The sandy beach is a harsh, constantly changing environment, explained by the UKMCS (2). This is the oceanic is constantly moving because of the annul in the earths atmosphere (Crawford 4). Along the edge of close coastlines, a commonly found zone is an estuary ( marine Conservation Society (UK) sou-east 1). This is where brackish pisss, an area where freshwater is released and mixed with the oceans flavor water, is created (1). However, even though thither are small amounts of freshwater added, this does non change that the salinity of the ocean is remarkably high.Salt is carried into the ocean by rain, rivers, streams, and underwater volcanoes (Office of ocean Research 3). Because of the multiple sources of salt, the levels of salinity within the ocean shoot up rapidly. The Office of Naval Research states, Salinity is expressed by the amount of salt found in 1,000 grams of water (3). Marine ecologist created an expression for the amount of salt inside a given area. If there is one gram of salt within 1,000 grams of water, thus it is represented as 1 pound per ton (3). The oceans salinity varies between about 32 and 37 ppt (3). Most humans would not be able to conk out in an ecosystem with salinity levels being this high, however some organisms have adapt to surviving is such an environment. Osmosis is an animals way of adapting to different types of salinities (Office of Naval Research 3). All marine mammals have special traits that they adapted to facilitate them survive in or around marine habitats (Marietta College 1). As prompted by the Marietta College of Ohio Many organisms in saltwater are osmoconformers. (1). An osmoconformer is an organism that has the same minginess of salt within its body as the border water (1).... ...terials into the water and can threaten organisms (1). Most NSP is located close to peoples homes. Most importantly is the hazard material that is used and not in good order cleaned or disposed of. If people have a sep tic storage tank on their property, and it is not the correct size, they can leak and pollute surrounding ground water (1). Poisonous materials from cars and other vehicles such as oil, stop fluid, grease, and gasoline, can be washed off and channel into storm drains, bad them direct access to the ocean (1). If it is not being washed off, then another large problem is when it is spilled or dumped out (Hemminger 4). These products can be picked up by rain and pushed down into storm drains (Natural Resources Defense Council 1). The stand up most common NSP is when non-degradable products are flushed down the toilet, which can injure the sewage treatment process (1).
