From the tiny vibrations which travel through air, allowing us to hear music, to the mighty waves which traverse oceans and the powerful oscillations which shake the ground back and forth during an earthquake, waves are an intrinsic part of the world around us. As particles vibrate repeatedly, they create an oscillation, which when accompanied by the transfer of energy, creates a wave. The way in ...[Read More]

Geotalk is a regular feature highlighting early career researchers and their work. In this interview we speak to Federico Bianchi, a researcher based at University of Helsinki, working on understanding how clouds are born. Federico’s quest to find out has taken him from laboratory experiments at CERN, through to the high peaks of the Alps and to the clean air of the Himalayan mountains. His innova ...[Read More]

With the conference only a few weeks away here is a brief, and by no means comprehensive, introduction of how to get to Vienna and what to do when you’re there! Getting here Vienna’s International Airport is served by many of the major European airlines. If you would like to consider overland you’ll find more information on the General Assembly website. And, if you haven’t seen it already, make su ...[Read More]

Nestled among the high peaks of the Karakoram, in a difficult to reach region of China, lies Kyagar Glacier. It’s trident-like shape climbs from 4800 to 7000 meters above sea level and is made up of three upper glacier tributaries which converge to form an 8 km long glacier tongue. Until recently, it’s remoteness meant that studying its behaviour relied heavily on the acquisition of data by satel ...[Read More]
