light penetrated the water and turbidity is the measure of the light scattering property of water. In this experiment‚ Secchi disk was used to directly measure the amount of penetrated sunlight and indirect amount of the suspended materials in the seawater. The study site was at the littoral zone of the ocean. The coordinates recorded for the study site were found to be N 160 23’ 56.0” E 1190 54’ 06.5” and N 160 24’ 02.5” E 1190 53’ 59.5”.

A Healing place－Miyako Island‚ Okinawa‚ Japan Miyako Island is the best place to spend a vacation for three reasons. Before starting my recommendation‚ how much do you know about the island? It is located in the Pacific Ocean and about 300 km southwest from Okinawa Main Island. The land is flat‚ shaped just like a right-angled triangle and much of the arable land is used as sugarcane fields. And also‚ the island is a very popular vacation place among Japanese people because of its mild

Ocean Acidification and its Effects on Marine Butterflies and Coral Reefs For millions of years‚ Earth’s oceans have maintained a relatively stable acidity level. Research shows that a recent and rapid drop in surface pH that could have devastating global consequences through the unbalance the ocean’s acidity. Since the beginning of the industrial revolution in the early 1800s‚ fossil fuel-powered machines have created a burst of industry and machines. The consequence of this industrial revolution

Lab #5: Dissolved Oxygen Lab Be sure to read and understand the below instructions BEFORE the lab! Experiment 1: Investigating the Effect of Temperature and Salinity on the Concentration of Dissolved Oxygen in Water Introduction: In an aquatic environment‚ oxygen must be in a solution in a free state (O2) before it is available for use by organisms (bio-available). Its concentration and distribution in the aquatic environment are directly dependent on chemical and physical factors and are

when body fluids whose concentration is different from that of their environment‚ so these organisms use up a lot of energy in having to control and gain water. An osmoconformer‚ is when body fluids with a solute concentration is equal to that of seawater. Furthermore‚ this report aims to identify the osmoregulator and the osmoconformer of the given species as well as to compare the specific gravity of each body fluid. Materials: As per the BI108 lab 6 handout. Method: As per the BI108 lab 6

Managing Water Supply Freshwater * Only 3% of the Earth’s water is fresh water‚ 97% is sea water. * Only 1% of the total amount of water is available for human use. Water as a scarce resource Reasons for scarcity: - Due to increasing demand as annual global use of water has increased 7 fold. -Uneven distribution of precipitation -Climate change leads to disturbances to water cycle - Deforestation leads to higher surface runoff which causes less clean water. - Poor or improper farming practices

Magnesium Oxide: Origin‚ Production and Utilization Magnesium oxide is a basic or alkaline kind of earth metal that naturally originates from seawater. The compound is odorless and colorless that makes it difficult to see by the naked eye. To produce such compound‚ extraction from the seawater by electrolysis and several chemical processes id done. The compound is formed from the thermal processes which make uses of air and oxygen. Magnesium hydroxide is also produced. The versatility of uses of

when man-made products like gasoline‚ oil‚ road salts‚ and chemicals get into the groundwater and cause it to become dangerous for us to use. The state of California can prevent groundwater depletion by harvesting stormwater‚ reusing water‚ and seawater desalination. Instead of taking groundwater David Sedlak claims that we should harvest stormwater. Even though it is not a very reliable source since it hardly ever rains in California we can slowly collect the water to refill our aquifers back
