On the traces of the ocean's history

In January 2016 BASE-LiNErs have successfully carried out a field trip to La Palma, Canary Islands, Spain in order to collect Pajaudina atlantica Logan, 1988 for cultivation under laboratoy conditions at GEOMAR. Pajaudina atlantica is endemic to the Canary Islands and is recorded from overhangs and caves in shallow waters as well from deep sea habitats.

The cultivation of Paujaudina atlantica starts

In Januray, 2016 the cultivation of Pajaudina atlantica Logan, 1988 started at the facilities of GEOMAR, where BASE-LiNE Earth investigates the incorporation (partition coefficient) during growth of certain redox sensitive elements in cultured and living brachiopods to also better understand the inherent biomineralization processes and mechanisms, which will enable us to apply the trace element and isotope systems to fossil archives.

A hunt for Palaeozoic brachiopods

In May 2016 BASE-LiNE Earth researchers participated on a ten-day fieldtrip with the aim to find Devonian and Carboniferous brachiopods which can be used for geochemical analyses.
Collection locations include fossil sites in Indiana, Pennsylvania, Ottawa and multiple sections in central New York State. During the successful fieldwork, hundreds of brachiopod specimens and multiple fossil gastropods and bivalves were collected. Stable isotope and clumped isotope measurements will be obtained in order to study the diagenetic processes that could have affected the shells. The data can be then used to help the reconstruction of the Phanerozoic sea temperatures from the best preserved specimens.
The samples are available to all researchers of the BASE-LiNE Earth consortium and from outside institutions as well, upon request.

BASE-LiNE Earth Field Trip — Review

As part of the BASE-LiNE Earth program, ESRs made a field trip in June to collect brachiopod samples in the Karavanke Alps of Austria/Slovenia to add to the collaborative project collection. Furthermore, and perhaps more importantly, the field trip served as an excellent team building activity which also allowed ESRs to collaborate scientific ideas and put their own projects into a broader context within the BASE-LiNE Earth network.

Leading the trip was BASE-LiNE Earth partner, Dr. Albrecht Leis along with a colleague and expert in the regional geology of Carinthia, Dr. Walter Poltnig from the Joanneum Research.  

Prior to the official beginning of the trip itself, ESRs were given the opportunity to make a visit to the light isotope laboratories of the Joanneum Institute and a tour of the facilities of the Institute of Applied Geosciences at the Graz University of Technology. This allowed the students to familiarize themselves with the laboratories and equipment which will be available for their potential future use within their projects.

The field trip left Graz on the 7th of June, starting with a walk up a local hill Gösting where ESRs observed brachiopod containing Devonian limestones. Unfortunately, the brachiopods were too highly altered to be of use for analytics, however were placed within a geological context to start familiarizing ESRs with Phanerozoic sedimentary geology of the Styrian region. In the evening a coach was taken to Bad Eisenkapppel in Carinthia, which would serve as a base for the remaining days to explore the Geopark Karavanke, sharing its name with the mountain range of the region.

On the second day of the trip ESRs ascended the mountain Hochobir. Once reaching the peak of Hochobir, Dr. Walter Poltnig gave a talk on the regional geology explaining features observable from the vista. After descending from the peak of Hochobir, ESRs spent time examining exposed fossiliferous Triassic Carbonate “Raibl” beds. Brachiopods found within this unit were collected for future analysis and potential use within the respective BASE-LiNE Earth projects.

For the final day of the trip on the 9th of June, ESRs crossed the border into Slovenia to visit the decommissioned Mežica lead-zinc mine situated within Triassic Carbonates. Geology of the mine and surrounding region were explained to the ESRs followed by a kayaking tour of the flooded lower levels of the mine. This was a truly unique experience which provided a novel way to explore the geology of the mountain. Upon exiting the mine, the trip went back to Graz where it ended with a fairwell dinner.

The field trip was successful with its goal of collecting brachiopod samples and strengthening relationships between project members, moreover it was fun and educational, receiving some very positive feedback from those who were involved.

