IIR, "capture" is the geological term used when one river or stream starts taking water from another. (Generally due to erosion shifting their courses.)
No idea if there is a correct geological term for what's happening here - but "theft", "steal", and "piracy" get the clicks, so...
the title could just be an example of how a person ends up thinking after bieng on station in antartica......glaciation starts to become personal
This is another case of the theft of the word theft for something that wasn't a theft.
The term "theft" and "steal" feels really odd to me when referring to ice or glaciers, or anything that is inanimate (?).
For example this sentence: "Usually, when glaciers come into contact they merge and continue flowing together. They have also been recorded stealing ice from one another" just left me more confused than before. What does it mean for glaciers to "steal ice" from one another? I understand "merge" but not "steal" in this context.
