Story summary

Researchers in Greenland use fiber optic cables to study glacier calving, impacting sea levels.
Distributed acoustic sensing (DAS) detects vibrations from ice breaking off glaciers.
Recent findings indicate models underestimate ice melting at the sea-glacier interface.
DAS data reveals calving stirs warmer water, accelerating glacier melting.
Future efforts will focus on long-term monitoring and early-warning systems for ice-induced tsunamis.