Student internship or dipping a toe in Marine Sciences

"Hello! My name is Lena Schegerer. I am 16 years old and I am a student in grade 10 at the Gymnasium Thomaeum in Kempen, North Rhine-Westphalia. My favorite subject is biology since a long time and I am particularly interested in ecology. I was always keen on to learn more about the sea and how the life on earth is connected with the ocean. Furthermore, I want to get an idea on how researchers really work on how their day-to-day work looks alike, since so far I only know it from TV documentaries.

In order to do so I got in contact with Dr. Daniela Henkel, who offered me the possibility to get an introduction into the research carried out at GEOMAR. In addition to this I dipped into the world of coral reef ecology and gained knowledge on how scientists use fossils in order to reconstruct the history of our ocean. I also learned that the latter can help to give predictions for our future especially in context with climate change. From August 8th to 19th, 2016 I completed my student internship at GEOMAR."

From Kassel to Kiel for an appointment with Magellania venosa and Pajaudina atlantica

Getting information on living brachiopods is not an easy task. That at least is what Peter-Joachim Focke experienced when he started his search for details on recent brachiopods in December 2016. Mr Focke is a former teacher and got now involved at the adult education center in Kassel. In this context he is giving a seminar on the “White Jurassic”, for which is he collecting as much information as possible. His search ended on 6-7 January, 2017 with a visit at the GEOMAR facilities in Kiel, where brachiopods are cultured as part of a scientific project, which is funded by the European Union. During his visit Mr. Focke got insights into both the research tasks of BASE-LiNE Earth and the European Union as a funding source for research in Germany.

See you again in Kiel....

"To verify my ideas of the subject of my studies I was positively amazed to get the chance to go to the GEOMAR for one week and have a look over many shoulders, learn something about new methods and meet people working on fields I want to do research on when I finish my studies.

So the GEOMAR turned out to be the ideal place to learn about research done in marine ecosystems and methods to reconstruct the environment millions of years back in time. Spending most of my time with the PhDs of BASE-LINE Earth, I was given an insight in a huge variety of methods to collect data for different purposes.

We measured boron isotope ratio in permian brachiopod shells using columns filled with special resin to separate the boron from other elements of the shell after treating the sample with acid and H2O2 to get rid of all organic molecules. We finally took measurements with the mass spectrometer to get the acquired data.

I got the chance to take in situ measurements for calcium concentration in a saltwater aquarium containing a coral reef biosphere where isotopic ratios concerning CO2 were taking place.

I was given a briefing in the preparation process of instruments used during expeditions offshore.

I had the unique chance to experience science work in different laboratories, using various methods, instruments and machines to have a deeper insight in the wonderful marine environment.

I want to heartly thank everyone who guided me, answered my questions and assured me in my plans to study geosciences and chemistry. A special thank you to my great organisor Dr. Daniela Henkel. She truly did everything possible to give me an insight in almost every section and research group working in the GEOMAR." Stephan Hamisch, May 2017

BASE-LINE Earth on the trail of Marie Skłodowska-Curie

The Institute of Paleobiology/ Polish Academy of Sciences (PI Aleksandra Bitner) hosted the 1stWork Package Meeting (#1). In the framework of the meeting BASE-LiNE Earth ESRs had the chance to present their recent findings to the colleagues of their Work Package and beyond. The meeting was a perfect chance to intensively discuss scientific issues and modify individual roadmaps for the last project period.

Furthermore, BASE-LiNE Earth went on the trail of Marie Skłodowska-Curie, and by doing so we became aware of the luck we have to indeed live the European research dream...

BASE-LiNE Ear attended course “Large Igneous provinces and their environmental impacts”

Hana Jurikova (ESR10, GEOMAR) attended an intensive course organised by Prof. Henrik H. Svensen (Centre for Earth Evolution and Dynamics – CEED) and the DEEP Research School at University of Oslo.

This is what Hana reported:

"From September 11 - 15 2017, I participated in an intensive course on large igneous provinces (LIPs) at the University of Oslo. This was an excellent course, where we had the opportunity to learn in depth about various aspects of LIPs (from their formation, evolution to their link to Earth crises, mass extinction events to their role in shaping the Phanerozoic climate) from some of the leading experts."

