In recent years, climate scientists have been concerned about a so - called «methane time bomb» on land, which would be detonated when warming Arctic temperatures melt permafrost and cause frozen vegetation in peat bogs and other areas to decay, releasing methane and carbon dioxide.

Another goal is to learn more about how greenhouse gases interact with the climate, so scientists want an accurate record of how carbon dioxide levels have fluctuated over time.
