Two major uncertainties in the behavior of Antarctic ice are reduced.
The Antarctic Peninsula, the northern and warmest region of Antarctica, is the largest frozen water reservoir on Earth. Around its coastlines, it is estimated that glaciers—massive blocks of moving ice—travel at an average speed of about one kilometer every year.
Additionally, glacier meltwater is estimated to have boosted global sea levels by 7.6 mm between 1992 and 2017.

Still, it has been difficult for researchers to acquire a more detailed insight into how this speed varies seasonally due to difficulties getting onto the glaciers to conduct fieldwork.
