 After the world's largest iceberg snapped off of the Antarctic Peninsula in July 2017, it drifted north on a three-year death march, shedding an unfathomable amount of meltwater into the sea. 

Now, a new study of the doomed iceberg (named A68a) reveals just how much water the infamous mega-berg actually lost — and how that could impact the local ecosystem for generations to come.
