Starfish Crayfish coral Some Bottom dwellers clean the ocean floors Bottom dwellers refers to any species of animal or some other organism that lives on the sea floor. Biologists often use the term benthos to refer to bottom dwellers. Benthos feed off algae. Examples include many species such as crab rock-fish worms sea slugs sea snails.

Oceans are polluted to a great degree due to humans using plastic and not being recycled. The article “Trashing the Oceans‚” by Thomas Hayden‚ which was published in U.S. News and World Report‚ states how the oceans are being polluted by the trash going within it. Another article “Managing Marine Plastic Pollution‚”John H. Tibbetts‚ was published in Environmental Health Perspectives‚ demonstrates how the pollution is greatly impacting the ocean. The article “Trashing oceans” utilizes ethos‚ logos

Ocean acidification is the ongoing decrease in the pH of the Earth’s oceans‚ caused by carbon dioxide from the atmosphere‚ Seawater is slightly basic (meaning pH > 7)‚ and the process is a shift towards pH-neutral conditions rather than a transition to acidic conditions (pH < 7). Ocean alkalinity is not changed by the process‚ or may increase over long time periods due to carbonate dissolution. An estimated 30–40% of the carbon dioxide from human activity released into the atmosphere dissolves into

The ocean as vast and as mysterious as it is‚ is facing problems caused by humans dumping waste into it and that is causing marine life to be harmed. It was thought that the ocean was so deep and huge that no matter how much garbage you put into it would have small consequences. As we have seen that is very wrong‚ here are a few of the problems ocean pollution cause: Toxic metals can destroy the biochemistry‚ behavior‚ and reproduction of marine life. Fertilizer runoff creates eutrophication that

Ocean acidification is caused by CO2 in the atmosphere when it reacts with water it creates carbonic acid. It’s a significant and harmful consequence of excess carbon dioxide in the atmosphere that we don’t see or feel because its effects are happening underwater. When carbon dioxide is absorbed by seawater a chemical reaction occurs that reduces the seawaters pH‚ carbonate ion concentration‚ and saturation states of biologically significant calcium carbonate minerals. It decreases the pH of seawater

Vaughn‚ par 9). For generations the ocean has been called “The largest museum on earth” (Vaughn‚ par 8). The Earth has been maintained in a natural state of balance‚ but the advancement of human civilization has thrown it off balance (Stewart‚ video). Each year as humans evolve we destroy the Earth along with its natural resources (Rekacewicz‚ par1). Almost everything depends on water and it’s cycle. However‚ the oceans

Summary and Response to Ocean Acidification Article The National Geographic article “Ocean Acidification; Carbon Dioxide is Putting Shelled Animals at Risk‚” argues that the drop in surface pH could have a devastating effect on not only the organisms living in the ocean‚ but the environment that surrounds us. Research has shown that at least half of the carbon dioxide being emitted into the atmosphere has been absorbed by the oceans over time. This has benefited our environment because by

CHAPTER 31 OCEAN CURRENTS TYPES AND CAUSES OF CURRENTS 3100. Definitions The movement of ocean water is one of the two principal sources of discrepancy between dead reckoned and actual positions of vessels. Water in motion is called a current; the direction toward which it moves is called set‚ and its speed is called drift. Modern shipping speeds have lessened the impact of currents on a typical voyage‚ and since electronic navigation allows continuous adjustment of course‚ there is less need to

What is the composition of seawater? The salinity of seawater ranges from 3.3 to 3.7%. When seawater evaporates it leaves behind sodium chloride‚ better known as table salt. The other components of seawater are acquired through various methods. One of which is weathering. Chemical weathering of rock releases
