Sea Ice conditions within the Antarctic Marginal Ice Zone in winter 2017, onboard the SA Agulhas II

Our knowledge of sea ice variability, which contributes to the detection of the Antarctic climate change trends, stems primarily from remotely sensed information. However, sea ice in the Southern Ocean is characterized by large variability that remains unresolved and limits our confidence on the remotely sensed products. Therefore, the in situ sea ice observations presented (according to the ASPeCt protocol) provide a greater understanding of the Antarctic sea ice environment - on a local scale - and allows us to evaluate remotely sensed products.

我们对海冰变率的认知可为南极气候变化趋势的检测提供支撑，而该认知主要来源于遥感观测数据。然而，南大洋海冰具有极强的变异性，这一现象迄今仍未得到充分解析，也制约了我们对遥感产品的置信度。因此，本数据集所呈现的、遵循ASPeCt协议的原位海冰观测数据，可帮助我们更深入地认知局地尺度的南极海冰环境，并为遥感产品的评估提供可靠依据。
