Acidification in our Oceans Oceanography April 2‚ 2013 What is Ocean Acidification? “Ocean Acidification‚ is the worldwide reduction in the pH of seawater as a consequence of the absorption of large amounts of carbon dioxide (CO2) by the oceans.” (Britannica). Ocean acidification is largely the result of loading Earth’s atmosphere with large quantities of CO2‚ produced by vehicles and industrial and agricultural processes. Since the beginning of the Industrial Revolution about

Sea Stars (no longer considered called Star Fishes) are marine animals‚ part of the class Asteroidea. They are carnivorous invertebrates and can live up to 35 years. Despite the number of arms on a sea star averaging 5‚ they can grow up to 40 limbs. Sea Stars can be found almost anywhere but those located in the Pacific Ocean are getting hit with a mysterious condition. This condition starts out as a white or black lesion on the sea star’s body. From there‚ it spreads all over the body‚ causing

Technology we may see in the next 50 years... Technology | Positive effect of individual and society | Negative effect of individual and society | Self-driving cars | The positive effect of self-driving cars on an individual would be that the driver is less stressed and tired by driving and an individual could multi-task whilst the car drives. The impact of society would be fewer accidents as the system would control itself therefore drivers would not cause accidents on the roads. | The negative

Part 1: 1. Describe four factors that influence ocean currents. There are many factors that influence ocean currents‚ four of the factors would be planet rotation‚ wind‚ density of water‚ and gravitation. Planet rotation causes the currents to move clockwise in the northern hemisphere and counter clockwise in the southern hemisphere. Wind blows on the surface of the ocean therefore pushing the water in the direction of the wind. Different densities in the water can cause currents to form and move

Where Do We Go Next Over the course of history‚ humanity has taken strides that have propelled us to be the most intelligent species that we have discovered. From the beginning of cavemen who could no more than grunt a command‚ to wireless communication and computer controlled systems‚ human innovation and gain have taken unbelievable strides. In one hundred years‚ we have gone from dreaming of flying through the air‚ to walking on the moon‚ and now taking pictures of distant galaxies from far

sound in the air and it’s nothing like I’ve ever heard before. Jet carriers are the source of the strange sound as they zoom at impossible speeds above us. The carriers are a streak of black on the city and what I can make out; they’re nothing like the carriers I’m used to. Normal carriers begin to land on the roofs tops in the distance and that’s why there’s an echoing of marching boots. Order troops are being unloaded from those carriers or I guess. I can’t see

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
