Ice core chemistry database: an Antarctic compilation of sodium and sulfate records spanning the past 2000 years
Changes in sea ice conditions and atmospheric circulation over the Southern Ocean play an important role in modulating Antarctic climate. However, observations of both sea ice and wind conditions are limited in Antarctica and the Southern Ocean, both temporally and spatially, prior to the satellite...
