As potassium, chloride and water traverse cell membranes, the cells of stenohaline marine invertebrates should swell if exposed to sea water mixed with an isosmotic KCl solution as they do when exposed to sea water diluted with water. To test this hypothesis respiratory tree fragments of the holothurian Isostichopus badionotus were exposed to five isosmotic media prepared by mixing artificial s...

The Southern Ocean is an important part of the global climate system, but its complex coupled nature makes both its present state and its response to projected future climate forcing difficult to model. Clear trends in wind, sea-ice extent and ocean properties emerged from multi-model intercomparison in the Coupled Model Intercomparison Project phase 3 (CMIP3). Here, we review recent analyses o...

Various researchers have reported and described the adverse effects of saltwater ingression in coastal zones of different parts of world like Italy, Japan, Greek islands, Oman, Nigeria, Atlanta Coast USA, Turkey, Netherlands, Catalonia and Sardinia and various coastal areas of India [1-35]. India has long coastal line of 5700 km. The east coast (Coromandel Coast) extended from West Bengal to Ka...

Mandt's black guillemot (Cepphus grylle mandtii) is one of the few seabirds associated in all seasons with Arctic sea ice, a habitat that is changing rapidly. Recent decreases in summer ice have reduced breeding success and colony size of this species in Arctic Alaska. Little is known about the species' movements and distribution during the nine month non-breeding period (September-May), when c...

Carbon, non-exchangeable hydrogen, and oxygen isotope ratios of cellulose of Avicennia germinans and Rkizophora mangle plants hydroponically grown under different salinities (0, 18, 45% sea water, but with irrigation waters having the same isotopic ratios) were measured to determine the possibility of using isotopic ratios of plant tissues as biological recorders of sea level rise. There was a ...

Using molecular techniques, a longitudinal study was conducted with the aims at identifying the seasonal difference of Cryptosporidium contamination in surface water as well as analyzing the potential sources based on species information. One hundred forty-four water samples were collected, 72 samples from the Chao Phraya River, Thailand, collected in the summer, rainy and cool seasons and 72 s...

The main aquifer of the Llobregat delta (Barcelona, Spain) has been affected by seawater intrusion since the 1960s. The Catalan Water Agency (ACA) has sponsored the construction of a positive hydraulic barrier in order to stop the progress of seawater intrusion advance due to the intensive aquifer development. The hydraulic barrier consists of 15 wells into which highly treated reclaimed water ...

During recent years, the use of marine outfalls for the disposal of sanitary and industrial wastes has increased greatly and information regarding the fate of bacteria in sea water has assumed public health significance. Unpolluted sea water does not contain large numbers of bacteria, and bacteria which enterthe oceans by way of land drainage and sewage outfalls die quickly. The numbers of bact...
