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

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

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

By Albert Firus and Laurenz van Bonn (GEOMAR) Albert and Laurenz on board the R/V Sonne (Photo by: Tjark Andersch). As the SONNE leaves the first measurement station around the equator behind and continues further into the Bay of Bengal, technicians, scientists, and crew on board are quite busy. While for some this is almost routine, such as our technician Mario, who is on his 36th cruise already, others are gaining their first experiences on board of a research vessel these days. This includes the two students Albert (26, Geosciences) and Laurenz (21, Environmental Sciences). Albert is i ..read more

On the left picture from right to left: Rene Rabe, Dr. Arun Babu Suja, and Shravan Deshmukh. Greetings from the high seas by the TROPOS scientific team! Our mission during the BIOCAT-IIOE2 cruise is to delve into the fascinating world of atmospheric aerosols – those tiny particles suspended in the air – and unlock their secrets. These tiny particles suspended in the air hold immense significance in shaping our planet’s climate and ecosystems. Our mission is to unravel ..read more

Last year in summer I finished my Master’s degree. I was, and still am, very much in love with science, and enjoyed my research-focussed program a lot. No surprise that I wanted to pursue a scientific career, and that I was very happy I had managed to secure a PhD position as the next step down the academic road. I was on top of my game, I knew what I wanted, I was bursting with excitement, couldn’t wait to get started, I felt intelligent and capable and well-qualified for the job. And then bureaucracy happened. And it made me question everything – first and foremost my own intelligence and ca ..read more

In den letzten Blogeinträgen haben wir gruselig aussehende Tiefseefische, gallertartige Schönheiten und faszinierende mikroskopische Organismen gezeigt. Eine weitere häufige Organismengruppe, die wir während MSM126 gefangen haben und die bisher nicht im Rampenlicht stand, sind die Kopffüßer (Cephalopoden). Cephalopoden sind Weichtiere – wie Schnecken oder Muscheln – und gehören zu den Meeresbewohnern, die oft eine hohe trophische Position in den Nahrungsnetzen einnehmen. Während unserer Fahrt haben wir mit unseren Kamerasystemen Cephalopoden wie Tintenfische, Oktopoden oder Sepien entdeckt und ..read more

The last blog posts showed you scary-looking deep-sea fishes, gelatinous beauties and mesmerizing microscopic organisms. Another frequent organism group we captured during MSM126 which did not enjoy a spotlight so far are the cephalopods. Cephalopods are molluscs – like snails or mussels – and are marine inhabitants which often occupy high trophic positions in food webs. During our cruise, we encountered cephalopods such as squids, octopods or cuttlefish with our camera systems and also caught them frequently with our net gear. On board we deployed a multitude of net types. Nets with large ope ..read more

The past blog entries have shown you the breath-taking and beautiful works of the JellyWeb expedition: we have seen colourful critters, cutting edge technology and brave physicists alone amongst biologists. Our projects on MSM126 are quite diverse and besides all of them being quite exciting, they share one more trait: they all produce a ton of data. Data, that needs to be managed and curated. I am going to be honest: if I would visit a blog about a deep-sea biology expedition containing posts about the coolest organisms and equipment ever, I would probably skip the part about data management ..read more
