1)you are a climatologist who has been given the task of finding out how much glaciers and ice caps have receded over the past 50 years.
2) you have at your disposal satellite image data from this entire time period.
3) How could you gather data (measurements) from the satellite images and what format would be a good way to present the data you have gathered?

  1. You could set up the years into months and locate the time on the x-axis, and plot the mass of the ice field on the y-axis. That way you could see that as the months progress the ice field gets smaller and smaller. The total mass in year one - the mass in the last of the 50 years will give you the amount that the mass has reduced : )
