摘要

The present study was carried out at Hamam Pharaon hot springs, on the eastern shore of Gulf of Suez. These springs are characterized by outflow of hot gas bubbles and hydrothermal seepage to the surrounding marine environment. The study compares physicochemical parameters of water and sediment of hot springs versus the surrounding marine environment. Also, assesses marine benthic communities and associated fishes of the target area versus reference stations. Temperature, salinity, pH, oxygen concentration were measured at both habitats. Hot (66?°C), slightly acidic (pH 6.3), brackish water (9%), with low level of oxygen content (0.2 mg L-1) usually emerges from these hot springs. Then usually seeps through fine sands to adjacent sea water of Gulf of Suez. Belt transects perpendicular to the shore were established at the study area versus two reference stations (away from hot springs) to the north and south of the target area. The benthic biota and associated fishes were quantitatively assessed by snorkeling and SCUBA diving. The results showed that the pattern of fluctuation in temperature, salinity, pH and oxygen content in sea water near shore (around hot springs) was not significantly different from water at the offshore end of transects and/or reference stations (with temperature 25?°C, salinity of 43%, pH of 7.6 and oxygen content of 5.5 mg L-1). The recorded biodiversity was low consisted of seaweeds which were dominated by floating Sargassum lantifolium and Padina pavonica covering 30% of small rocks patches near shore, invertebrates with dominant species of echinoderms, which were sea heart Lovenia elongata and sand dollar Echinodiscus bisperforatus and fishes, which represented by Arabian pinfish Diplodus noct , mullet Liza carinata , bristly buffer Arothron hispidus and slender lizardfish Saurida gracilis . According to these results, it could be concluded that seepage of hot springs of Hamam Pharaon to the marine environment does not affect the physicochemical parameters (temperature, salinity, pH and oxygen concentration) and/or the ecology of benthic communities and associated fishes of the surrounding marine environment receiving their outflows.
