Short summary
Icebergs account for about half of the freshwater lost from Antarctica. Because they can drift for long periods of time and across great distances, it is hard to know where in the oceans that water ends up, yet this is crucially important for ocean circulations and the global climate. We have developed a digital tool that can help us to understand the dynamics and effects of icebergs by recognizing them through time and doing “jigsaw puzzles” to reconstruct their family trees when they break apart.
