The role of endogenous factor in increase of ocean level for the last 140 years

Abstract

The article examines the structure and dynamics of the World Ocean level during the past 140 years. The role of endogenous factor
in constant increase of water supply and subsequent rise of the sea level is defined as dominating. Two principle cycles in the sea level fluctuations were distinguished: a high-amplitude short-term cycle (2—3 years) and a low-amplitude long-term one (40—50 years). The concurrency of two events is traced: short-term cycles and major earthquakes in oceanic regions. It was shown that it is possible to estimate the area and amplitude of the seafloor submergence in the epicenter in relation to changes in water volume. Short-term cycles of sea level fluctuations usually coincide with changes in surface layer temperatures in middle latitudes, which could be regarded as a precursor of anomalous climatic conditions in the Northern hemisphere.

Economic globalization, production internationalization, creation of international production networks

Abstract

The article is devoted to economic globalization that is considered first of all as the process of formation and development of international production networks. The article shows the differences from the previous production internalization. The specific features of commodity chains and production networks forming in the process of globalization are provided.

Long-term forecast of water surface temperature in the southeastern part of the Pacific Ocean

Abstract

The article examines the results of use of the physical-statistical method for the forecast of seasonal trend of the sea surface temperature (SST) with the lead time of 8 months and results of statistical method of SST superlong-term forecast, lead time — 1 year. In the first case mean-squared prediction error of SST according to independent data makes 0,5 оС, in the second case — 0,2 оС, that is much less than the reasonable mistake and meets practical requirements.

Structural features of upwelling in South-East Baltic

Abstract

The article examines some features of the upwelling observed in the South-East Baltic in October 2005 which were investigated by
means of comparison of the field measurement data and numerical simulated data. The article explores the upwelling which took place after calm weather when thermohaline fields had parameters close to summer ones. Upwelling was produced by North-East wind with sped of about 15 m/s and duration of about 3 days. After the gale the alongshore belt of respectively cold water of width 8 km and placed apart the shore at 8 km had been formed in an area with depth of 25 m. The temperature in the upwelling core had dropped by 4 C. Changes in thermoholine structure due to the gale were simulated by 3D numerical model, based on the Princeton Ocean Model (POM). By means of numerical simulation it was conformed that features of upwelling space structure depend upon bottom topography in an area of observation, strength of wind velocity and its duration. The dependence of the
upwelling scenario on the Froude number was obtained.

Shifts of adulterations as the result of seasonal horizontal convection under the shelf plate (numerical modeling)

Abstract

The article shows that the water dynamics induced by differential cooling in upper shelf area (down to 60 m depth) is significantly influenced by day/night variations which delays an establishing of a seasonal water-exchange in shallows. Convective exchange flows within the entire shelf region in seasonal circle requires 4—7 weeks to reach a quasisteady state. Formation of a linear portion on the horizontal temperature profile can be used as an indicator of the approaching of the flow to the steady state. Flushing time for the shelf zone under steady-state condition is 30 days and is only slightly influenced by the slope length.

The border of the open sea in accordance with hydro-chemical data in summer-autumn 2006

Abstract

As it is known [1], the variability of ocean’s natural objects is concentrated in relatively small boundary zones of transforming of
matter and energy. These active surfaces, where the leap in process’s features take place, are also known as barrier zones. These zones, which were thoroughly investigated for oceans and open seas, are not examined well enough for internal seas. More over, the very definition of the «barrier zones» which is close to the definition of «water mass» in classic hydrology doesn’t always indicate their existence at all. This paper presents an attempt of applying formal methods for zoning and of comparing the results with classic barrier zone definitions.

Distribution of heavy metals in the soils and vegetation in urban ecosystems of Kaliningrad region

Abstract

Some peculiarities of heavy metals concentrations in the accumulating layer of the urban soils and leafs of Acer platanoides and Populus alba are presented. Dependence between physical and chemical features, geochemical structure of landscapes, concentration and distribution of heavy metals is established. Correlation between similar parameters and concentration of heavy metals in leaves is not found out.
