The best of Imaggeo in 2015: in pictures

The best of Imaggeo in 2015: in pictures

Last year we prepared a round-up blog post of our favourite Imaggeo pictures, including header images from across our social media channels and Immageo on Mondays blog posts of 2014. This year, we want YOU to pick the best Imaggeo pictures of 2015, so we compiled an album on our Facebook page, which you can still see here, and asked you to cast your votes and pick your top images of 2015.

From the causes of colourful hydrovolcanism, to the stunning sedimentary layers of the Grand Canyon, through to the icy worlds of Svaalbard and southern Argentina, images from Imaggeo, the EGU’s open access geosciences image repository, have given us some stunning views of the geoscience of Planet Earth and beyond. In this post, we highlight the best images of 2015 as voted by our Facebook followers.

Of course, these are only a few of the very special images we highlighted in 2015, but take a look at our image repository, Imaggeo, for many other spectacular geo-themed pictures, including the winning images of the 2015 Photo Contest. The competition will be running again this year, so if you’ve got a flare for photography or have managed to capture a unique field work moment, consider uploading your images to Imaggeo and entering the 2016 Photo Contest.

Different degrees of oxidation during hydrovolcanism, followed by varying erosion rates on Lanzarote produce brilliant colour contrasts in the partially eroded cinder cone at El Golfo. Algae in the lagoon add their own colour contrast, whilst volcanic bedding and different degrees of welding in the cliff create interesting patterns.

The Grand Canyon is 446 km long, up to 29 km wide and attains a depth of over a mile 1,800 meters. Nearly two billion years of Earth’s geological history have been exposed as the Colorado River and its tributaries cut their channels through layer after layer of rock while the Colorado Plateau was uplifted. This image was submitted to imaggeo as part of the 2015 photo competition and theme of the EGU 2015 General Assembly, A Voyage Through Scales.

Svalbard is dominated by glaciers (60% of all the surface), which are important indicators of global warming and can reveal possible answers as to what the climate was like up to several hundred thousand years ago. The glaciers are studied and analysed by scientists in order to better observe and understand the consequences of the global warming on Earth.

Antelope slot canyon is located on Navajo land east of Page, Arizona. The Navajo name for Upper Antelope Canyon is Tsé bighánílíní, which means “the place where water runs through rocks.”
Antelope Canyon was formed by erosion of Navajo Sandstone, primarily due to flash flooding and secondarily due to other sub-aerial processes. Rainwater runs into the extensive basin above the slot canyon sections, picking up speed and sand as it rushes into the narrow passageways. Over time the passageways eroded away, making the corridors deeper and smoothing hard edges in such a way as to form characteristic ‘flowing’ shapes in the rock.

Beautiful Sarez lake was born in 1911 in Pamir Mountains. A landslide dam blocked the river valley after an earthquake and a blue-water lake appeared at more than 3000 m over sea level. However this beauty is dangerous: local seismicity can destroy the unstable dam and the following flood will be catastrophic for thousands Tajik, Afghan, and Uzbek people living near Mugrab, Panj and Amu Darya rivers below the lake.

Layer upon layer of sand, clay and silt, cemented together over time to form the sedimentary units of the Badlands National Park in South Dakota, USA. The sediments, delivered by rivers and streams that criss-crossed the landscape, accumulated over a period of millions of years, ranging from the late Cretaceous Period (67 to 75 million years ago) throughout to the Oligocene Epoch (26 to 34 million years ago). Interbedded greyish volcanic ash layers, sandstones deposited in ancient river channels, red fossil soils (palaeosols), and black muds deposited in shallow prehistoric seas are testament to an ever changing landscape.

Mountain glaciers are known for their high sensitivity to climate change. The ablation process depends directly on the energy balance at the surface where the processes of accumulation and ablation manifest the strict connection between glaciers and climate. In a recent interview in the Gaurdian, Bernard Francou, a famous French glaciologist, has explained that the glacier depletion in the Andes region has increased dramatically in the second half of the 20th century, especially after 1976 and in recent decades the glacier recession moved at a rate unprecedented for at least the last three centuries with a loss estimated between 35% and 50% of their area and volume. The picture shows a huge fall of an ice block of the Perito Moreno glacier, one of the most studied glaciers for its apparent insensitivity to the recent global warming.

The picture was taken in Salina Turda, a fascinating salt mine in western Transylvania, in Durgău – Valea Sarată near Turda city. In the picture, the pockets created by salt dissolution can be observed. Over time, due to the erosive power of air currents, the walls have been reshaped: the corners have been rounded and, at the contact between the roof and the walls, a series of dissolution pockets form. The pockets are created by the effect of the water, found in the moist atmospheric air, which enters the underground cavern. At the base of the walls a consistent layer of recrystallized salt forms due to the slow trickling down of the condensed vapor a long the walls.