BASE-LiNE Earth represented at the European Researchers`Night in Eckernförde, Germany

On September 29th, 2017 BASE-LiNE Earth took part in the European Research’s Night for the second time. From 5p.m. on BASE-LiNE Earth Researchers presented project related science such as the first brachiopod model showing the construction of the shell as well the providing insights into the inner parts of this unknown taxon. We also presented a model that translates the complex language of isotope fractionation in a plain language. All this was framed by shorts explaining the story behind BASE-LiNE Earth and introducing the people who are conducting the research.

3rd Workshop BASE-LiNE Earth was held in Graz, Austria

From October 2nd  to October 7th, 2017 the 3rd BASE-LiNE Earth Workshop on " Turning back the past – New views from proxies for early earth history and evolution of life on Earth ?" (see Workshop program here) was held at the Technical University in Graz, Austria (PI: Prof. Martin Dietzel).

In the framework of the 3rd Workshop more than 54 participants came together, which were BASE-LiNE Earth fellows, PIs, partners as well as external guests.

WP3 Meeting in Copenhagen

Work Package 3 meeting in Copenhagen
For two days in February 2018 we met in Copenhagen to discuss topics that we found especially important for our research. This short workshop was organised by PhD students to have a chance to get answers to scientific questions that arose during their PhD. Prof. R. Frei, the head of the geochemistry lab at the University of Copenhagen, opened the workshop and introduced us to how the chromium isotope composition of shells can be used as a proxy for redox conditions. Afterwards, two invited lecturers from the University of Graz, Prof. M. Dietzel and Dr. V. Mavromatis talked about the processes that influence the trace element, as well as the oxygen and carbon stable isotopic composition of carbonates. After the lectures we had dinner together and further discussed what we learned that day. The following day we visited Stevns Klint, the world-famous UNESCO World Heritage site where the Cretaceous/Paleogene boundary is the best exposed in the world. Our guide, F. Surlyk, who is well known for his research on these strata, introduced us to the local geology and to the environmental changes that occurred in the wake of the asteroid impact that killed the dinosaurs. Altogether, this meeting was useful to widen our knowledge in biomineralization processes and spark possible future collaborations.

BASE-LiNE Earth at EGU 2018

BASE-LiNE Earth was involved in various kinds of contributions at the European Geosciences Union EGU, that took place from 8-13 April 2018 in Vienna. Apart from scientific presentations such as orals and posters, BASE-LiNE Earth contributed in different workshops and sessions. Furthermore, the PICO (OSPP) poster award from 2017 was officially handed over to Sara Garcia Milner. For more details on all EGU activities related to BASE-LiNE Earth please follow here.

BASE-LiNEs at the 3rd International Meeting of Early Researchers in Paleontology

From the 18 th to the 21st of May Tamás Müller and I attend the International Meeting of Early Researchers in Paleontology that was held this year in Krasiejów (Poland). We experiecnes four very intensive days of talks, very interesting keynotes and a great opportunity for networking. Everything organized by young researchers and supported by different organizations and institutions. The meeting was in the Science and Human Evolution Park and we had the opportunity to visit the famous Jurapark of Krasiejów (Maria de Mar Simonet Roda)

BASE-LiNE Earth at the "Kieler Woche" 2018

It is the largest sailing event in the world and - with more than 3 million visitors - the largest summer festival in Northern Europe - the Kieler Woche. Is this a perfect place to present BASE-LiNE Earth to the people? Yes it is… With our touring exhibition, which consists of a model of Magellania venosa, a model that explains the complex process of isotope fractionation, and different video and poster material, the BASE LiNE Earth team provided vivid insides into the world of brachiopods and how these little guys can help us to gain knowledge on how the oceans looked hundreds of million years ago.

