von Dr. Birgit Quack, GEOMAR Helmholtz-Zentrum für Ozeanforschung Kiel Es gibt zwei Bereiche in unserer Atmosphäre, in denen das Spurengas Ozon besonders wichtig ist: in der Stratosphäre und in der Grenzschicht an der Erdoberfläche. In der oberen Region unserer Atmosphäre, der Stratosphäre, entsteht Ozon durch den Zerfall von Sauerstoff im Sonnenlicht und wirkt als wichtiger UV-Strahlenschutz für das Leben auf der Erde. Es wird durch Radikalreaktionen von Halogenen wie Chlor, Brom und Jod, die in verschiedenen Formen in unserer Atmosphäre vorkommen, rasch zerstört. In den 1980er Jahren trat ei ..read more

Hallo halos in and over the Bay of Bengal

by Dr. Birgit Quack, GEOMAR Helmholtz Centre for Ocean Research Kiel There are two regions of our atmosphere where the trace gas ozone is especially important: in the stratosphere and in the surface boundary layer. In the upper region of our atmosphere, the stratosphere ozone is produced from the sunlit decay of oxygen and acts as an important UV radiation protector for life on earth. It is rapidly destroyed by radical reactions of halogens, such as chlorine, bromine, and iodine, which occur in various forms in our atmosphere. A severe ozone hole occurred in the 1980s and could be related to l ..read more

From Hypatia to Marie Tharp – Some women you should know

This blog post was inspired by the books “Forces of Nature – The Women who Changed Science” by Anna Reser and Leila McNeill and “Women in Science – 50 Fearless Pioneers Who Changed the World“ by Rachel Ignotofsky. Both shed light on a wide variety of women in science and their contributions. Here, I was only able to pick a few of them I found especially impressive, or relevant to marine sciences. Let me introduce you to a few of my heroines! Hypatia Hypatia lived approximately 350/370 – 415 AD in Alexandria, Egypt, which was part of the Roman Empire at the time. She was teaching astronomy and ..read more

by Qingwen Zhong (edited by Riel Ingeniero) I am a PhD student in physical oceanography. SO305 is my second research cruise in the eastern Indian Ocean, but I feel like everything seems new to me, and I am learning a lot from everyone on this cruise. Honestly, this whole experience has been nothing short of a highlight in my life. Deployment of CTD-Rosette on 8 May 2024 (Photo: Riel Ingeniero) If you happen to have some free time, consider dropping by the CTD lab and chat with the CTD team during their shift. The CTD team is always delighted to have visitors and engage in discussions about the ..read more

Isotopes – a multitool of biogeochemistry and how we use them on SO305

by Dr. Gesa Schulz Group photo of scientists from the University of Hamburg— Leandro Nazzari, Tjark Andersch, and Dr. Gesa Schulz. (Photo by Riel Ingeniero and Isabell Schlangen) Isotopes are atoms of the same element with the same number of protons but different numbers of neutrons in the atomic nucleus. Therefore, isotopes differ in their atomic mass.  They are divided into stable isotopes and unstable isotopes, with the latter exhibiting radioactive decay over time. The analysis of stable isotopes is a frequent used tool in the natural sciences, as it allows to determine sources an ..read more

(Photo by Tjark Andersch)   When the other scientists or the crew of the SO305 walk past the door of “Dry-Lab II”, they often wonder about the interesting outfits worn by us – Martha, Anja and Albert. Our laboratory itself also looks different from the other laboratories on board the SONNE. This is because we have set up a “clean room tent” in our lab with the help of plastic sheeting and an air-filtering laminar f ..read more

von Isabell Schlangen Willkommen zurück auf unserem Ozean-Wissenschafts-Blog! Heute tauchen wir in die faszinierende Welt des Kohlenstoff- und Stickstoff-Kreislaufs im Golf von Bengalen. Uns beschäftigt vor allen Dingen, die folgenden Fragen: Wie eng sind diese Prozesse miteinander verbunden? Wie hat sich die Biogeochemie dieser Region geformt? Und wie wirkt die Sauerstoffminimumzone (OMZ) auf beide Kreisläufe? Gut zwei Wochen nach unserer Abreise aus Colombo haben wir uns nicht nur mit dem Schiff und seiner Besatzung vertraut gemacht, sondern gleichsam mit dem Probenentnahmeverfahren. Das Erg ..read more

Unraveling the Mysteries of Carbon and Nitrogen in the Bay of Bengal

by Isabell Schlangen Welcome back to our Ocean Science Blog! Today, we’re delving into the fascinating world of carbon and nitrogen cycling in the Bay of Bengal, and how these processes are intimately connected in shaping the biogeochemistry of this region, particularly within the oxygen minimum zone. Almost two weeks after leaving Colombo, we’ve become familiar with the ship, the crew, and the sampling procedures. The team has already amassed several boxes of samples and conducted two significant incubation experiments. While this isn’t Lubrinas, Victors, Mats and Isabells’ first time on a re ..read more

von Albert Firus und Laurenz van Bonn (GEOMAR) Albert und Laurenz an bord des F/S Sonne (Foto: Tjark Andersch). Während die F/S SONNE die ersten Messstationen rund um den Äquator hinter sich lässt und weiter hineinfährt in den Golf der Bengalen, haben Techniker*innen, Wissenschaftler*innen und Crew an Bord alle Hände voll zu tun. Während das für die einen schon fast Alltag ist, wie zum Beispiel für unseren Techniker Mario, der bereits zum 36. Mal bei einer Forschungsfahrt dabei ist, sammeln andere in diesen Tagen ihre allerersten Erfahrungen an Bord eines Forschungsschiffs ..read more
