GISP2 (Greenland Ice Sheet Project 2)

GISP2, or Greenland Ice Sheet Project 2, was a significant scientific project conducted in the 1990s to study the Greenland Ice Sheet. Researchers drilled deep into the ice to collect ice cores, which are cylindrical sections of the ice that contain layers of ice and trapped air bubbles. By analyzing these cores, scientists could learn about past climate conditions, greenhouse gas levels, and how the ice sheet has changed over time. The findings from GISP2 have greatly improved our understanding of climate change and the ice sheet's role in global sea level rise.
