The objective of this study is to understand the calcareous nannoplankton response to past environmental changes in the Strait of Hormuz during the Holocene. Calcareous nannoplankton is well abundant in the living phytoplankton community and a key component of the marine sediments. Due to its distinct reaction to environment changes and its good preservation potential, it is well suited for p...

Analysis of the shape properties of fish otolith is one way to identify stocks of different species in the marine environment. Length, width, area, perimeter, form factor, aspect ratio, roundness, circularity, ellipticity and rectangularity analyses of otoliths were undertaken to assess patterns of spatial and temporal stock structure of a wide-ranging fish, the Arabian yellow fin sea bream Aca...

The present study was conducted using geometric morphometric analysis of otolith to discriminate stocks of the predominant species of genus Acanthopagrus in the west and east of Strait of Hormuz. Samples were taken from 5 regions in the Persian Gulf and Oman Sea from March 2016 to March 2018. The 145-otolith samples were obtained from the Arabian yellowfin sea bream (Acanthopagrus arabicus). Th...

Multi-path interference due to boundary reflection in shallow water acoustic communication poses a major obstacle to reliable and high-speed underwater communication system. In this study, initially 3D variations of field data such as sound speed, temperature and salinity in horizontal transects of the Strait of Hormuz were analyzed using the ROPME data. Later, data on typical sound speed ...

pollutions. Recently, both Persian Gulf and Gulf of Oman are experiencing several types of pollution including oil spills and heavy metal pollutions as well as Harmful Algal Bloom (HAB) caused by biological and environmental changes. Theiroccurrence of the red tide or harmful algal bloom during fall and winter 2008-2009 caused numerous unknown factors in the Strait of Hormuz, Persian Gulf and G...

Observations in the Strait of Hormuz (26.26°N. 56.08°E) during 1997-98 showed substantial velocity fluctuations, accompanied by episodic changes in the salinity outflow events with amplitude varying between 1 and 2 psu on time scales of several days to a few weeks. These events arc characterized by a rapid increase in salinity followed by an abrupt decline. The mechanisms behind these strong pu...
