Seawater

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…

Discovering a new world below the ocean intrigues me. I have never been one for loving ocean creatures, but I do enjoy learning about the world below us. I found several facts interesting as I read the articles including: how osmosis and salinity functions, how seawater cells move, how pH affects the ocean, how decomposition works in the environment, how upwelling stirs up nutrients, and how water temperature affects organisms. One of the interesting facts discusses why osmosis and salinity…

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…

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…

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).…

Aquarium can be designed in various types. One of the most attractive types is saltwater aquarium. It is a kind of aquarium that is designed with sea view. Besides that, the fish also belongs to sea fish. Of course, you should also apply saltwater. This aquarium should always be kept well so that the water and fish will always be healthy by removing the dissolved organic compound. To realize it, you need to skim it. There are many skimmers available in the market. If you are interested to look…

Saltwater angle aquariums come in various sizes to suit your necessities. The measure of your aquarium will decide what number of fish you can have as well as what assortments you can have since the difference in the extent of tropical fish shifts massively from an inch or two up to an astounding 18 inches. Dissimilar to freshwater angle aquariums, saltwater angle aquariums are more multifaceted to set up, require more upkeep and the aquarium itself in addition to the fish to go in it are more…

's a nice feeling to have betta fish for pet, and steps on how to care for betta fish is very much interesting topic to discuss. They truly can relieve work stress and even anxieties. Of course, who can resist from its flashy color, flaunting tails and alluring appeal? Betta fish is a tropical fish originally came from Asia. They come in different varieties and breed. Since they are freshwater fish, they are more likely to be placed in a small fish bowls or in a larger aquarium. They look…

Shark culling is a state government implemented policy in which sharks within the vicinity of a beach can be legally killed through shark nets or drumlines or a combination of the two. 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…
