Turbidity current

Water temperature increases as the turbidity increase. This is caused by the absorbance of heat by the suspended particles within the water body. This reduces the concentration of dissolved oxygen (DO) in the water since warm water holds less DO compared to cold water. Higher turbidity also reduces the amount of light that can penetrate the water, which reduces photosynthesis and the production of DO. Based on Wetzel and Likens (2000), turbidity in water is caused by suspended inorganic and…

Current issue in the Great Barrier Reef Great Barrier Reef (GBR) has been in the centre of topic for environmentalist for the past decades as it is the biggest and longest natural coral reef in the world. With thousands of exotic aquaculture species that are exclusive to that region only, it has become one of the heritage national marine parks in the world. However, with the mining boom in Queensland, more ports and industrial activities have been taken places along the coastal regions to boost…

disprove my hypothesis. I will be testing out four different antiseptics on E.coli bacteria while using turbidity and a spectrophotometer to measure bacterial growth. Small test tubes, called cuvettes, will be filled with non-pathogenic E.coli bacteria and a nutrient broth. In addition, a blank cuvette will be used to calibrate the spectrophotometer so that it will properly measure the turbidity of bacteria. Using the spectrophotometer, I will first use the blank cuvette in the spectrophotometer…

(4) The East Australian Current keeps the temperature in the region of the great barrier reef in this range as seen in the **picture**. This allows the coral in the Great Barrier Reef to thrive like none other. Corals are very sensitive to temperature and if the temperature increase…

Evaluating overall results compiled by practical investigations, the water sample showed very positive results with very minimal flaws in its purity. Observing the physical properties of the sample it had no turbidity and looked relevantly clear. Data shown here may be inaccurate due to many varied factors in the lab testing. Most of the testing heavily relied on the judgment of the human eye to compare charts colours possibly resulting in human error. A low 5 m/L’s was tested each time when…

Extensive human and mechanical activities accelerate the rate and amount of seashore erosion and results in higher turbidity of seawater. Impact of shipbreaking on inter-tidal sediments and soils: Various refuse and disposable materials are discharged and spilled from scrapped ships and often get mixed with the sand. The scraps from the ships are staked on the sea…

possible that both the sandstones and conglomerates have sediments transported from the same continental arc, but the arc was getting eroded down through. Its top volcanic rocks were first eroded and were carried to deposit in the submarine fans by turbidity currents as conglomerates, and the lower plutonic part was eroded to form the younger sandstones in the Moreno Formation. Sierran Arc is a plausible candidate for the continental arc that was eroded because of its spatial proximity to the…

Solubility Phosphates are not very water-soluble, thereby creating a limiting potential for plant-growth in marine ecosystems. This explains its encompassing effect on the surface of affected water system, as observed in the Watershed Nature Centre. In addition, this can be observed from the site as less quantity of phosphorus get dissolved in running water compared to the amount that eventually gets into the water column. Temperature: The water surface gets heated up by sunlight, increasing…

Introduction Water has become one of the most prominent natural resources gifted by the Mother Nature, since the early existence of all life forms on the planet Earth. With the vast improvements in society, the living beings, especially human’s consumption of water has advanced from solely for drinking, cleaning and cooking purposes to using water for entertainment and advanced infrastructure (mining) etc. Along with its consumption, there have been numerous issues arising about the ‘influence…
