How long did Deepwater Horizon leak?
87 days
Who cleaned up the Deepwater Horizon oil spill?
On 28 April, the US military joined the cleanup operation. The response increased in scale as the spill volume grew. Initially, BP employed remotely operated underwater vehicles (ROV’s), 700 workers, 4 airplanes, and 32 vessels.
When did the dead zone occur in Gulf of Mexico?
The Dead Zone was first recorded in the early 1970’s. It originally occurred every two to three years, but now occurs annually. In the summer of 1999 the Dead Zone reached its peak, encompassing 7,728 square miles.
What happens if we lose estuaries?
Other effects include a reduced amount of nutrients flowing from marshes, an alteration in tidal patterns, and the contamination of water, making the environment unsuitable for plant and animal life. The destruction of these estuaries caused a major loss to coastal environmental health.
What happens if estuaries are destroyed?
Estuaries are fragile ecosystems that are very susceptible to disturbances. If these beaches are destroyed, salt marshes and inland habitats adjacent to the estuary may become permanently damaged. Waves can also dislodge plants and animals, or bury them with sediments, while objects carried by the water can crush them.
What percentage of the ocean is oil?
Here are three little-reported sources of oil that contribute to oil pollution in North American oceans. Natural seeps of oil underneath the Earth’s surface account for 60 percent of the estimated total load in North American waters and 40 percent worldwide, according to the National Academy of Sciences.
Which ocean is the source of oil hub?
The most productive areas are currently the North Sea and the Gulf of Mexico, the Atlantic Ocean off Brazil and West Africa, the Arabian Gulf and the seas off South East Asia. For some years now the trend has been towards drilling in deeper and deeper water.
Does oil mix with water in the ocean?
The oil and the water appear to be mixing together. This is what happens in the ocean when oil and sea water get mixed up by the waves during strong waves or during a storm. At the same time, tiny amounts of water fill up the spaces between the oil blobs.
What is the mixture of oil and water called?
emulsion
How bad is oil for the ocean?
Because oil spills are localized, they can severely contaminate beaches and sediment, and cause serious harm to marine wildlife. Oil spills can suffocate fish, get caught in the feathers of birds and mammals and block light from photosynthetic plants in the water.
What can I use to mix oil and water?
The surfactant we will use is dish detergent, which helps break up the surface tension between oil and water because it is amphiphilic: partly polar and partly nonpolar. As a result, detergents can bind to both water and oil molecules.
Why does food coloring mix with water and not oil?
Vegetable oil is a non-polar molecule. Food coloring is a polar molecule so it WILL mix with the water. The water and the food coloring are both polar molecules and will mix together. That’s why the water blobs turn the color of the food coloring and the oil does not.
What happens when you mix water oil and detergent?
Detergent grabs onto both types of molecules causing oil droplets to be suspended in the water. When you shake the jar the detergent molecules adhere the water and oil together forming an emulsion. An emulsion is the combination of molecules that are not normally attracted to each other, that don’t usually mix.
