Coring at dome peaks increases precision of reconstructions as it is the place where horizontal motion is at its least.
They founded the WAIS project, which is funded by the United States National Science Foundation, and is run by scientists from many organizations e.g. National Ice Core Laboratory, Ice Drilling Design and Operations (IDDO), and over fifty universities.
The WAIS project is located in West Antarctica, and the goal is to look into the evolution of the Antarctic ice sheet and climate over the past 100,000 years.
This larger layer thickness means there is a smaller off-set between the ages of the ice and that of the air and gases trapped inside, allowing scientists to make more precise statements about how the atmosphere varied in the past.
The success of the WAIS project has educated scientists around the world as to how the atmosphere of Earth has changed dramatically over 100,000 years.
