Ah, yes, well
re. the Antarctic ship getting stuck, the sea ice there was "the result of a 2010 collision between an enormous berg known as B09B and the Mertz Glacier Tongue. As a result of this clash, B09B lodged itself on the seabed of Commonwealth Bay, changing the circulation of the area dramatically."

No mention of the record low temps recorded there in 2013 in that article, I see?
