Mechanism of solar-terrestrial relations and changes of atmospheric circulation     

Václav Bucha  Reviewer F. Rein  Reviewer J. Bochníček 《Studia Geophysica et Geodaetica》1977,21(3-4):350-360

Summary As a result of investigating the relations between the variations of geomagnetic activity and meteorological factors [1, 2] a mechanism of solar-terrestrial relationships and a model of the changes of atmospheric circulation in the Northern Hemisphere are proposed; this provides an explanation of the causes of the fluctuation of the climate, of dry and cold periods and differing vegetation conditions in various years in dependence on the intensity of geomagnetic activity.  相似文献

Water flooding of the Oseberg Øst oil field,Norwegian North Sea: Application of formation water chemistry and isotopic composition for production monitoring     

I.A. Munz  H. Johansen  O. Huseby  E. Rein  O. Scheire 《Marine and Petroleum Geology》2010,27(4):838-852

This case study demonstrates how natural heterogeneities of formation and injection waters can be applied to a number of production related applications, extending into the mature life of a reservoir. Break-through of injection water, identification and characterisation of production intervals and evaluation of responses to operational events are some of the possible applications during production.The Oseberg Øst oil field in the North Sea represents a complex situation with commingled production from all Brent Group formations. The Sr isotope composition is an excellent parameter for defining the natural baseline of formation water, with a good spatial resolution and vertical stratification. Aquifer water from the Utsira Formation is injected for pressure support, and reinjection of produced water has also been applied since the onset of water production. Utsira Formation water has high Mg, low Ba and low Sr content compared to the reservoir formation waters. Isotopic compositions (δD and ⁸⁷Sr/⁸⁶Sr) are also distinct. A non-reactive behaviour of Ba and Sr is verified from binary cross-plots and geochemical modelling. Break-through of injection water could be identified in five production wells based on Ba/Mg ratios. In one of the reservoir compartments (Beta Saddle), water injection points were changed after approximately three years. The Ba/Mg ratio could also identify the second injection water break-through in one of the wells due to an intermediate period of higher formation water content. Since the Sr content in the Utsira water is low, the ⁸⁷Sr/⁸⁶Sr ratio is a good natural tracer for formation water movements even at high ratios of injected water. In particular, the vertical stratification of ⁸⁷Sr/⁸⁶Sr is useful for quantifying production from different intervals in commingled wells. A methodology for using operational events, such as production allocations or shut-ins, for characterisation of production zones is discussed.  相似文献

Carbon isotope systematics of the Cambrian–Vendian aquifer system in the northern Baltic Basin: Implications to the age and evolution of groundwater     

Valle Raidla  Kalle Kirsimäe  Rein Vaikmäe  Enn Kaup  Tõnu Martma 《Applied Geochemistry》2012

Groundwater in the Cambrian–Vendian aquifer system has a strongly depleted stable isotope composition (δ¹⁸O values of about −22‰) and a low radiocarbon concentration, which suggests that the water is of glacial origin from the last Ice Age. The aim of this paper was to elucidate the timing of infiltration of glacial waters and to understand the geochemical evolution of this groundwater. The composition of the dissolved inorganic C (DIC) in Cambrian–Vendian groundwater is influenced by complex reactions and isotope exchange processes between water, organic materials and rock matrix. The δ¹³C composition of dissolved inorganic C in Cambrian–Vendian water also indicates a bacterial modification of the isotope system. The corrected radiocarbon ages of groundwater are between 14,000 and 27,000 radiocarbon years, which is coeval with the advance of the Weichselian Glacier in the area.  相似文献   

An overview approach to seismic awareness for a “quiescent” region     

Alena Rein  Ross B. Corotis 《Natural Hazards》2013,67(2):335-363

The Denver Region in Colorado, USA, is used as an example of the seismic vulnerability of a region that is not generally considered seismically active. The HAZUS (Hazards United States) natural hazard vulnerability program of United States and an integral geographical information system are used to create the regional distribution of Denver’s potential consequences of an earthquake. Two realistic scenario earthquakes are employed based on a detailed study of seismic activity in the region. Outcomes include casualties, displaced households, building damage by construction material type, hospital functionality, highway bridge functionality, and infrastructure recovery rates. Demographic information includes the use of public transportation, elderly population, and vulnerability based on education, income, and race. Additionally, the type and frequency of communication among key planning agencies and other organizations in the region are investigated through the use of personal interviews as well as a survey to determine the degree to which these agencies consider seismic risk in their communication and coordination planning.  相似文献   

Accumulation in Svalbard glaciers deduced from ice cores with nuclear tests and Chernobyl reference layers   总被引：1，自引：0，他引：1

Mean net annual balance and the related spatio-temporal variations have been determined on the basis of well-dated artificial layers in shallow ice cores (Chernobyl, 1986, and atmospheric thermonuclear tests, mainly in 1961-62 in Novaya Zemlya). Seventy ice cores from 13 Svalbard glaciers have been analysed. On each glacier, in its accumulation area and at the highest elevation, one ice core was recovered down to about 40 m and sampled for radioactivity measurements to determine the 1986 and 1962-63 layer (1954 was the initial date of the nuclear tests). For each glacier, at least five complementary ice cores from the accumulation area were analysed to determine the Chernobyl reference layer. Six ice cores exhibit both the Chernobyl and nuclear tests layers and are of special interest in this study.
This work provides new data on the deposition rates of natural and artificial radioisotopes. Using ice cores samples from the Arctic glaciers, even with superimposed ice accumulation, it is possible to distinguish between the Chernobyl and the nuclear tests fallouts. This work also shows that the mean annual net balance did not significantly change for at least five ice core locations in the Svalbard glaciers for the two periods extending from 1963 to 1986 to the recent date of drilling.  相似文献   

Electron capture decay of cosmic rays     

John R. Letaw  J. H. Adams Jr.  Rein Silberberg  C. H. Tsao 《Astrophysics and Space Science》1985,114(2):365-379

Cosmic-ray nuclei are close to fully ionized during their passage through the Galaxy. Electron capture decay is rare among these nuclides because most do not have bound electrons. Under certain conditions, specifically low energies and/or high charges, electron capture becomes an essential factor in determining cosmic-ray composition. In this paper we discuss the general nature of electron capture decay in cosmic rays and describe specific measurements which can reveal the existence of electron capture decay, and energy and density-dependent processes in the interstellar medium.  相似文献
