The Arabian Sea is a region of elevated productivity with the highest globally recorded fluxes of particulate organic matter (POM) to the deep ocean, providing an abundant food source for fauna at the seafloor. However, benthic communities are also strongly influenced by an intense oxygen minimum zone (OMZ), which impinges on the continental slope from 100 to 1000 m water depth. We compared the...

Turbinaria foliosa sp. nov. is described on the basis of several collections made from Dhofar, Sultanate of Oman. The new species is known only from southern Oman, a region of the northern Arabian Sea that is strongly impacted by the upwelling from the summertime monsoon. It is distinguished from other species of the genus by the shape of the leaves and by their loose, non-congested arrangement...

A new species of the red algal genus Gelidium, G. omanense M.J. Wynne, is described from the Sultanate of Oman, northern Arabian Sea. This species is a very commonly occurring eulittoral seaweed on the Omani coast, essentially one of the dominant species during the summertime southwest monsoon on exposed rocky shores. Its distribution is from Dhofar (southern Oman) in the west to Masirah Island...

Despite the numerous studies proposing early human population expansions from Africa into Arabia during the Late Pleistocene, no archaeological sites have yet been discovered in Arabia that resemble a specific African industry, which would indicate demographic exchange across the Red Sea. Here we report the discovery of a buried site and more than 100 new surface scatters in the Dhofar region o...

The cardinalfishes Archamia bilineata and A. pallida were originally described from a small number of specimens collected in the Gulf of Aqaba, Red Sea and Oman, respectively. Both species are re-described using specimens collected recently in Yemen and Kenya, including the first known adult of A. pallida. These new collections increased the geographical range of both species considerably. Diff...

the growth parameters, mortality rates and exploitation population dynamic parameters and exploitation rate of psettodes erumei were assessed between july 2010 to june 2011 using length frequency analysis. the data were collected from landing sites of jask, bandar abass, kong and qeshm hormozgan province waters. using total weight (w) and total length (tl) data, the length- weight relationship ...

Total marine fisheries catches by Oman were estimated from 1950 to 2010, including large-scale and smallscale commercial catches, subsistence, and recreational catches, as well as major discards. Reconstructed total catches increased from around 53,600 t∙year-1 in the 1950s to almost 200,000 t·year-1 in the 2000s. This estimated catch is 1.3 times the landings reported by the FAO on behalf of O...

sea level variations in the persian gulf, the oman sea and the north of the arabian sea have been investigated. for this purpose, 365 daily satellite images provided by the topex/poseidon (t/p) and jason-1 satellites were processed. programming in matlab software environment was also carried out for some parts of image processing. the results of this research reveal that water level fluctuation...
