The rapid rise of Caspian Sea water level (about 2.25 meters since 1978) has caused much concern to all five surrounding countries, primarily because flooding has destroyed or damaged buildings and other engineering structures, roads, beaches and farm lands in the coastal zone. Given that climate, and more specifically climate change, is a primary factor influencing oscillations in Caspian Sea ...

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 ...

We present here the findings from a study of the microbiome of the southern basin of the Caspian Sea, the largest water body on Earth disconnected from any ocean and a brackish inland sea. By high-throughput metagenomics, we were able to reconstruct the genomes of representative microbes. The gross community structure (at the phylum level) was different from the structure of typical marine and ...

Extraction and transportation of oil in the Sea are one of the pollution sources in the Seawater. Caspian Sea contains about 100000 million barrels of oil. It also contains over 35000 millions cubic meter of flue gas. Daily extractions of crude oil and gas and transportation of them are the main pollution sources of the Caspian Sea. Many truck to carry goods and oil tankers to carry oil from po...

in the present investigation flocculation of dissolved cu, zn, pb, ni and mn in a series of mixtures with salinities ranging from 1.5 to 9.5% during mixing of talar river water with the caspian sea water was studied. the flocculation trend of zn (87.22%) >mn (45.31%) >pb (39.09%) >cu (36.58%)>ni (12.70%) indicates that cu, zn, pb and mn have non-conservative behavior and ni has relatively conse...

The Caspian Sea is the world’s largest inland sea. Physiographically it is unique. It is the most productive body of water in the world1 and the only one that preserves the geno-fund of the sturgeon, the source of almost all the black caviar produced. About 10 million people live around the Caspian Sea and the occupations of many of them are connected with the sea, and first of all with fishing...

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...

1.1 Caspian Sea The complex history of the Caspian Sea formation has lead to a variety of different habitats. Like Australia, the Caspian Sea became isolated thousands of years ago (Plate 1). This isolation led to the speciation of many rare animals in particular the sturgeon. The Caspian Sea is the biggest enclosed body of water on Earth, having an even larger area than that of the American Gr...

The experiments with Beroe ovata showed that this ctenophore can survive and reproduce in the Caspian Sea water, though at far lower rate than in the Black Sea; larval growth in the Caspian Sea water was also slower and mortality higher. Maximum fecundity of 2210 and 240 eggs recorded in laboratories of Turkey and Iran, respectively. About 34 to 100% of eggs in the Caspian Sea water could not d...