Salt deposits from Transylvania belong to an evaporitic horizon overlaid on the entire surface of the basin. Recent geological research enforces the idea that the leading cause for salt precipitation was the isolation from the Pannonian Basin of the Transylvanian Basin; an isolation which took place during the latest Badenian sea-level low stand (some 13.6 to 13.4 million years ago), in a warm and wet climate, not too dissimilar to the modern-day Mediterranean climate.

It is thought that the exploitation of the salts deposits began during the Roman occupation in Dacia, but the first written documents that mention systematic exploitation of the mine by means of underground mining date back only to 1271.

Turda salt mine ceased activity in 1932. During World War II the mine was used as a bomb shelter. In addition, between 1948-1992, the Franz Josef gallery was used as a storeroom for cheese. In 1992, the salt mine opened its doors to tourists.

The mine has a unique microclimate; characterized by temperature ratings in the 11-12 ° C, relative humidity is about 80% and air pressure between 747-752 mmHg. Air ionization at moderate levels and the lack of pathogenic bacteria contribute to the curative effect of respiratory diseases.

There are even more benefits to choosing a PICO session at EGU 2016!

There are even more benefits to choosing a PICO session at EGU 2016!

Some of the sessions scheduled for the upcoming EGU General Assembly are PICO only sessions. This means that, rather than being oral or poster format, they involve Presenting Interactive COntent (PICO). The aim of these presentations is to highlight the essence of a particular research area – just enough to get the audience excited about a topic without overloading them with information.

PICO sessions start with a series of 2 minute long presentations – one from each author. They can be a Power Point, a movie, an animation, or simply a PDF showing your research on a display. After the 2 minute talks, the audience can explore each presentation on touch screens, where authors are also available to answer questions and discuss their research in more detail.

This format combines the best of oral and poster presentations, allowing researchers to stand up and be recognised for great research while giving an oral contribution as well as discussing their work in detail and network with other participants. This year we are also making a few improvements to the layout of the PICO presentation areas in the large halls to minimise noise disruption to presenters.

An exciting development for the 2016 General Assembly is that PICO presentations are now included in the Outstanding Student Poster Awards (as they were formerly known), and have now been renamed to Outstanding Student Poster and PICO (OSPP) Awards.

The aim of the award is to improve the overall quality of poster and PICO presentations and most importantly, to foster the excitement of early career scientists in presenting their work. To be considered for the OSPP award, you must be the first author and personally present the PICO at the conference, as well as satisfy one of the following criteria:

  • being a current undergraduate (e.g., BSc) or postgraduate (e.g., MSc, PhD) student;
  • being a recent undergraduate or postgraduate student (conferral of degree after 1 January of the year preceding the conference) who are presenting their thesis work.

Entering couldn’t be easier! Make sure you nominate yourself when you submit your abstract on-line. You’ll receive a letter, known as ‘Letter of Schedule’, confirming your presentation has been accepted, which will also include a link by which to register for the award. Before the conference, make sure you include the OSPP label (which you can find here) to your PICO presentation header so that the judges of the OSPP award now to evaluate your presentation.

To learn more about PICO presentations see the General Assembly website. You can also check out the short introductory video below:

Showcase your film at Geocinema at the 2016 General Assembly!

Showcase your film at Geocinema at the 2016 General Assembly!

Every year, we showcase a great selection of geoscience films at the EGU General Assembly and after six successful years we will again be running Geocinema in 2016. If you’ve shadowed a scientist in the lab, filmed fantastic spectacles in the field, or have produced an educational feature on the Earth, planetary or space sciences, we want to hear from you.

Geocinema features short clips and longer films related to the geosciences, and from animations to interviews, all films are welcome. If you would like to contribute to this popular event, please fill out the submission form by 4 January 2016.

This year, in line with the theme of the EGU 2016 General Assembly, we particularly encourage submissions representing the conference theme: Active Planet. If your film highlights the conference theme, please indicate this in the submission form.

To get a feel for what we have screened in previous years, take a look at the online archive, with films that explore all facets of geoscience – from ocean depths to outer space.

Suitable films will be screened at the Geocinema room during the EGU 2016 General Assembly in Vienna (17–22 April 2016). Note that you must be able to provide us with an electronic or DVD version of your film and you must have appropriate permission to show the feature in a public venue. Multiple submissions from the same person are welcome. Films must be in English or have subtitles in English, since it is the language of the conference. Multiple submissions from the same person are welcome.

For more information, please send us an email or get in touch with our Communications Officer Laura Roberts.
