China has embarked on its first airborne survey of marine glaciers in the southwest region of Xizang. On Tuesday, a research team began investigating the Renlongba Glacier in Qamdo City, aiming to study the development patterns and melting changes of these majestic ice formations.
Marine glaciers, found in polar or high mountain regions, are natural ice bodies that have existed for years and can move along the ground. They are known for their higher ice temperatures and rapid melting and freezing cycles. Wang Shanshan, a senior engineer from the Natural Resources Airborne Geophysical and Remote Sensing Center of China (AGRS), noted, “Marine glaciers have distinct movement patterns that are quite evident due to their unique characteristics.”
The survey team is operating at elevations above 4,700 meters, facing challenges such as high altitudes, low temperatures, and vast areas. This comprehensive survey integrates satellite, aerial, and ground-based methods to overcome the difficulties presented by variable climates and complex terrains.
“This mission is a national geological survey,” said Xiong Shengqing, chief scientist from AGRS. “By utilizing a multi-dimensional observation and monitoring system, we aim to map the distribution, thickness, and changes of marine glaciers to calculate the amount of ice reserves.”
Marine glaciers are not only a precious source of solid freshwater but also a highly sensitive indicator of global climate change. Understanding their behaviors is crucial for comprehending global water cycles and climate regulation. “The melting of glaciers may lead to changes in biodiversity, climate, and even sea levels,” Xiong explained. “By conducting on-site surveys, we can obtain more accurate data to analyze and predict their impacts on water resources, the environment, and ecosystems.”
