Japanese researchers have developed a new method to estimate the thickness of the Arctic pack ice, based on satellite data.
The Arctic pack continues to decline. Scientists say that to more accurately assess its volume, it is essential to know not only its extent, but also its thickness. However, the methods of measuring the thickness of the pack ice have limitations.
A team of researchers analyzed satellite observation data to determine when and where the Arctic ice was formed and how it evolved over time.
The researchers then combined their tracking data and weather conditions, including temperature and humidity, to estimate the thickness of the ice. They say their estimates are in line with the direct observations.
The group says it hopes that this new method will contribute to a more accurate estimate of the volume of the Arctic sea pack.
Kimura Noriaki, an associate professor at Kochi University, said it was necessary to understand both the extent and thickness of the pack ice to know what is happening in the Arctic.
Mr. Kimura said he hoped that this new method will detect the first signs of a decrease in ice and improve the accuracy of global warming studies.
