Study Sheds More Light on Overall Sea Ice Changes in Southern Hemisphere
Written by AZoCleantechMay 6 2021
According to a new study, headed by the University of Maine, sea ice cover formed in the Southern Hemisphere is highly variable, from winter to summer periods and from one millennium to the next. On the whole, sea ice has been rising for around 10,000 years but with certain exceptions to this pattern.

Dominic Winski, a research assistant professor from the Climate Change Institute at the University of Maine, led a study that investigated the chemistry of a 54,000-year-old South Pole ice core and subsequently revealed new data about the variability of sea ice over the centuries, specifically across seasons, in the Southern Hemisphere.

Sea ice cover in the Southern Hemisphere is extremely variable, from summer to winter and from millennium to millennium, according to a University of Maine-led study. Overall, sea ice has been on the rise for about 10,000 years, but with some exceptions to this trend.
Dominic Winski, a research assistant professor at the UMaine Climate Change Institute, spearheaded a project that uncovered new information about millennia of sea ice variability, particularly across seasons, in the Southern Hemisphere by examining the chemistry of a 54,000-year-old South Pole ice core.
The Southern Ocean experiences the largest seasonal difference in sea ice cover in the world, with Antarctica surrounded by 18.5 million-square-kilometers of sea ice in the winter and only 3.1 million-square-kilometers of it in the summer. According to researchers, this seasonal disparity in sea ice has a significant influence on regional and global climate, yet scientists for years knew relatively little ab
