Imaggeo on Mondays: Moving images – Photo Contest 2016

Since 2010, the European Geosciences Union (EGU) has been holding an annual photo competition and exhibit in association with its General Assembly and with Imaggeo – the EGU’s open access image repository.

In addition to the still photographs, imaggeo also accepts moving images – short videos – which are also a part of the annual photo contest. However, 20 or more images have to be submitted to the moving image competition for an award to be granted by the judges.

This year saw seven interesting, beautiful and informative moving images entered into the competition. Despite the entries not meeting the required number of submissions for the best moving image prize to be awarded, three were highly ranked by the photo contest judges. We showcase them in today’s imaggeo on Mondays post and hope they serves as inspiration to encourage you to take short clips for submission to the imaggeo database in the future!

During a flight over the Caliente dome of Santiaguito volcano to collect images for photogrammetry, this explosion happened. At this distance, you can clearly see the faults along which the explosion initiates, although the little unmanned aerial vehicle is shaken quite a bit by the blast.

Timelapse video of Undulatus asperitus clouds over Disko Bay, West Greenland. This rare formation appeared in mid-August at the tail end of a large storm system that brought strong winds and exceptional rainfall. The texture of the cloud base is caused by turbulence as the storm passed over the Greenland Ice Sheet. The status of Undulatus asperitus is currently being reviewed by the World Meteorological Organisation. If accepted, it will be the first new cloud type since 1951.

Share the work you presented at EGU 2016: upload your presentations for online publication

This year it is, once again, possible to upload your oral presentations, PICO presentations and posters from EGU 2016 for online publication alongside your abstract, giving all participants a chance to revisit your contribution  hurrah for open science!

Files can be in either PowerPoint or PDF format. Note that presentations will be distributed under the Creative Commons Attribution 3.0 Licence. Uploading your presentation is free of charge and is not followed by a review process. The upload form for your presentation, together with further information on the licence it will be distributed under, is available here. You will need to log in using your Copernicus Office User ID (using the ID of the Corresponding Author) to upload your presentation.

Presentations and posters will be linked to from their corresponding abstracts. If your presentation didn’t have an abstract (this is the case for Short Courses and others), but you still want to share it with the wider community you can consider uploading your presentation to slideshare or figshare as a PDF to share it instead.

All legal and technical information, as well as the upload form, is available until 19 June 2016 at:

The final days of the mountain glaciers

The final days of the mountain glaciers

In 1896 British lawyer, mountaineer and author Douglas Freshfield climbed an obscure mountain in the Caucasus called Kasbek and in his book detailing his adventures he described the mountain:

“From this point the view of Kasbek is superb: its whole north-eastern face is a sheet of snow and ice, broken by the steepness of the slope into magnificent towers, and seamed by enormous blue chasms.”

D Freshfield (1986) The Exploration of the Caucasus, page 93

A photo of the mountain taken at the same time highlights the Gergeti glacier (called at the time the Ortsveri glacier) running down the centre of the image. In 2015 Levan Tielidze took another photo of the same view which highlighted a shocking change.

The photo above echoes photos taken of mountain glaciers from across the globe over the last 100 years. All these photos, when compared with their older counterparts, show the comprehensive retreat of mountain glaciers in every country. The retreat of mountain glaciers was called a ‘canary in the coal mine’ along with other indicators of global climate change. But new data presented this month at the European Geosciences Union General Assembly, shows us that that canary is now past saving.

Ben Marzeion, professor of Geography and Climate Science at the University of Bremen, has found that mountain glacier retreat (and eventual disappearance) is now inevitable. In a session relating to the Paris agreements (where 195 countries from around the globe agreed to work towards limiting global temperature change to two degrees) Marzeion presented evidence that indicates that even if that ambitious target were achieved, 60% of current mountain glaciers will still melt away. In fact the impacts of climate change are more severe than even this number suggests. Prof Marzeion explains:

‘Even if climate warming were to stop today – which is physically impossible – about one third of the glacial ice in the world would still melt in the long term.’

This is because the ice in the mountain glaciers responds to climate change with a time delay. Mountain ice is not sustainable and more than half of the ice in a mountain glacier is responding to temperature change that has already happened. The ice of the mountain glaciers has been melting for decades and once that process begins, it is very difficult to stop. Smaller glaciers and those at lower altitudes are at greater risk of complete loss, but Professor Marzeion says that any glacier where the summer snowline rises above the mountain peak will not survive. This has wider implications for water use in mountainous areas.

‘Saving the glaciers is an illusion in many mountain ranges,’ says Marzeion. ‘We will have to adapt to the consequences of glacier melt. This will affect the coastal regions of the world, but also populations in the mountainous regions, who will have one fewer source of water at their disposal in summer.’

Although the question of global temperature change is still one that we have to solve, it seems that our desire to take responsibility for our actions comes too late for those ‘magnificent towers’ and ‘blue chasms’ that Douglas Freshfield described over 100 years ago.
