    An estuary is a body of water in which fresh water from streams and rivers flows into seawater-containing oceans (Estuaries, 2008). The mixture of both seawater and fresh water is termed brackish water (Estuaries, 2008). Salinity depends on the exact location of an estuary, as the salt concentration is nonexistent in the fresh water end compared to the sea water end. The normal levels of salinity are between 0.5 to 35 ppt (Estuaries, 2008). Based on the central location of the fish kill site, the salinity level should be between 0.5 to 35 ppt. The typical pH range for an estuarine system is between 5 and 9, which is the range most finfish populations adapt to live in (pH, 2012). The main chemical species responsible for affecting the pH include the levels of oxygen and carbon dioxide (pH, 2012).…

    Desalination is the process where salt is removed from seawater or brackish water. People have been trying to remove salt from seawater since around 300 BC. People such as “Aristotle in 1320 BC, Rome’s Pliny the Elder in 70 AD, Greece’s Alexander of Aphrodisias in 200 AD, French Explorer Jean De Lery in Brazil in 1565, and James Cook during his circumnavigation around the world have tried to desalinate seawater .” (Desalination Overview – November 2013) Humans and animals cannot drink salt…

    its process that keeps pH balanced it's fast enough. We keep putting more CO2 in the air and the ocean is taking it all in. Since the pH levels are not balanced the marine life is dieing and cannot be stable in the water because of the acid. The shells from these marine life are already dissolving in the more acidic seawater. We don't know what going to happen to the marine life some of them might be able to survive and others will go extinct. Fishermen might lose their jobs since all the fish…

    currents in the world. The warmer waters found on the east coast create an environment for many different types of marine life, therefore, resulting in a high amount of biodiversity in this region. The coast of South Africa is one of the most biologically diverse marine environments on the planet, containing approximately 11,000 different types of species of marine animals, numerous different marine plant species and roughly 83% of all the marine fish families known to man (van der Elst, 2007).…

    Near bottom waters would have higher TAN concentration because of decaying organic matter on the bottom. These waters would also generally tend to have lower oxygen concentrations and higher salinities. When natural upwelling events happen, these colder, high TAN and low oxygen waters would be brought up to the surface. Majority of this TAN would also be in the form of toxic unionized ammonia NH3 as pH of the water would be higher in saltwater environment. So, care must be taken not to draw…

Drumlines are unmanned buoyant drums anchored one kilometre of a beach's shoreline. In between the drums are ropes with hooks. Drumlines are baited so that if a shark is swimming in the vicinity of a beach it would be attracted to the bait and not humans. Each state has different policies on drumlines depending on…
