The oil sits on the surface of the water, which leads to sunlight not reaching the plants and animals beneath the surface that rely on that sunlight to live. No sunlight for the plants mean the plants die, which means there is less available oxygen in the water for the fish and other creatures]]> 2017-04-05 03:10:24 UTC https://padlet.com/echaztrey5/ngdtzr3ijk0j/wish/164775188 wcounts21 https://padlet.com/echaztrey5/ngdtzr3ijk0j/wish/164775323 With no sunlight reaching the plants and plants dying, the organisms that find shelter and/or eat the plants are left to die]]> 2017-04-05 03:13:08 UTC https://padlet.com/echaztrey5/ngdtzr3ijk0j/wish/164775323 wcounts21 https://padlet.com/echaztrey5/ngdtzr3ijk0j/wish/164775738 Oil is very slick and heavy, and it can get stuck to the fur of mammals, leading to suffocation or death.

These currents are streams of seawater that circulate through the ocean. Once oil is introduced to the "streams" they are quickly spread through different ecosystems (water levels). ]]> 2017-04-05 13:10:19 UTC https://padlet.com/echaztrey5/ngdtzr3ijk0j/wish/164862801 1371523 https://padlet.com/echaztrey5/ngdtzr3ijk0j/wish/164864595 Depending on the time of year, models are constructed to represent the best estimate of how ocean currents are likely to respond under wind and weather conditions. ]]> 2017-04-05 13:15:45 UTC https://padlet.com/echaztrey5/ngdtzr3ijk0j/wish/164864595 1371523 https://padlet.com/echaztrey5/ngdtzr3ijk0j/wish/164865721 A liquid release on the surface, is likely to slowly spreads it mixes into the ocean currents and is introduced to the "loop current"which circulates throughout large portions of the ocean. ]]> 2017-04-05 13:19:05 UTC https://padlet.com/echaztrey5/ngdtzr3ijk0j/wish/164865721 1371523 https://padlet.com/echaztrey5/ngdtzr3ijk0j/wish/164866838 Upwelling results in the blockage of nutrients to reach the surface. ]]> 2017-04-05 13:21:57 UTC https://padlet.com/echaztrey5/ngdtzr3ijk0j/wish/164866838 1371523 https://padlet.com/echaztrey5/ngdtzr3ijk0j/wish/164869705 2017-04-05 13:29:44 UTC https://padlet.com/echaztrey5/ngdtzr3ijk0j/wish/164869705 1371523 https://padlet.com/echaztrey5/ngdtzr3ijk0j/wish/164870373 2017-04-05 13:31:51 UTC https://padlet.com/echaztrey5/ngdtzr3ijk0j/wish/164870373 1371523 https://padlet.com/echaztrey5/ngdtzr3ijk0j/wish/164872093 March 24, 1989 and oil tanker owned by Exxon Shipping Company struck Prince William Sound's Bligh Reef and spilled 10.8 billion of crude oil.

No supervision for the master and crew on the ship. This prompted a safety recommendation for the entire oil industry. Served as a "wake up call" to the industry.
Clean up- a chemical dispersant was applied to the oil, 15,000 to 30,000 US gallons of oil were collected using floating boom towed behind two fishing vessels, and ignited. ]]> 2017-04-05 13:40:28 UTC https://padlet.com/echaztrey5/ngdtzr3ijk0j/wish/164873494 echaztrey5 https://padlet.com/echaztrey5/ngdtzr3ijk0j/wish/164878892 Most of these oil spills happen near the shore but the coastlines are affected disproportionately. As the oil begins to disperse, this will lead to more negative effects to the continental shelf. The oil also negatively affects the sediment on the shorelines ]]> 2017-04-05 13:56:27 UTC https://padlet.com/echaztrey5/ngdtzr3ijk0j/wish/164878892 echaztrey5 https://padlet.com/echaztrey5/ngdtzr3ijk0j/wish/164879262 For a solution to clean up oil spills I will incorporate a three step process. First we will use the ocean to our benefit and use bacteria in the ocean to "eat" the oil. To increase the bacteria in the ocean we will introduce sulfates and nitrates to multiply the microorganisms by 5 times. Next use a system of magnets, developed by students from Yale to extract oil. And finally to eliminate the remaining oil we'll develop a machine that will take in the contaminated water and like a filter with extract the oil, depositing the rest of the water back into the ocean.]]> 2017-04-05 13:57:22 UTC https://padlet.com/echaztrey5/ngdtzr3ijk0j/wish/164879262 echaztrey5 https://padlet.com/echaztrey5/ngdtzr3ijk0j/wish/164894482 2017-04-05 14:39:10 UTC https://padlet.com/echaztrey5/ngdtzr3ijk0j/wish/164894482 echaztrey5 https://padlet.com/echaztrey5/ngdtzr3ijk0j/wish/164896301 2017-04-05 14:43:47 UTC https://padlet.com/echaztrey5/ngdtzr3ijk0j/wish/164896301
