Surge-type glaciers are the bi-polar member of the family of glacier dynamics. Every now and then they go into a complete fury and nobody really understands why. What are surge-type glaciers? Surge-type glaciers typically go through what we call the “surge cycle”. It is divided into two phases; a long quiescent phase during which the glacier is more or less dormant, followed by much shorter phase ...[Read More]
Science communication has become a common focus of many aspects of academic research and teaching. Despite becoming more prevalent in recent years it has a long and deep rooted history, which goes hand in hand with scientific discovery. In this blog post, Sam Illingworth, gives a brief outline of the history of science communication. Science Communication is a phrase that seems to permeate into ma ...[Read More]
This is a guest post written by Jürgen Kusche, who has convened numerous sessions on various international conferences, and had the wonderful idea to use the geodesy division blog to initiate an open discussion on the topic session convening. For that reason, readers are encouraged to comment at the end of this post. Currently, Jürgen Kusche is professor at the Chair of Astronomical, Mathematical ...[Read More]
I don’t think it is any secret that the world is facing an imminent energy crisis. We are trying to generate more power than ever before, but at the same time, we now realize we have to do it in a sustainable way that does not harm the environment or exacerbate any existing issues such as climate change. The problem is these two goals are often mutually exclusive. Most of our power generatio ...[Read More]
Some aspects of Earth Science are truly interdisciplinary and this week’s Imaggeo on Mondays photograph is testament to that. The maiden voyage of the research cruise SA Agulhas II offered the perfect opportunity to combine oceanographic research, as well as climate science studies. Raissa Philibert, a biogeochemistry PhD student, took this picture of the daily release of a weather balloon by mete ...[Read More]
It’s dark. It’s always dark these days. Lights in the sky burn your eyes, so you keep your face to ground in the hopes that they’ll go away. But they don’t. The air is heavy. Heavy with poisons that make it difficult to breathe. Heavy with foreboding dread. You, my unfortunate friend, are going through a mass extinction! There have been five periods of mass extinction in the past. These represent ...[Read More]
This guest blog post is brought to you by Nick Arndt, Professor at ISTerre and convenor of the the Great Debate at last year’s General Assembly, Metals in our backyard: to mine or not to mine. During the Great Debate the issue of whether the environment impact of mining outweighs the benefits vs. domestic metal production was questioned. With Europe currently importing between 60-100% of the metal ...[Read More]
Everyday we come into contact with technology that has changed the way we work, live and even think. Yet it is still easy to forget how integral satellite technology is to our daily lives; over two thousand artificial satellites currently orbit our planet – satellites for navigation, for telecommunication, for meteorology, and for environmental and climate monitoring. The latter two categori ...[Read More]
Flo looks two examples of the strange and important ways that geology and where it’s located can affect international governance and regulation. From the presence of tiny coralline islands to ownership of the Arctic! I’ve always had an interest in the peculiarities of geology and geomorphology and the inordinate (sometimes almost absurd!) ways that they play their part in deciding on b ...[Read More]
After what has seemed like an eternity (or more than one post-doc post, which is essentially the same thing), I’ve got a new paper published. To commemorate this auspicious occasion, I’m going to write about it. The paper is published in Atmospheric Chemistry and Physics and is available open access here. The study investigated how aerosol particles can alter atmospheric chemistry duri ...[Read More]
