OCEAN THERMAL ENERGY CONVERSION Abstract Ocean Thermal Energy Conversion (OTEC)‚ to me‚ is the developing worlds answer to OPEC (Organization of Petroleum Exporting Countries). We will no longer have to depend on oil supplies from other countries. OTEC is an efficient‚ clean process‚ which utilizes the difference in temperatures between the oceans surface and its depths to produce energy. The ocean thermal energy conversion process works something like a refrigerator in reverse. The

The primary challenge of inhabiting a high salinity environment is balancing osmotic pressure. Since these environments contain high salt concentrations‚ water from the cells of organisms spontaneously diffuses out of the cytoplasm in order to restore osmotic balance. This leaves cells dehydrated and thus‚ eventually causes cell death. In order to ameliorate this predicament‚ halophiles use one of two unique strategies that function to increase the osmolarity of the cell‚ both of which as illustrated

effect the environment. Abiotic and biotic factors combine together to create an eco system. An ecosystem is a community of living and non living things combined together carefully. Abiotic factors include sunlight‚ temperature‚ water‚ turbidity‚ salinity‚ pH‚ nitrides D.O. These factors have a major effect on the biotic factor in the eco system. Turbidity Turbidity is the measurement of the clearness of the water. The major determination that can affect the turbidity of the waterways is human

The effect of salt concentration on grass growth Abstract Our aim was to test the effect of different salinities on the growth of plants which what we did was measured different amounts of salt dissolved into 2 litres of water‚ watered the plant once with the salt water then for 9 days with pure ware. I found with my investigation that the less the salt‚ the more the growth of the plant. My aim was achieved by measuring the 5 fastest geminating (out of 20) and to measure the differences in growth

Currently‚ our planet is going through a series of significant climate events that is potentially leaving an impact. Global warming has been at the center of creating destructive climate change. By increasing the amounts of greenhouse gases‚ humans are creating an environment with hotter temperatures‚ melting ice caps‚ and rising sea levels. To add on‚ scientists are now worried that humans are potentially destroying the oceans by creating an acidic environment in the water. The acidic environment

apart causing deep cracks in the floor of the ocean. Seawater seeps into these cracks and is heated by the molten rock below the Earth’s crust. As the water heats‚ chemical reaction begin to occur‚ and oxygen and minerals are removed from the water. As it goes deeper and gets hotter‚ certain metals and sulfur dissolve into it‚ and then the fluid begins to rise. It gushes back to the ocean floor‚ meeting with the near-freezing‚ oxygen-rick seawater‚ causing more chemical

Sundarban : An Overview Sundarbans National Park Sundarbans National Park covers 10‚000 km2 of land and water (more than half of it in India‚ the rest in Bangladesh) in the Ganges delta. It contains the world’s largest area of mangrove forests. A number of rare or endangered species live in the park‚ including tigers‚ aquatic mammals‚ birds and reptiles Outstanding Universal Value Brief synthesis: The Sundarban contain the world’s largest mangrove forests and one of the most biologically productive
