Researchers have tracked millions of ice floes over decades to understand why some sea ice melts while others survive.
The tracking combined satellite data, weather reports, and buoy data into a database covering nearly 20 years of information.
The study found that an ice floe's fate depended on the route it took, with ice slipping into warmer, more southern regions more likely to melt.
Region-specific effects were also observed, such as thick sea ice in the East Siberian Sea being more likely to melt in the summer possibly due to warmer currents.
