artic tundra oil and gas Flashcards
why did the development of oil and gas industries on northern slope face challenges
low investment and the cost was seen as too high
what infrastructure was built on the northern slope
trans Alaska pipeline
built between 1974 - 1977
how much oil does the pipeline carry a day
700,000 barrels of oil a day
how has % of oil production changed between 1980 - 2014
1980 - 1524 thousand barrels a day
2014 - 479 thousand barrels a day
how do ice roads impact the carbon cycle
removal of vegetation to make the ice roads - cause permafrost to melt - releasing CO2
infrastructure diffuses heat directly to the atmosphere
how does does from human activity impact the carbon cycle
causes the snow to darken - snow absorbs more sunlight - increased concentration of sunlight - increased snow melting - more co2 released - lowers temp of ground
how does the removal of vegetation impact the carbon cycle
permafrost is no longer insulated - more exposed - due to rising global temp - permafrost will melt - decrease store of carbon - carbon source
what have been the management strategies on the north slope
roads built on insulating ice and gravel pads to prevent melting permafrost
buildings and pipelines elevates on piles to allows cold air to circulate beneath
