Sea surface temperature is one of the most effective physical parameters that affects the health of coral reefs communities.High frequency of the bleaching phenomenon has extensively occurred in the Persian Gulf in the recent years due to the increase in temperature and increased changes in the sea surface temperature (SST) resulting in great mortality in the coral communities. The aim of this ...
sea surface topography (sst) by definition is the separation between the geoid and the mean sea level (msl). the separation between the geoid and msl is caused by various non-gravitational physical effects. if determination of the geoid as the zero point of the height systems from the tide gauge observation be the goal, it is necessary that the affect of the physical effect be precisely compute...
ABSTRACT Background : Natural uranium exists in earth crust and seawater. The concentration of uranium might increase by human manipulation or geological changes. The aim of this study was to verify susceptibility of laser flourimetry method to determine the uranium concentration in Caspian Sea and Persian Gulf water. Materials and Methods : Laser flourimetric method was used to determine...
the present research was conducted to accomplish two purposes. firstly, it aimed to explore and describe schematic structure or what halliday and hassan (1989, p.64) have called “generic structure potential” (gsp) of american english, iranian persian and iranian english newspaper editorials within systemic functional linguistics. secondly, a quantitative cross-comparison was made to investigate...
این مطالعه در سه محل از سواحل بندر لنگه در جنوب ایران، در سواحل شمالی خلیج فارس انجام شد . 119 گونه از جلبکهای جمع آوری و شناسایی شده منطقه که شامل 29 گونه جلبک سبز (2 گونه گزارش جدید)، 31 گونه جلبک قهوه ای (4 گونه گزارش جدید) و 59 گونه قرمز (2 گونه گزارش جدید) می باشد معرفی می گردد.
Scombermorus commerson is one of the most important and commercial species in the Persian Gulf and Oman Sea. In order to adopt the responsible fishing patterns, it was necessary to estimate population dynamic parameters. Samples were collected randomly from five major traditional fish-landing sites in Chabahar, Jask, Bandar Abbas, Bandar Lengeh and Parsian in the north of the Persian Gulf ...
This paper addresses how to assess the performance of refractivity-from-clutter (RFC) techniques in different regions of the world with varying duct strengths and statistics. The performance of evaporation duct estimation is investigated in littoral zones such as the North Sea, Wallops Island, Coast of California, Mediterranean, Persian Gulf, and Coast of Brazil. The effects of the radar freque...
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...
Coral reefs are in rapid decline on a global scale due to human activities and a changing climate. Shallow water reefs depend on the obligatory symbiosis between the habitat forming coral host and its algal symbiont from the genus Symbiodinium (zooxanthellae). This association is highly sensitive to thermal perturbations and temperatures as little as 1°C above the average summer maxima can caus...
six species of sargassum c. agardh (sargassaceae) with compressed primary branches, including: s. binderi sonder, s. aquifolium (turner)c. agardh, s. oligocystum montagne, s. swartzii (turner)c. agardh, s. crassifolium j. agardh and s. cristaefolium c. a. agardh, were identified in the persian gulf and oman sea coasts, among which s. binderi is reported as newly recorded species in iran for the...
