Jasper National Park is the largest national park in the Canadian Rocky Mountains, spanning across nearly 11,000 square kilometres of Canadian wilderness. The park is known for its rugged landscape, extensive trails, and abundance of deer, bighorn sheep, wolves, mountain lions and bears. This region is also very susceptible to blazing wildfires, a result of human activity that began more than a ce ...[Read More]
Over the recent decades, the Arctic has warmed twice as fast as the whole globe. This stronger warming, called “Arctic Amplification“, especially occurs in the Arctic because ice, ocean and atmosphere interact strongly, sometimes amplifying the warming, sometimes reducing it. These interactions are called “feedbacks” and are illustrated in our Image of the Week. Let’s ...[Read More]
Oceans are “populated” by millions of specimens of microscopic organisms which constitute the phytoplanktonic communities (e.g. diatoms, dinoflagellates, cyanobacteria and coccolithophorids). These tiny organisms are important indicators of the “health” of present oceans and their remains constitute important tracers of past paleoenvironmental conditions. The ocean is in fact the oldest and larges ...[Read More]
We’ve all attended conferences with those dreaded 15-minute talks and we have no problem picking out which talks were amazing and which talks were abysmal. However, when it comes to our own talks, it’s hard to judge them, find out how they can be improved or break away from long-established habits (such as our layout or talking pace). This week, Matthew Herman, postdoc at the Tectonoph ...[Read More]
It’s not every day that you can peer into a volcano, much less gaze out at the sky from the inside of one. The Algar do Carvão, or “the Cavern of Coal,” is one of the few places on Earth where you can explore the underground reaches of a volcanic site. The volcanic pit is found on the island of Terceira, part of the Azores archipelago. This collection of islands is an autonomous region of Portugal ...[Read More]
Last year saw some of the biggest blazes in history, and may be a sign of things to come. 2017 was a record year for wildfires. California and neighboring western states saw the most destructive fire in US history, with an estimated 18 billion dollars worth of damage over the season. In central Portugal, fires caused 115 deaths over the same period. Researchers presenting at a press conference at ...[Read More]
![Fire, Fog, Frost, Famine – French Revolution? The Lakagígar eruption in Iceland, 1783-1784 [Part 1]](https://blogs.egu.eu/divisions/gmpv/wp-content/blogs.dir/19/files/2018/05/Figure1_southwestern_fissure_edit-700x400.jpg)
“On the 8th of June 1783, at Whitsun, there gushed forth from the mountains behind the summer pastures a fire which devastated land, cattle and humans with its effects, both nearby and far away”, wrote Reverend Jón Steingrímsson of Kirkjubæjarklaustur in his autobiography [2]. The “fire” which welled up from a volcanic fissure now known as Lakagígar (the craters of Mount Laki) was the biggest floo ...[Read More]

Geothermal heat flux is the major unknown when we evaluate the temperature and the presence/absence of water at the bed of the Antarctic Ice Sheet. This information is crucial for the Beyond Epica Oldest Ice project, which aims to find a continuous ice core spanning 1.5 million years (see this previous post). A lot of work has been done* to determine geothermal heat flux under the entire Antarctic ...[Read More]
On the plateau of Kilimanjaro, Tanzania, the remnants of a glacier can be found and the ice from that glacier contains a rather interesting feature – Broccoli! Not the vegetable, but bubbles that look a lot like it. Our Image of the Week shows some of these strange “Broccoli Bubbles”. Read on to find out more about where these were found and how we can see them. There is not much ice left on the m ...[Read More]
