration in the region. The oil-and-gas-bearing structures of the sedimentary cover, known in this region of the Ciscaucasia to the east of the Chegem profile, are confined to uplifts in geophysics in the consolidated crust or to their marginal parts. This gives grounds to expect the presence of hydrocarbons, probably in the parent Paleozoic formations of the Chernoslavskaya depression, and also, respectively, new promising sites in the sedimentary cover along its framing.

The Hill

Wishing to measure Skiddaw geometrically, the author employed a staff about 28 feet long. Its graduation commenced at 0°, placed about 3 feet above its lower end, from which to the top was ex­actly 25 feet. A stationary barometer was next placed 10 yards above the lake, and its variation and that of a thermometer were noted every half hour. Another barometer and thermometer were then set upon the summit of the mountain, and their respective heights accurately observed. A telescope, with cross wires, was then care­ fully levelled, and the wires made to intersect the highest point of the mountain. It was then pointed in the direction of the most con­venient descent, and the staff carried down the hill till its top exactly coincided with the cross wires, the level of the telescope being care­ fully preserved. The perpendicularity of the staff was ascertained by plumb lines; and as it was seldom more than 40 feet from the telescope, no allowance was necessary for the earth’s curvature. The most exact mode of managing the pole, says the author, was to stop my assistant when I observed its top to be about an inch above the cross wires, and then it was pressed gradually into the earth till an exact coincidence was obtained. The telescope was then carried down to the pole, levelled and placed in exact correspondence with zero. The pole was again carried to a new station, and this mode continued for fifty yards of descent. The barometer was then again set up and examined, and the process continued to the foot of the mountain . The height of Skiddaw, by levelling, was 1012 yards 3½ inches. Annexed to this paper are the results of several barometrical observations made on the summit of Skiddaw, and continued at different distances of fifty yards each down to the foot of the mountain.

Public Criticism

This essay explores the reception of ‘nuclear winter’ at the North Atlantic Treaty Organization (NATO). This response is paradigmatic of how scientific predictions can work as stimuli for science diplomacy activities, and either inflate or deflate these forecasts’ public resonance. Those who elaborated the theory in the early 1980s predicted that the environmental consequences of a future nuclear conflict would have been catastrophic; possibly rendering the earth uninhabitable and leading to the extinction of humankind. This prospect was particularly problematic for the Western defence alliance, since it was difficult to reconcile with the tenets of its nuclear posture, especially after the 1979 Dual Track decision, engendering concerns about the environmental catastrophe that the scientists predicted. Thus, NATO officials refrained from commenting on nuclear winter and its implications for the alliance’s deterrence doctrine for some time in an effort to minimize public criticism. Meanwhile, they progressively removed research on nuclear winter from the set of studies and scientific debates sponsored by NATO in the context of its science initiatives. In essence, NATO officials ‘traded’ the promotion of these problematic studies with that of others more amenable to the alliance’s diplomacy ambitions.

In the research of vertical movements of the earth’s crust, examination of statistical correlations between the measured vertical movements of the earth’s crust and territorial geo-indexes is accomplished with the help of mathematical statistical analysis. Availability of the precise repeated levelling measuring data coupled with the preferred research methodology offer a chance to determine and predict recent vertical movements of the earth’s crust. For the inquiry into recent vertical movements of the earth’s crust, a Lithuanian class I vertical network levelling polygon was used. Drawing on measurements made in the polygon, vertical velocities of earth’s crust movements were calculated along the following levelling lines. For determining the relations shared by vertical movements of the earth’s crust and territorial geo-parameters, the following territory-defining parameters are accepted. Examination of the special qualities of relations shared by vertical movements of the earth’s crust and geo-parameters in the territory under research contributed to the computation of correlation matrices. Regression models are worked out taking into consideration only particular territory-defining geo-parameters, i.e. only those parameters which exhibit the following correlation coefficient value of the vertical earth’s crust movement velocity: r ≥ 0.50. A forecast of the velocities pertaining to vertical movements of the earth’s crust in the territory under examination was made with the application of regression models. Further in the process of this research, a map was compiled specifying the velocities of vertical movements of the earth’s crust in the territory. In the eastern part of this territory, the earth’s crust rises at a rate of up to 3 mm/year; while in the western part of it, the earth crust lowers at a rate of up to –1.5 mm/year. In order to pinpoint territories characterised by temperate and regular rising/lowering or intensive rising/lowering, a map of horizontal gradients of recent vertical earth crust movements in the territory enclosed by levelling polygon was compiled.
