Tides are the main type of sea level variability in the world oceans. However, oceanic tides penetrate weakly, or do not penetrate at all, into enclosed basins such as the Baltic, Black, and Caspian seas. Consequently, only directly forced tides are formed in these basins. Long observation time series (up to 123 years in the Baltic Sea and 38 years in the Black and Caspian seas) at numerous sta...

twenty water samples from a river system in southern caspian sea basin werecollected and analyzed for physicochemical parameters and metals (cu, zn, as, cd, pb, ni andmn). in order to evaluate the risk potential of metal pollution in river water, use of two indicesnamely heavy metal pollution index (hpi) and contamination index (cd) accompanied by clusteranalysis was taken in to consideration. ...

nowadays, a noticeable part of the relations among the states turn around the environment protection. therefore, the right for ever-creasing use of the existing resources of this inland sea cannot be exclusive to any caspian state and the aftermath involves all countries of this basin. in this respect, agreement on political border and boundaries with the caspian sea?s ecosystem is a difficult ...

The worldwide occurrence of complex climate-induced ecological shifts in marine systems is one of the major challenges in sustainable bio-resources management. The occurrence of ecological environment-driven shifts was studied in the Southern Caspian Sea using the "shiftogram" method on available fisheries-related (i.e. commercially important bentho-pelagic fish stocks) ecological and climatic ...

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...

This paper provides information on the geographic distributions of two cyprinid species: Hemiculter leucisculus (Basilewsky, 1855) and Alburnus caeruleus Heckel, 1843, in the world and the entire drainage systems in Iran. The new distribution records were taken from Maroon River (Jarrahi River system) and Chardaval River (Karkheh river system), both in Tigris River basin showing wide and narrow...

Remote measurements of different environmental parameters received during last 30 years are used for the synthesis of a Complex Simulation Model (CSM) describing the combined water regimes of the Aral-Caspian System (ACS) including the consideration of aquatic and climatic natural processes. The problem of stabilizing the sea levels of these two water bodies is modelled and a solution obtained ...

  Random amplified polymorphic DNA (RAPD) markers were used to estimate genetic relationships between two seasonal immigrant forms (namely fall-run and spring-run) of Caspian trout Salmo trutta caspius. In this regard, 62 fin tissue samples were collected from southern parts of the Caspian Sea basin and examined with 16 oligodecamer primers to asses their genetic diversity as well as probable s...
