Greenland Ice Sheet MeltingHannah BourneEPS 109Fall
2013MethodsSimulated melting of Greenland Ice Sheet and predicted
sea level riseFound the coordinates of Greenland and used data from
topography_180x360_grid.txtCreated a new Greenland.txt file that
has a size of 28 by 51Made two additional matrices:Greenland_Ice
(height of ice block)Greenland_Temp (temperature of each
pixel)Simplified initial conditions:Set a constant temperature of 5
degrees Celsius for the air over the ocean and -2 degrees for the
ice in the ice blockCovered Greenland (i.e. all land) in a constant
thickness of ice (40 units)Used the heat diffusion equationIf the
corresponding Greenland_Temp of a Greenland_Ice pixel became
>=0, I decreased the altitude of that ice pixel by 0.1 unitsRan
as a while loop while max(max(Greenland_Ice))>=0If all of
Greenland Ice were to melt it is predicted that sea level would
rise 7.9 meters. I then calculated how much sea level rose using a
modified ocean area code from lab, but due to bad resolution, can
only see a .4% increase in ocean areaTo run my code, the
Greenland.txt file needs to be added to the path, because it is
read in, then run the code Final_Ice_2.mHannah BourneGreenland Ice
