Antarctica contains no permanent human population; however the impact of climate change is being observed. Sea-ice is slowly becoming less thick and covering smaller areas of the Southern Ocean. Algae grow on the underside of this sea-ice which feed krill, which in turn support most of the Antarctic food web. Understanding how changes in sea-ice and snow thickness will change the productivity of Antarctica will have significant implications to our management of this wilderness. Knowledge of how sea-ice algae responds to changes in light can be incorporated in climate change models.

南极洲没有常住人口，但气候变化的影响正在观察之中。海冰正在慢慢变薄，覆盖南大洋的面积也在缩小。藻类生长在海冰的底部，它们喂养磷虾，而磷虾又支撑着南极大部分的食物网。了解海冰和积雪厚度的变化将如何改变南极洲的生产力，将对我们管理这片荒野产生重大影响。海冰藻类如何对光线变化作出反应的知识可以纳入气候变化模型。
