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.

On 2018-09-11 it was found, that the latitude and longitude were given in the wrong format here. Latitude and longitude are now corrected (now in the correct decimal degree, south and west are negative), and an erratum was added to this dataset (see Further details reference) explaining the change.
