Sea Ice and Sunlight

In recent years, sea ice in the Arctic has been melting at an alarming rate. Scientists fear that Arctic shrinkage could contribute to rising sea levels worldwide. Oceanographer Victoria Hill (Old Dominion University) was one of five scientists who spent six weeks in the barren, frozen landscape, where temperatures fall to -40F. What she found in her core samples could provide clues as to why the ice is melting. Also featured: The energy crisis of the 1970s brought attention to solar technologies as an alternative to oil. Sylvain Marsillac (Old Dominion University), one of the nation’s experts on photovoltaic energy, says the U.S. should continue to fund solar energy research if we want to secure energy independence.

    I am curious to know if the investigation considered the affect of arctic oil spills such as the one in the Kolva River in 1994.

    At certain temperatures certain gases freeze and solidify. With the increase in particulate in our air, could this be where the exotic particulate is coming from? Possibly ice that has formed in the past three hundred years with increasing amount of ‘industrialized’ gases and particulate in our atmosphere?

    If the particulate is not present in the ice, could it be coming from the air? Were tests done to sample the environment other than the ice and water?

    Is there a micro-biologist on your team?

    I hope these questions make sense. I look forward to your reply!
