Michelle Coomb, a geologist as stated that this is the sixth eruption since December 20th and that seismic data has resulted in data that stated that there has been several eruption in the past month. This volcano last erupted in 1992, there was no instruments there since it was protected under the Alaska Maritime National Wildlife Refuge. With this restriction scientist have relied on observations with equipment in other locations and satellite imagery. Also, they use data from the World Wildlife Location Network, which has equipment in 40 different locations that detect lightning flashes. With the increased ash clouds surround the volcano, researchers are able to use this network to see when the volcano is erupting. With the images from satellites, scientists can see when the volcanic vents that are found underwater are producing more material which results in changes of the island itself. Dr. Coombs stated that if this continues it could build a cone above sea level. As the change of a large eruption could meet landfall in Unalaska and its port which has roughly a population of 4,000. Although this is rare the ashes fall could be hazardous the population there. The biggest concern of the ash affecting the airplane and that the air travel in that area could be closed. There has been in travel restricts has of yet. 

This area is sitting on the Pacific Ocean plate that is subducting under  the North American plate which is where many volcanoes are studied.  

This regulations relies on the 1953 law that states the president had the power to stop oil and gas drilling forever in some of the waters that are US federally controlled. this action may be impossible but the law did not include the provision for a  future president to undo the action done by past presidents alsos no president has ever tried to change it. With energy being a main centres the re may be a chance for the law to be changed in the courts or in the Congres. 

This decision is a change for Obama which has had the domestic oil production rise in his presidency and who supported the fossil fuels drilling  the arctic to be part of  comprehensive energy plan.ut in the past year he has changed his view.s He has gotten praise from the environmental groups. The energy industry is now to to drilled in these arctic areas which cost a lot of money for these companies that need to explore these areas. There has been criticism by republicans who stated that oil could help the economy and create jobs with this plan stated “Arctic development is one of the best ways to create jobs, generate revenues and refill the Trans-Alaska Pipeline,” said Alaska GOP senator Sen. Lisa Murkowski in response to Obama’s five-year ban last month. “Why the president is willing to send all of those benefits overseas is beyond explanation.”

In this experiment the researchers looked at birth record in New York city from 1994 to 2004, while isolating the Lower Manhattan area. They also made to their search for women that have ad given birth before which would rule u some anomalies. In the research found moher in the third trimester during the terrorist attack had higher chance of premature birth, Also an increase of newborns with low birth rates that would then lead to risk of diabetes, elevated blood pressure and heart disease. PTSD was ruled out as a factor by comparing the levels of stress across the city. They stated the main reason of these birth defects was the dust cloud which result in air pollution. 

This study has further repression for cities that have high air pollutants. With ot of the research n air balloons taking place over long periods of time, the terrorist attack occurred in a set place and time this gives researchers the chance to understand the consequences of this air pollutions. This was the cose thing to a controlled environment to conduct the research. As one researcher stated “That’s the whole reason why this kind of disaster research is useful in a sense, not because this is something that is very representative in general, but because it allows you to identify the effects of pollution,” says Schwandt. “It’s like switch on, switch off.”

While climate change will decrease the amount of sea ice in the arctic the better chance that the kelp will be able to survive and flourish which would hopefully increase these refuge areas in the sea where species are able to take refuge from the increasing acidic quality of the oceans surrounding these kelp filled areas. Studies have been conducted to further research the properties of kelp in seawater, one found that even in different coastal conditions with different light levels and baseline pH levels found that fluctuations in pH levels happened and concluded that the kelp makes its own trends in seawater. As the study of ocean acidification is newer in research for now focusing on open ocean impacts of the increasing acidity. While the coastal areas are even more complex compared to the open ocean. The fluctuations of the coastal areas pH is in constant changes due to the night and day time.
