Imaggeo on Mondays: Symbiosis of ice and water

Imaggeo on Mondays: Symbiosis of ice and water

This mesmerising photograph is another of the fabulous finalists (and winner) of the 2017 imaggeo photo contest. Imaggeo is the EGU’s open access image repository. It’s a great place to showcase your photographs; so whether you are stuck in the lab this summer, frantically typing away at a paper, or are lucky enough to be in the field, be sure to submit your photographs for all EGU members to see. You never know, we might choose to feature it on the blog too!

This picture was taken at Storforsen, an impressive rapid in the Pite River in northern Sweden. That day, the sinking sun illuminated the whole area with warm reddish colors which formed a contrast to the remains of the long-lasting winter period. The rapid is located close to the site of a temporary seismological recording station which is part of the international ScanArray project. Within that project we focus on mapping the crustal and mantle structure below Scandinavia using a dense temporary deployment of broadband seismometers.

Imaggeo on Mondays: Nor’Wester in the Southern Alps of New Zealand

Imaggeo on Mondays: Nor’Wester in the Southern Alps of New Zealand

Stephan Winkler’s 2017 Imaggeo Photo Contest finalist photo showcases an unusual weather phenomenon…

The image shows a typical weather situation in the Southern Alps of New Zealand with a moist, westerly airflow pushing over the Main Divide [which separates the water catchments of the more heavily populated eastern side of the island from those on the west coast] to create a typical foehn wind [dry and warm winds which form on the downside of a mountain range] pattern (locally called Nor’Wester) in the region. Immediately west of this Main Divide, annual precipitation of up to 15,000 mm has been estimated.

The upper part of Tasman Glacier, as other glaciers around and immediately east of the Main Divide, receive impressive amounts of snow due to an overspill effect and can still be regarded as maritime.

In the image, however, the situation is displayed when right at the Main Divide the clouds disappear due to increasing temperatures when flowing over the Divide. The foehn wind developing with such weather pattern can be very strong. However, the image nicely shows how the glaciation of the central Southern Alps is influence by the availability of moisture and the dynamic character of the regional climate.

Announcing the winners of the EGU Photo Contest 2017!

The selection committee received over 300 photos for this year’s EGU Photo Contest, covering fields across the geosciences. Participants at the 2017 General Assembly have been voting for their favourites throughout the week  of the conference and there are three clear winners. Congratulations to 2017’s fantastic photographers!

Penitentes in the Andes by Christoph Schmidt (distributed by imaggeo.egu.eu). This photo was taken in the Bolivian Andes at an altitude of around 4400 m. The climatic conditions favour the formation of so-called penitents, i.e. long and pointed remains of a formerly comprehensive snow field.

Symbiosis of fire, ice and water by Michael Grund (distributed by imaggeo.egu.eu). This picture was taken at Storforsen, an impressive rapid in the Pite River in northern Sweden.

Movement of the ancient sand by Elizaveta Kovaleva (distributed by imaggeo.egu.eu). In the Zion National Park you can literally touch and see the dynamic of the ancient sand dunes.

Photo Contest finalists 2017 – who will you vote for?

The selection committee received over 300 photos for this year’s EGU Photo Contest, covering fields across the geosciences. The fantastic finalist photos are below and they are being exhibited in Hall X2 (basement, Brown Level) of the Austria Center Vienna – see for yourself!

Do you have a favourite? Vote for it! There is a voting terminal (also in Hall X2), just next to the exhibit. The results will be announced on Friday 28 April during the lunch break (at 12:15).
