Abstract The study presents monthly variations of seawater properties, monitoring water column stability and stratification over the southern shelf of the Caspian Sea which depends on collecting data. Field measurements were carried out during 13 cruises along the southern boundary of the sea. Spatial and temporal distributions of temperature, salinity and density were investigated. Monthl...

Abstract Sea level rise is a worldwide concern as high percentage of the population located in coastal areas. The focus this study impact sea Guadiana Estuary, an estuary Iberian Peninsula formed at interface River and Gulf Cadiz. Estuaries will be impacted by these transitional environments host highly diverse complex marine ecosystems. major consequences are intrusion salt from into fresh wat...

Although Iran's Ghaen Plain provides saffron to much of the world, no regional groundwater quality (GQ) assessment has yet been undertaken. Given the region's potential for saltwater intrusion and heavy metal contamination, it is important to assess the GQ and determine its main probable source of pollution (MPSP). Such knowledge would allow for informed mitigation or elimination of the potenti...

this study was carried out to determine the appropriate size of caspian trout ( salmo caspius kessler, 1877) juveniles for releasing into the rivers that enter south of the caspian sea for stock enhancement, or possibility of cage culture in the caspian sea. a total of 1611 specimens in 4 weight groups of 5, 10, 15 and 20g were exposed to 3 salinity trials which include caspian sea water (11- 1...

The temporal variation of heat budget in the lower layer eastern Ross Sea shelf (ERSS) is crucial for understanding stability ice shelves Sea. In this study, a 6-year (2005–2010) simulation from Southern Ocean State Estimate (SOSE) employed to analyse interannual variations ERSS and controlling mechanisms. results reveal that annual change content study region dominated by horizontal advection ...

Havelockia pegi sp. nov., is here described from shallow waters of the Argentine Sea. This new species is distinctive in the purple colouration of its tentacles, scarcity of body wall ossicles and the presence of rosette-shaped ossicles in both the introvert and the tentacles. It is not closely related to any of its congenors. This is the first record of a true sclerodactylid from Argentina. Th...

IT has been shown by McCutcheon & Lucke (1928) that in glucose solutions isotonic with 40 per cent sea water, the eggs of the sea-urchin Arbada absorb twice as much water as they do from 40 per cent sea water, and that this increased imbibition is prevented by a small concentration of calcium ion in the glucose solution, even in the absence of the other cations of sea water. Pantin (1931a) show...

DOI: 10.17014/ijog.9.2. The phenomenon of land subsidence in Negeri Sila Nusalaut Island was caused by an earthquake Ambon and surrounding areas on September 26, 2019 with the magnitude 6.5. This research had been conducted using a resistivity method dipole-dipole configuration. Land occurred due to seawater intrusion around area. trigger, so soil creep occurred.The purpose this study is obtain...

Around 250 million people live by the coast, less than 5 m above the sea. Changes in sea level affect people through flooding, when water in rivers cannot flow into the ocean because the sea is too high and when seawater surges onto the land during storms. If the sea water finds its way to farms and reservoirs, it can harm our drinking water and our ability to grow crops. Because of this, knowl...

Stable isotope analysis has been used successfully to distinguish between several different ice types in an ice tongue floating on sea water in Antarctica. At one critical location this technique has provided the only means of discriminating unambiguously between glacial ice and fresh-water ice formed from desalinated sea water. This part of the ice tongue is now underlain by a layer of desalte...
