Just because a scientist puts a GPS tracking collar on a wild polar bear does not mean the animal will willingly keep it on. They can remove it, if one becomes annoying. But scientists have now found a way of using signals from those dropped collars to track the ice itself.
The scientists identified 20 collars that transmitted movement data consistent with ice drift (漂流) rather than polar bear motion between 2005 and 2015. The resulting records of how melting ice drifts in Hudson Bay are unique; there are no easily accessible on-the-ground sensors, and satellite observations often cannot accurately capture the motion of small ice sheets.
The team compared the removed collars' movements to widely used ice- drift modeling data from the U.S. National Snow and Ice Data Center(NSIDC). Collar data indicated that the NSIDC model underestimates the speed at which ice moves around in Hudson Bay- as well as the overall extent of drift. Over the course of several months the model could diverge (偏离) from an ice sheet's location by a few hundred kilometers, the scientists say.
This means the bears may be working harder, when moving against the direction of the ice, than scientists had assumed, “Since we' re underestimating the speed of drift, were likely underestimating the energetic effort of polar bears," says Ron Togunov, who led the study.
The study reveals timely insight into how highly mobile ice moves. As melting increases in coming years, such ice will likely become more common farther north, in the central Arctic, says Andy Mahoney, a geophysicist at the University of Alaska, who was not involved in the study. Scientists had known NSIDC data could underestimate drift speeds, Mahoney says, but “any time we can find a data gap and plug it is a good thing.”
Plus, such data could improve predictions about how oil spills or other pollutants may spread in seas littered with drifting ice, says Walt Meier, a senior NSIDC research scientist. The findings may even influence future NSIDC models, “It’s a really nice data set," Meier says. “And certainly one we'll take under consideration.”
