The Gulf of Aden, although subject to seasonally reversing monsoonal winds, has been previously reported as an oligotrophic basin during summer, with elevated chlorophyll concentrations only occurring during winter due to convective mixing. However, the Sea-Viewing Wide Field-of-View Sensor (SeaWiFS) ocean color data reveal that the Gulf of Aden also exhibits a prominent summer chlorophyll bloo...

introductionmany aspect strongly influence regional climate includes localized surface processes, large-scale patterns, especially mid and upper level tropospheric circulation and many factors control precipitation in the west of iran includes location of emigrate westerly winds systems, jet streams location, humidity flux and topography. upper tropospheric jet stream constitutes a significant ...

The ethyl acetate soluble part of a methanolic extract of the marine green alga Codium iyengarii, collected from the Karachi coast of the Arabian Sea, afforded four new derivatives of glycerol named : codioside A,B,C,D (1-4), a new derivative of frans-phytol named codioester (5) and rrans-phytol (6). The structures of 1-5 were elucidated with the aid of acid hydrolysis, methylation, GC-MS, and ...

Food and feeding habits of the Santer Seabream Cheimerius nufar were studied from the Arabian Sea coast of Oman for two years during April 2005-March 2007. The stomach contents consisted of substantial quantities of semi-digested matter and identifiable items like sardines, crab, squid, cuttlefish and other crustacean remains indicating the fish is an active carnivore. There was not much variat...

A new species of the copepod genus Tortanus (Atortus) (Copepoda: Calanoida), T. (A.) insularis, is described from the coastal region of Rodrigues Island, Mauritius, an isolated island in the south-western Indian Ocean. This new species can be assigned to an Indian faunal element, the recticauda species group, in the Indo-West Paci¢c recticauda species complex. It exhibits the closest relationsh...

A new paramicrolaimid nematode, Paramicrolaimus damodarani sp. nov., is described based on specimens from the continental shelf (95 m) of the south eastern Arabian Sea. Paramicrolaimus damodarani sp. nov. differs from other known species of the genus in having a smaller body size, form of the spicular apparatus, presence of 7 cuticularised protruding precloacal supplements and a strongly cuticu...

A new fossiliferous locality is discovered from the upper Eocene Aydim Formation, in Dhofar, Southern Sultanate of Oman. A left ulna of rsinoitherium is described, and cranial and postcranial specimens found in close proximity are referred to the same taxon. The locality is romising for the recovery of additional fossil specimens. Moreover, the presence of Arsinoitherium in Oman is of biogeogra...

My objectives for this ONR project were first to develop an ocean model that can accurately simulate Arabian-Sea mixed-layer variability at diurnal through annual time scales, and then to diagnose the processes that account for this variability in its solutions. I particularly wished to be able to simulate and understand the mixed-layer-thickness record determined from the WHOI mooring data at ...

Two specimens of Argyropelecus gigas and Conocara fiolenti were collected from off the city Salalah on Arabian Sea coasts Oman. The represent first confirmed record species northwestern quadrat Indian Ocean. Meristic morphometric characters match those described for these species.
