Imaggeo on Mondays: The wonderful home of pink flamingos

This stunning photograph is another of the fabulous finalists 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!

Surrounded by sleeping and active volcanoes, Laguna Colorada is one of the mythical places of South-Lipez. Perched at more than 4000 meters on the Bolivian altiplano , this volcanic laguna owes its color to microscopic red bacteria which make the delight of pink flamingos.

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: Salt shoreline of the Dead Sea

Imaggeo on Mondays: Salt shoreline of the Dead Sea

This beautiful aerial image (you’d be forgiven for thinking that it was a watercolour) of the Dead Sea was captured by a drone flying in 100m altitude over its eastern coastline.

Climate change is seeing temperatures rise in the Middle East, and the increased demand for water in the region (for irrigation) mean the areas on the banks of the lake are suffering a major water shortage. As a result, the lake is shrinking at an alarming rate. Currently, it is shrinking by over 1m/year. The image was captured as part of a survey in the wider project DESERVE (Kottmeier et al. 2016) addressing the environmental changes accompanying the lake level drop.

In this case, the special focus is to look for e.g. submarine springs or other geomorphological evidence in the shallow lake water that can later turn into hazardous sinkholes (cf. recent publication on that topic Al-Halbouni et. al. 2017). Learn more about the environmental challenges and geohazard risks the region faces in this December 2016 Imaggeo on Mondays post.

The round features see in this image, nevertheless have been identified as salt accumulations following basically the sinusoidal shoreline.

The different colours of the lake indicate water of varying densities, e.g. fresh water floating on top of saltier water and possible sediments inside.

The shoreline appears with different colours each year depending on the sediment mud & evaporite material. Each line represents the retreat of a given year!

EGU geoscientists are out of this world!

EGU geoscientists are out of this world!

Space science has always been an exciting relative of the geosciences, and so it may come as no surprise that the woman who could become Germany’s first female astronaut attended the EGU General Assembly this year. Insa Thiele-Eich has made it to the final of Germany’s ‘Die Astronautin’ competition, which intends to send a German female astronaut to the International Space Station for a ten day research mission in 2020. She’s also a meteorologist and is currently finishing up a PhD on flooding in Bangladesh.

Insa wasn’t the only Die Astronautin competitor exhibiting at EGU and was joined by several female geoscientists who took part in the contest. Liv Heinecke and Sandra Tippenhauer also made it into the final rounds of the tough competition while juggling careers as geoscientists. Liv is coming to the end of her PhD on lake sediments in the Pamir Mountains in Tajikistan, while Sandra researches physical oceanography and the effect on ocean biology.

We caught up with them at the EGU booth to find out about why they applied to be an astronaut and how their experiences of geoscience influenced their decision.

What made you apply to Die Astronautin?

Insa: It’s been a dream for me, as I think for all of us, we’ve been wanting to do this for so long that I don’t think anybody was surprised that any of us applied- for my family is was more like ‘oh ok- you finally had the opportunity’

Liv: The call was for scientists and engineers- STEM women- and I thought ‘yep, that sounds pretty cool!’ They asked for outdoor experience and usually in our field we go into the field- to Siberia, Antarctica- something like that. So you need to be adventurous, excitable and you need to love your work. It is also encouraging girls to go into STEM. I have two kids and I don’t ever want anyone to tell my daughter she can’t get a Nobel Prize in physics.

Sandra: I always wanted to be an astronaut since, I don’t know when! It made me think want I would do [to be an astronaut] so I decided to go into science. I really love my job in science; I always want to know how things work so studying physics was the right decision. I also work with the earth to try and understand how things work- at the moment I apply it to the oceans. I love the ocean and I live really close to it so I can go out and immediately see what I’m working with! But I also love space and I’d love to do science in space.

What was the application process like?

Insa: Initially there were 409 applicants, which were reduced to 120 and asked to fill out a medical questionnaire. Then 90 were invited to go to Hamburg for the first stage of cognitive testing, so that was maths, physics, memory span and a lot of other cognitive tests. And from those 90 we were reduced to 30, who continued on.

Then it was five days in groups of six. That was more group psychological testing and a psychological interview about yourself and how you work in a team as teamwork is essential. I think that’s where being a geoscientists, always having to go out and do fieldwork, really helps. You’re usually in a stressful situation because you (usually) have little funding, or you have to perform now because you can’t do it again. You have to cooperate; you’re often jetlagged with little sleep! So it really helps!

Also working in an international field, for me at least, has helped. You know- stay calm, assess, does everyone know what we’re talking about here? As everyone’s from different background, especially when you do interdisciplinary work you have to be a very good team player.

I just wanted to add that there are so many geoscientists that applied that we actually agreed to meet at EGU. I know at least of eight in addition to myself, but it’s probably even more- so I thought that was pretty amazing.
