Multi-year spatial distribution of Antarctic sea ice (1988 - 2017)
In this study, we used daily sea-ice concentration data from the National Snow and Ice Data Center from 1988 to 2017 to investigate the spatial distribution of Antarctic sea ice by calculating the annual mean sea-ice concentration and multi-year sea ice in five sub-regions of Antarctica.
