The representatives of the genus Ampelisca Krøyer, 1842 collected during the PGGOOS expedition (the Persian Gulf and Gulf of Oman Oceanographic Study) were studied. The species Ampelisca persicus sp. nov., Ampelisca lowryi sp. nov. and Ampelisca linearis sp. nov. were described. A redescription of Ampelisca cyclops Walker, 1904 was prepared based on material of the western part of the Indian Ocean. The differences between this and other records of A. cyclops were studied.

A New Species

Published records on the Ophiuroidea fauna of the Persian Gulf and Gulf of Oman are scattered in difficult to access journals and books. This study presents a compilation of all published records, complemented with data from new samples. Distribution, habitat and depth in the study area, as well as known Indian Ocean distributions, are included. The taxonomic status of all species was evaluated, critical comments were added as applicable, and several previous records were reassigned to other species. Ophiocoma erinaceus was removed from the fauna of the Persian Gulf and Gulf of Oman, because the only published record was instead Ophiocoma schoenleinii. Previous studies assumed that 46 species of brittle star were known from the study area, but only 38 species were confirmed by this re-assessment, including two new records (Ophiothrix (Ophiothrix) foveolata and Ophiocomella sexradia). Diagnostic features are supplied for difficult to distinguish species. Five species (Macrophiothrix elongata, Amphiura fasciata, Amphiura (Ophiopeltis) hexactis, Amphioplus echinulatus, and Amphioplus seminudus) are so far worldwide known only from the Persian Gulf area. A hexamerous, fissiparous species of Ophiothela that does not concur with any known species was found and may represent a new species. All newly collected species are illustrated with photographs.

Strike Slip Movement

Bathymetric and magnetic measurements at a 10-mile line spacing across the mouth of the Gulf of Oman have made a substantial contribution to knowledge of the area. A northeast-southwest alinement of bathymetric features, the presence of many fault scarps and the occurrence of elongated weakly magnetized seamounts similar to others farther south suggest that the Murray Ridge is continuous with the Owen fracture zone and support the idea that both are loci of strike-slip movement.

First Time

The family Macrophthalmidae Dana, 1851, is one of the best represented brachyuran groups in intertidal habitats in the Persian Gulf. Nine species from two subfamilies are reported from the gulf and the adjacent Gulf of Oman, mainly inhabiting intertidal soft substrates. The subfamily Ilyograpsinae Števcic, 2005, is represented by Ilyograpsus rhizophorae Barnard, 1950, erroneously recorded as I. paludicola (Rathbun, 1909). Eight species of the subfamily Macrophthalminae Dana, 1851, have been recorded from the area, all belonging to Macrophthalmus Desmarest, 1823. Of these, M. sinuspersici Naderloo & Türkay, 2010, has recently been described and is the only species of the genus occurring on rocky shores. Macrophthalmus graeffei A. Milne-Edwards, 1873, occurs in subtidal water and is hereby recorded for the first time from the northern Indian Ocean. The remaining six species, M. dentipes Lucas, 1836, M. depressus Rüppell, 1830, M. grandidieri A. Milne-Edwards, 1867, M. laevis A. Milne-Edwards, 1867, M. serenei Takeda & Komai, 1991, and M. sulcatus H. Milne-Edwards, 1852, are important elements of the intertidal soft bottom communities. An identification key for the genus Macrophthalmus in the area is provided, and the geographical distribution of the family is briefly discussed.

AbstractSatellite observations are used to establish the dominant magnitudes, scales, and mechanisms of intraseasonal variability in ocean dynamic sea level () in the Persian Gulf over 2002–2015. Empirical orthogonal function (EOF) analysis applied to altimetry data reveals a basin-wide, single-signed intraseasonal fluctuation that contributes importantly to variance in the Persian Gulf at monthly to decadal timescales. An EOF analysis of Gravity Recovery and Climate Experiment (GRACE) observations over the same period returns a similar large-scale mode of intraseasonal variability, suggesting that the basin-wide intraseasonal variation has a predominantly barotropic nature. A linear barotropic theory is developed to interpret the data. The theory represents Persian-Gulf-average () in terms of local freshwater flux, barometric pressure, and wind stress forcing, as well as at the boundary in the Gulf of Oman. The theory is tested using a multiple linear regression with these freshwater flux, barometric pressure, wind stress, and boundary quantities as input, and as output. The regression explains 70%±79% (95% confidence interval) of the intraseasonal variance. Numerical values of regression coefficients computed empirically from the data are consistent with theoretical expectations from first principles. Results point to a substantial non-isostatic response to surface loading. The Gulf of Oman boundary condition shows lagged correlation with upstream along the Indian Subcontinent, Maritime Continent, and equatorial Indian Ocean, suggesting a large-scale Indian-Ocean influence on intraseasonal variation mediated by coastal and equatorial waves, and hinting at potential predictability. This study highlights the value of GRACE for understanding sea level in an understudied marginal sea.
