Sochi, the largest health resort in the country, is taken as an example to analyze a negative anthropogenic impact on the Black Sea coast environment, in particular on surface and sea waters. The paper gives the results of an integrated pollution
of the North Sea. This morphology seems to be slightly controlled by the lithology and structure of the Tertiary substratum. Some remarkable planation surfaces, paleovalleys and other morphological features have been identified.
The detailed analysis of more than 12,000 km of high resolution reflection seismic profiles has shed some new light on the morphology of the erosion surface at the top of the Tertiary substratum in the Belgian and northern French sectors
The A. reviews various prescriptions and parameterizations for snow and ice albedo which have been employed in sea-ice model simulations. Sea-ice albedo is also briefly discussed in terms of its interactions with ice thickness and atmospheric
conditions (radiation balance, clouds) in modelled atmospheres. Some recommendations for improving sea-ice albedo representation in numerical models are proposed.

. The methodology is demonstrated for the Kara/Barents Sea in spring 1984 using data from the Nimbus-7 Scanning Multichannel Microwave Radiometer. The analysis shows conditions in the Barents Sea to be largely controlled by ice advection, while the variance

the sea level dropped: surface (river and irrigation) drainage; underground discharge of dissolved salts to the Aral Sea; salts income with liquid and solid precipitation; deflation of salts to the atmosphere, from the seasurface; accumulation in the bays
The estimate of the salt balance of the Aral Sea is of general importance when considering the problem of the necessity and possibility to keep the Aral Sea in definite borders. The A. considers in detail every point of the salt balance before

Eustasy can no longer be defined as world wide simultaneous changes in sea level, but must be redefined as ocean level changes or any absolute sea level changes regardless of causation and including both the vertical and horizontal changes

Causes of interannual variability in the sea-ice cover of the eastern Bering Sea
Interannual variability in air temperatures, ice cover, and surface winds in the Bering Sea generally are in phase with each other, whereas sea-surface temperatures (SST) tend to lag these variables by 1-3 months. These Bering Sea time-series
are significantly correlated with the Southern Oscillation Index (SOI) time-series (an indicator of ENSO events) when the Bering sea data are lagged behind the SOI for up to 18 months. The correlations suggest that warming in the Bering Sea follows negative
anomalies in the SOI (i.e., El Nino events). Cooling in the Bering Sea tends to follow positive anomalies (i.e., precursors of El Ninos) in the SOI.

1953-1988 oceanographic data files on the China Seas prepared by the National Marine Data, China, and the 1953-1982 reports of seasurface monthly mean temperature in the East China Sea by the Meteorological Agency, Japan, were used to calculate
the digital characteristics of frequency distribution of sea and air temperature in 153 areas in the China seas. Principal factor analysis and fuzzy cluster ISODATA were used to divide the China hydroclimatic area into 3 climatic zones including 10 climatic
