Antarctic Ice Core Data Supports Historical 'Seesaw' of Climate Instability (9 of 14)

Caption

The second Dome Fuji ice core from 3035 meters below the snow surface, freshly removed from the final drill run on Jan. 26, 2007. The drill team encountered difficulties because of basal melt at this site. The length of the core from each run was very short and the ice core is covered by a layer of refrozen basal melt. This material relates to a paper that appeared in the Feb. 8, 2017, issue of Science Advances, published by AAAS. The paper, by K. Kawamura at National Institute of Polar Research in Tokyo, Japan, and colleagues was titled, 'State dependence of climatic instability over the past 720,000 years from Antarctic ice cores and climate modeling.'
