This review presents the spatio-temporal distribution of petroleum hydrocarbons including total petroleum hydrocarbon (TPH), total organic carbon (TOC), total aliphatics, unresolved complex mixture (UCM), polycyclic aromatic hydrocarbons (PAHs), and total aromatic hydrocarbons in marine sediments of the Gulf (Iraq, Iran, Kuwait, Saudi Arabia, Bahra...

The assessment here includes data on levels of contaminants (petroleum hydrocarbons and heavy metals) in sediments and biomonitor organisms, including the eulittoral rock oyster Saccostrea cucullata and subtidal biomonitors, the barnacle Balanus trigonus and the antipatharian coral Antipathes sp., at harbours, marinas, terminals and large ports alo...

Historical data were used to estimate interannual tendencies for the Sea of Oman over the past 50 years. Declining trends were shown for the atmospheric surface level pressure in the region affected by the Siberian High atmospheric anomaly, the zonal component of wind speed, concentration of nitrates, biomass of diatoms and sardine landings. Change...

A persistence of hypoxia is a common feature for the Sea of Oman, and the western Arabian Sea. By using historical data complemented by ongoing measurements, the relationship between the frequency of harmful algal blooms, fish kill incidents, and oxygen depletions, was investigated. In the Sea of Oman, the seasonal pattern exhibited a tendency of f...

Worldwide blooms of the green alga Trichosolen have been reported on damaged coral reefs following catastrophic events. However, the global distribution of Trichosolen and the factors triggering such blooms remained elusive because of a paucity of occurrence records. This study presents a presence-only niche modelling approach to map the potential...

The cyanobacterial layer (1-3 mm) of microbial mats of Wadi Muqshin, Sultanate of Oman, in hypersaline continental pools near the Empty Quarter desert were analyzed for cyanobacterial diversity, pigments composition and antibacterial and quorum sensing inhibition activities at the microbial community level. The salinity of the ponds reached up to 7...

Sediments can accumulate various pollutants and are widely used for environmental monitoring of human impact. The central purpose of this study was to examine the levels of eight heavy metals in subtidal sediments in the vicinity of two thermal power/desalination plants in Oman: (1) the Barka power/desalination plant and (2) the Al-Ghubrah power/de...

The sedimentary characteristics of shell beds within an interpreted tsunami deposit from Sur Lagoon, Oman were examined using shell taphonomy and high-resolution particle-size analysis. The tsunami bed was deposited by the 28 November, 1945 tsunami generated by the Makran subduction zone. Q-mode cluster analysis of particle-size data was evaluated...

Digestive tract contents of stranded green turtles (Chelonia mydas) from Ra's Al Hadd area, Oman, were examined. In decreasing order of importance, the food items (dry weight) comprised 19 taxa of algae (49%), 22 taxa of animal matter (26%), 2 seagrasses (15%), litter (7%), and substrate (3%).

The paper reports studies on benthic microbial dome‐shaped mats found in hypersaline desert pools in Wadi Muqshin, southern Oman, and details the hydrogeological conditions of the pools, including water quality and recharge features. The upper 1 cm layers of these microbial mats are dominated by cyanobacteria, a phototrophic purple sulphur bacteriu...

"MRMEWR (2003) Status Of the Marine Environment Report (SOMER) - Sultanate of Oman Country Report to UNEP Regional Seas Programme / ROPME Sea Area (RSA).

A total of 74 new records of benthic marine algae have been compiled for the flora of the Sultanate of Oman. These records include 34 taxa of Rhodophyta, 16 taxa of Phaeophyta, and 24 taxa of Chlorophyta.

Distribution, abundance, and biomass data for seagrass communities at several locations on the coast of Oman are presented. The main study site was on the western side of Masirah Island on the Arabian Sea coast of Oman. This area is an important feeding ground for the green turtle, Chelonia mydas L., and it is affected by upwelling of low temperatu...