BASE-LiNEr is Monitoring of the status of coral reefs, and the influence of anthropogenic activity in coastal areas using Delta Ray Connect

Danijela Smaigl, ThermoFisher Scientific vistited Eilat, Israel from June 17th to 5th of July, 2018. This is what Danijela reported:

In one of the last stages of the project, we tested our system in The Eilat Nature Reserve Reef. Fieldwork was done in cooperation between Thermo Fisher Scientific, GEOMAR and Israeli partners of BASE-LiNE Earth project, Prof. Boaz Lazar from The Hebrew University of Jerusalem and Tanya Rivlin from The Interuniversity Institute for Marine Sciences in Eilat.

During fieldwork, we conducted high temporal resolution measurements of air and seawater from reef’s lagoon. Our experiments showed that this method can be used as a sensitive method for diagnosing the status of coral reefs and as a reliable tool to indicate specific biochemical processes in the water, e.g. photosynthesis and respiration.

Altogether, it was an amazing experience to work in such environment.

Toulouse welcomes ESOF 2018

This article is more of personal nature, but I feel that especially at the current time of change and uncertainties this kind of statement makes sense.

When I told a friend that I am going to Toulouse in order to attend the ESOF she asked me what ESOF means and why I am participating? The meaning is easy: ESOF stands for EuroScience Open Forum and is defined   as:  “… is the largest interdisciplinary science meeting in Europe. It is dedicated to scientific research and innovation and offers a unique framework for interaction and debate for scientists, innovators, policy makers, business people and the general public.”(https://www.esof.eu/en/about-ESOF.html) . Ok this is clear. But what does ESOF mean to me? What would I say if I would have to convince a colleague to spend one week in a European city listening to presentations such as: “What would it take to regrow an arm?” or “Ethics, social values and artificial intelligence?”  or  “Gender balance in Science, Technology, Engineering & Maths (STEM): Why do girls ignore computer science?”. My answer would be ESOF is a place where you can discuss scientific issues, to which you would hardly have access without attending ESOF. I would say that ESOF is a place where scientists, stakeholders, policy makers and others come together and discuss scientific findings, yes of cause, but it is more than this. It is a platform where people from Europe and beyond are coming together - no matter of where they are from in terms of geography and scientific background. I see ESOF as a tool for bringing people from a broad field of interests together, who have one thing in common: living the European idea and share it with the public. The next chance for doing so is in 2020 in Trieste. So come and join!


The first ...

We are very happy and proud to announce that the first BASE-LiNEr has submitted her thesis on "Boron element and isotope composition of Phanerozoic brachiopods - implications for the marine carbonate cycle". We are looking forward to follow your story... All the best and good luck!!!!!!!!!!!!!!


4th and final workshop BASE-LiNE Earth  ...

The 4th and final BASE-LiNE Earth Workshop was dedicated to both looking back to almost four years of BASE-LiNE Earth and to implement achieved tasks in visions and ideas for a life after BASE-LiNE. This year the event was hosted by our partner Prof. Lucia Angiolini at the venerable University of Milan, where more than 40 participants came together, BASE-LiNE Earth fellows, PIs, partners as well as external guests. It was a great meeting at a wonderful venue!

Mats Ippach succussfully completed his BSc within BASE-LiNE Earth

Hi, my name is Mats Ippach and I am an undergraduate student at the Christian Albrechts University of Kiel. I have had the opportunity to work on my Bachelor thesis entitled “A biomineralization model for incorporation of trace elements into brachiopods” within the framework of the BASE-LiNE Earth ITN supervised by Dr. Hana Jurikova at GEOMAR, Kiel. This was a very enriching experience as I have got the chance to get involved with the brachiopod culturing experiments, sample collection and preparation, Quadrupole-ICP-MS analyses and evaluation of the results. Thanks to this, I became more familiar with the entire process of scientific work. My thesis especially deals with the evaluation of trace element data to comprehend the underlying mechanisms for their incorporation into brachiopod shells. Using these data I developed a biomineralization model for brachiopods, which helps us to understand their biomineralization processes as well as describes the basis behind the use of trace elements for proxy applications. I’m thankful for the opportunity to play my part in such an exciting project with great people!

The abstract of my Bachelor thesis is available here.
