Nearly half of the freshwater flux from the Antarctic Ice Sheet into the Southern Ocean occurs
in the form of large tabular icebergs that calve off the continent's ice shelves. However,
because of difficulties in adequately simulating their breakup, large Antarctic icebergs to
date have either not been represented in models or represented but with no breakup
scheme such that they consistently survive too long and travel too far compared with
observations. Here, we introduce a representation of iceberg fracturing using a breakup …
