DangerousCatch-Group5

Dangerous Catch (Pd 3) “Our massive demands on the ocean’s bounty impacts life far beyond the shoreline: bushmeat hunting is on the rise in Ghana while in Namibia; fishing grounds struggle to recover as putrid fumes explode from the ocean depths and poison the waters; and radical new fish farms are sprouting up from Puerto Rico to Canada. Across the globe, all life is feeling the effects of overfishing. Can we protect fish in time to safeguard the ocean, life on land and ultimately ourselves? Find out how we all can make a difference.”

Group 5: Gulf Oil Spill

· [|http://www.sciencenews.org/view/generic/id/63094/title/FOR_KIDS_Gulf_oil_finds_many_] · How much oil was spilled in the Gulf between April 20 and July 15, 2010? · Where has the oil that has not been cleaned from the surface gone according to Woods Hole Oceanographic Institution? How much did they find? · Explain the term “plume.” · What is a “natural” tool that is helping cleaning the oil under the surface?

Summary: On April 20, there was a huge oil spill into the Gulf of Mexico that spilled 4.9 million barrels of oil. Much of the oil has risen to the surface, but other large plumes have sunken beneath the surface. Only 10% of the oil has been removed from the water, and another 10% has evaporated into the atmosphere. There has been 4 plumes discovered about 3,000 feet below the surface. Some of the oil is underwater and now we can't see it. Plumes are like a gaint cloud underwater. In fact they can be as tall as a 50 story office building and more than a mile long. Usually oil is less dense so it will float on water, so why is so much oil under water? Roberto Camassa has the anwser. If the oil particles are small enough, density doesn't matter, the oil particles will travel with the water. So, scientists see improvement. Some of the cleanup has been left in the hands of microbes that improve the chance of cleanup under the surface of the water. There is still a ton of effort being put into cleaning up the gulf, and research to better understanding in this massive problem.

**Question #1)** Between April 20 and July 15, 2010, 4.9 million barrels of oil spilled from the Gulf of Mexico. This is more than enough water to fill 300 olympic size swimming pools!

**Question #2)** The oil that has not been cleaned up from the surface has gone about 3,000 feet beneath the water surface. The cloud of oil is more than a mile long and was about as tall as a fifty story office building. According to researchers, this is mysterious because oil normally floats on top of water because it's less dense.

**Quetion #3)** Plume is a space in water, soil, or air in which it contains pollutants that are released from a specific point source, like a cloud beneath the water surface, developed by the oil spill.

**Quetion #4)** Microbes, which are minute life forms, are a natural tool that has helped clean the oil underneath the water surface.  <span style="display: block; font-family: 'Trebuchet MS',Helvetica,sans-serif;"><span style="color: #ff0000; font-family: 'Trebuchet MS',Helvetica,sans-serif;">Good Summary. 75/75
