In this study is simulation of role of topography in thickness and Inland penetration of sea-breeze in southern coast of the Caspian Sea. The RegCM4 as a regional scale climate model coupled with a lake model and also the reanalysis data of NCEP / NCAR used to determine of the initial conditions of the model. The model was run during the peak of sea breeze on the southern coast of the Caspian S...
although the southern caspian sea basin (scsb) fish fauna has been studied for more than 200 years, new species continue to be discovered, reported and renamed. here we take the opportunity to provide a new and updated checklist of the fishes of the southern caspian sea basin. the list is based on historical literature records and taxon occurrence data obtained from natural history collections ...
The Southern Caspian Sea ophiolite complex (SCO) is one of the Late Cretaceous discontinuous oceanic lithosphere remnants in northern Iran. These complex is almost a complete sequence from bottom to top, ultramafic cumulates, layered gabbros, isotropic gabbros, dike complex and basaltic lavas which is covered by Late Cretaceous (Companion- maaestirchtian) pelagic limestone. Crustal ultramafic c...
Genetic diversity is a key component of ecosystems. The aim of the present study was to evaluate the genetic diversity of Iranian native honeybee colonies (Apis mellifera meda L.) located in the northern region. Colonies from 24 locations have been analyzed using microsatellite markers. Samples were collected from Caspian Sea southern area (north of Iran). Six microsatellite markers (A28, A29, ...
the southern coasts of caspian sea is subjected to synoptic/mesoscale weather systemsranging from locally enhanced sea breeze formation and small local front systems to synoptic scale cyclones.this study presents climatology of cyclones over the southern coasts of caspian sea covering a ten year period1996-2005. altogether 57 cyclones were formed during the ten year period. anoticeable seasonal...
Caspian kutum, Rutilus frisii Kamensky 1901, is a commercially important fish species in the southern part of the Caspian Sea. All of the metal entered in the Caspian Sea. The pollution of this metal cause To create environmental problem. To address the issue, some 51 R. frisii specimens were caught at five different fishing regions (including Astara, Anzali, Kiashahr,) of the southern shorelin...
The study of interaction between fish cage culture and sediment population dynamics heterotrophic bacteria in the southern Caspian Sea (Nowshahr region)
Welcome to our international conference on rapid sea-level change. While concern about sea-level rise is global, our host country the Islamic Republic of Iran and the neighbouring Caspian countries have a concern of their own. Here, Caspian sea level rose a hundred times as fast as in the world’s oceans. Whereas oceanic sealevel rose 13 centimeter during the whole twentieth century, the Caspian...

introduction one of the important events that usually occur in seas and large water bodies’ concurrent with the change of season is the growth and species increase of phytoplankton. in the natural environment, this event does not result in imbalances of water ecosystems. however, pollution caused by human activities results in excessive growth and reproduction of phytoplankton and other opportu...
