the main purpose of this study is the survey of the atmospheric low pressure effects at sea level oscillations in the qeshm channel. for this purpose, the curves of the pressure on the persian gulf and oman sea, during the passing of the atmospheric low pressure system, are extracted across the region. during the time of occurrence of these events, sea level oscillations in the coastal areas of...
This paper investigates and estimates the surface salinity changes of the Persian Gulf using the FVCOM numerical model. Sea level salinity (SSS) is one of the important parameters in oceanographic studies. The Persian Gulf is a semi-closed and shallow sea, which is high in the Persian Gulf due to its low rainfall, salinity and water density. One of the limitations of this region is the lack of ...
Extracting the main cyclic fluctuations from sea level changes of the Persian Gulf and Oman Sea is vital for understanding the behavior of tides and isolating non-tidal impacts such as those related to climate and changes in the ocean-sea circulations. This study compares two spectral analysis methods including: Least Squares Spectral Analysis (LSSA) and Least Squares Harmonic Estimation (LSHE)...
the age and growth of the persian sturgeon, acipenser persicus, obtained from the iranian coastal waters of the caspian sea, were studied through analysis of the pectoral fin ray section from 180 specimens, ranging in fork length (fl) from 66 to 203 cm. the specimens were obtained from commercial fisheries between october 2008 and june 2010. interpretation of growth bands in the pectoral fin ra...

Small pelagic fishes particularly anchovy (Encrasicholina punctifer) and sardine (Sardinella sindensis) have an important role to support the Iranian fisheries and are distributed along the coastal waters of the Persian Gulf and Oman Sea. Using a logbook on small pelagic fisheries, a GIS-based environmental modeling approach was applied to investigate the presence and abundance of anchovy and s...
the family porcellanidae is a group of crab-shaped anomurans and there are a series of studies on this group in the persian gulf. the first report of porcellanid crabs from the persian gulf was by heller (1861); who referred incidentally to two species of this group in a discussion of crustacea of the red sea.
Several studies on the white sardine: Sardinella albella, have focused on the identification of stock composition and behavior. In this study population genetic structure and historical demography of S. albella along the cost of the Persian Gulf and Sea of Oman were investigated with a 500-bp segment of mt-DNA control region. In total 40 samples were collected from 3 locations: Jask in Sea of O...
Stylophora pistillata is a widely used coral "lab-rat" species with highly variable morphology and a broad biogeographic range (Red Sea to western central Pacific). Here we show, by analysing Cytochorme Oxidase I sequences, from 241 samples across this range, that this taxon in fact comprises four deeply divergent clades corresponding to the Pacific-Western Australia, Chagos-Madagascar-South Af...
Introduction Given the diverse characteristics of Iranchr('39')s geographical area, we know that the diversity of Iranchr('39')s natural landscape is not limited to the lowland and highland areas. Evidence suggests that large bodies of water in northern and southern Iran and its surrounding lands have long been one of the most attractive niches for human societies. Some misconceptions have ...
