As The Climate Shifts A Border Moves
Not all natural boundaries are as stable as they might appear. Italy, Austria, and Switzerland’s shared borders depend on the limits of the glaciers and they have been melting at increased rates due to climate change. This has caused the border to shift noticeably in recent years. The border lies primarily at high altitudes, among tall mountain peaks where it crosses white snowfields and icy blue glaciers.

Peruvian Study Opens Doors for Glacial Research
A study published in March of this year by researchers from the University of Quebec presents a new avenue for glacier retreat research. While most water-related glacier studies are concerned with water availability, the research presented in this article is distinctive in that it draws a link between glacier retreat and water quality. This work has important implications for populations in the study area and others living in glacierized regions around the world.

Acoustics of Meltwater Drainage in Greenland Glacial Soundscapes
Remember the age-old adage, “If a tree falls in the forest and no one is around, does it make a sound?” For centuries philosophers have tested our minds with such questions, and certainly the answer depends on how the individual chooses to define the word sound. Scientists would say that if by sound, we mean the physical phenomenon of wave disturbance caused by the crash, we would undoubtedly concur. Indeed, in recognizing the uniqueness of audio frequencies, the scientific practice of studying environmental soundscapes has proven effective at providing information across a varied range of phenomena. But glaciers represent a relatively new soundscape frontier.
“Glaciologists just opened their eyes to studying glaciers about 150 years ago. We started to look at glaciers from different angles, perspectives, satellites — but we forgot to open our ears,” said Dr. Evgeny Podolskiy, an assistant professor at the Arctic Research Center at Hokkaido University in Sapporo, Japan. “I’ve been studying glacier geophysics for quite some time and I found that there is this kind of natural zoo, or a universe, of sounds which we kind of totally ignored until recently.”