Measurements of the biomass of deepwater rice plants at sites on the three major floodplains in Bangladesh (Ganges, Jamuna, Meghna) with and without fertilizer treatment were made from shortly before the arrival of flood water (June) until it was receding (mid-October). There was usually an approximately linear increase in biomass per unit area wit...

The effects of rat damage on deepwater rice (DWR) yields were evaluated in 1987 and 1988 by the use of exclusion fences in the Bangladesh Rice Research Institute's DWR site at Rajbari, Gazipur. Bandicota indica (Bechstein) and B. bengalensis (Gray and Hardwicke) started cutting the elongating stems from August and continued until harvest (November)...

For the first time seagrass rehabilitation was attempted in a tropical nation, Jamaica. Repairs to a variety of developmental impact types were attempted with test plots: dredge and fill, bauxite and oil spills, channelization, urban run-off, urban sewage, river bulkheading, jetty construction and artificial beach, industrial lagoons, saline lagoon...

Seventy-four villages in eastern Sierra Leone, West Africa, many having a recently developed rice swamp, were surveyed for the presence of schistosomiasis and onchocerciasis, and their vectors. Prevalence rates for Schistosoma haematobium and S. mansoni were low, although the infections were widespread. There is some evidence that S. mansoni is ext...

A study has been made of the concentrations of Zn, Cd and Pb in the aquatic liverwort Scapania undulata in streams and rivers in England, France, Germany and Ireland. Brief general observations are included to help the use of this plant as an environmental monitor. Many of the sites are influenced by past or present mining activities and provide a...

Coral reefs of north Jamaica, normally sheltered, were severely damaged by Hurricane Allen, the strongest Caribbean hurricane of this century. Immediate studies were made at Discovery Bay, where reef populations were already known in some detail. Data are presented to show how damage varied with the position and orientation of the substraturn and w...

Comparative data are presented of the biomass of Laminaria ochroleuca and L. hyperborea at several off-shore sites in Normandy and Brittany and of the growth of these species in a mixed stand between 5 and 18 metres below Mean Low Water at Port Levi near Cherbourg. All these sites are characterised by strong current surges and large tidal ranges. B...

(1) Limitations on the growth of the two most important submerged macrophytes in Loch Leven, Potamogeton filiformis and P. pectinatus, were shown to result from wave action and from grazing by waterfowl. Wave action operates directly, by reducing plant biomass in exposed situations, and indirectly, by producing coarser, more nutrient-poor sediments...

Twelve species of submerged macrophytes occur now in Loch Leven as compared with twenty-three in 1910. Only four are common: Chara aspera, Nitella opaca, Potamogeton filiformis and Zannichellia palustris. The more recently recorded algae and macrophytes such as Cladophora sp., Enteromorpha sp., Potamogeton filiformis and Zannichellia palustris all...

A quantitative survey of sublittoral marine organisms was carried out in polluted and unpolluted waters near Marseille (France). Samples from rocky substrates indicate that organic pollution effects have not decreased since earlier surveys.Studies of beds of Posidonia oceanica, the dominant Mediterranean sea grass, show that its biomass is low in t...

Biomass and productivity data for Laminaria hyperborea (Gunn.) Fosl. on the west coast of Scotland are presented. SCUBA diving techniques were used to collect the data which indicate higher values of the biomass than do data from spring grab collections from the same region. The mean biomass values were 20.4 kg fresh weight/m2 at 3 m and 7.7 kg/m2...

Synopsis The distribution and production of submerged macrophytes in Loch Leven has been investigated using drag-rake surveys and biomass measurements. Survey data suggest that changes in the species diversity of the loch have occurred since the earlier records. There appears to have been a decline in some species with an increase in others. In gen...

Divers were tested on three aspects of geographical orientation on land and under water. (1) They traveled blindfold around two sides of a triangle and then attempted to return without guidance to the starting post. On land, subjects walked in a straight line for about the right distance, but tended to turn outside the triangle. Under water, they t...
