Observations of the Caspian Sea during August-September 1995 are used to develop a three-dimensional numerical model to be used in calculating temperature and current. The model has variable grid resolution and horizontal smoothing that filters out small scale vertical motion. Data from the meteorological buoy network on the Caspian Sea are combined with routine observations at first-order syno...

abstract: after the collapse of the soviet :union:, and the geopolitical changes in the region, which caused emergence of four new states, the outlook to the caspian sea and it's issues have changed. dealing with numerouse oil contracts with multinational companies and the entrance of transnational states and organizations, aggrevated the political and economic competitions and increased t...

the southern shores of caspian sea is subjected to several atmospheric factors due to its geographical position. north atlantic oscillation(nao) one of the effective phenomenon's affects the most part of hemisphere included caspian sea. in this research negative and positive phases of nao considered with variability of temperature and precipitation of southern shores of caspian sea in a 30...

  This study was carried out to investigate the occurrence of potentially pathogenic species of vibrio in sea water and estuarine environments of the Caspian Sea in the Golestan province of Iran. A total of 127 water samples from coastal waters as well as from river and estuaries were collected and analyzed by culture, during April and September 2001. Following prompt centrifugation, the resusp...

Caspian sea is a land–locked brackish water lake where zoologically characterized by various aquatic animals aquatic animals and different commercially important fish species Shariati [15]. The fishes in the Caspian Sea and its watershed areas include 78 species, and 49 subspecies which belong to 16 fish family. The bulk of Caspian Sea fishes are anadromos and the major commercially important f...

in order to determine the synoptic pattern of heavy and extreme precipitations on the southern coast of the caspian sea, precipitation characteristics of the caspian region were investigated by the use of eight synoptic stations data. considering the percentage thresholds, the days with heavy and extreme precipitations were determined for a 10 year period (1994-2003). since more than 75% of day...
