There is a huge screen that must be more than 25 feet high on the wall in one of the entrance areas at MoMA. It is a screen that shows a very slow movie scrolling upward, made up of 88 digital images of ice cores drilled through the Greenland ice sheet between 1989 and 1993. The drilling of the cores descends two miles and 110,000 years in time. Each year there is an annual "layer" of ice that is formed and these layers preserve time vertically, by trapping bubbles of atmospheric gases, giving a record of what was in the air at the time. I chose to do a close up cropped version of the photograph first because it is mysterious photograph - you are not sure of what you are looking at.
This is the full frame image of the core movie, slowly scrolling upwards. To watch the entire movie of 88 cores takes something more than 4 hours! But it was fascinating to look for changes in the appearance of the ice as the movie slowly scrolled up.
