Geschrieben von: Jakob Lang Was machen GeowissenschaftlerInnen auf einem Schiff und wie bekommen sie eigentlich ihre heißgeliebten Gesteine? Was ist eigentlich eine Dredge und wie geht es mit den Steinen weiter? Eine kurze Einführung in die Beprobung des Ozeanbodens. Hier an Bord der R/V Sonne können wir schlecht mit Hammer und Kompass ins Gelände gehen, […]
What do geoscientists do on a ship and how do they get their precious rocks after all? What is a dredge and how are the rocks processed on board? A short introduction into seafloor sampling.
Die Wissenschaft hat viele Formen. Man kann Stunden im Labor verbringen und Experimente durchführen, vor dem Computer sitzen und Modelle entwickeln oder in aller Ruhe vor einem leeren Blatt Papier seine Gedanken sammeln. Aber manchmal bedeutet Wissenschaft auch, in die Welt hinauszugehen und seine Ideen zu testen. Genau darum geht es bei der Expedition SO307. […]
Science takes many forms. You can spend hours in the lab running experiments, sit in front of your computer building models, or gather your thoughts quietly in front of a blank piece of paper. But sometimes, science means going out into the world to test your ideas. That’s exactly what Expedition SO307 is all about. […]
When in January 2020 I started my PhD in Plant Ecology, I felt a mix of enthusiasm and anxiety. I knew the journey I was beginning would be arduous, and that was even before the several events that ended up making it even tougher than I expected. What follows is a recap of perhaps the […]
To unveil the ecological niche of pelagic top predator megafauna such as beaked whales, sperm whales and dolphins (but also seabirds, sharks, tuna and billfish), it is vital to know more about the prey they feed on, such as mid-water fish and cephalopods. These often lilliputian oceanic micronekton (with jellyfish and shrimp) migrate to the […]
Um die ökologische Nische von pelagischen Raubtieren wie Schnabelwale, Pottwale und Delfine (aber auch Seevögel, Haie, Thunfische und Schwertfische) zu entschlüsseln, muss man mehr über die Beute wissen, von der sie sich ernähren, wie z. B. pelagische Fische und Tintenfische. Dieses oft winzige ozeanische Mikronekton (mit Quallen und Garnelen) wandert nachts in die Oberflächenschichten des […]
I walk through the forest and see a few old and sturdy trees, that are dominating their surroundings. I look up and see how they sway in the wind, but they bend and hold and aren’t bothered in the slightest. Down here in their shadow, I am surrounded by an army of saplings. Most of […]
After a month at sea, we finished our last set of observations along a transect that took us back to the shelf-break. It’s been quite the journey, and the final leg marked a special turning point as the last 2 days of the cruise were heading towards Iceland and the way home. It’s been quite […]
This week we have been busy surveying the waters of Sermilik, a large glacier fjord on the east coastline and one of the few sites hereabouts that has been surveyed before. Why are we re-visiting this fjord when our other fieldsites were previously un-surveyed? Well, visiting new areas is exciting and we can perhaps find […]
