Measuring Sea Ice Thickness with ICESat-2
This visualization depicts sea ice thickness in the Arctic Ocean as measured by ICESat-2 over the course of several months.
The visualization begins with a global view of the north pole as individual tracks are drawn over time representing each time the satellite passes overhead and collects sea ice data.
A closeup view of one track is revealed, showing how the ICESat-2 laser can measure ice freeboard (height above sea level), which can be used to calculate total ice thickness.
The visualization concludes by showing monthly average of sea ice thickness from November 2018 to March 2019.
