by Marie Guilpin To understand predator-prey interactions, it is essential to characterize and quantify the preyscape available to predators. One way to do so is to use hydroacoustic data. Essentially echosounders are active acoustic devices pinging at different frequencies, the echoes back from whichever is in the water column is then recorded. We used dual […]
Echosounder
von Marie Guilpin Um die Wechselwirkungen zwischen Räubern und Beutetieren zu verstehen, muss die Beutelandschaft, die den Räubern zur Verfügung steht, charakterisiert und quantifiziert werden. Eine Möglichkeit, dies zu tun, ist die Verwendung hydroakustischer Daten. Echolote sind im Wesentlichen aktive akustische Geräte, die auf verschiedenen Frequenzen schwingen und deren Echos in der Wassersäule aufgezeichnet werden. […]
“Balloon” Houses in the deep
There are many creatures suspended in the ocean that build elaborative feeding houses that have a special mission in carbon pump. One spectacular example are Appendicularians – pelagic tunicates known also as Larvaceans. As mucus net feeders, they build huge and really beautiful ‘houses’ around their bodies that comprise two layers of filters. By beating […]
Making the most of good (and bad) weather
As scientists onboard we all have a schedule for what we would like to achieve at sea. Much of this work has been planned for years with months of preparation and training. Arctic field work in this region is challenging due to poor weather and ice conditions for much of the year, so there are […]
A glimpse into the future of ocean exploration, inspired by the technology used on the RV Meteor M202 oceanographic expedition
For a marine biologist like me, it’s always a pleasure to take part in a multidisciplinary scientific campaign like M202 on a modern oceanographic vessel like the RV Meteor. In addition to the excitement of exploring the unknown that such a mission provides, the contact with researchers from different backgrounds and interests allows us to […]
Ein Blick in die Zukunft der Meeresforschung
Für einen Meeresbiologen wie mich ist es immer eine Freude, an einer multidisziplinären wissenschaftlichen Kampagne wie M202 auf einem modernen ozeanografischen Schiff wie der FS Meteor teilzunehmen. Neben dem Reiz, das Unbekannte zu erforschen, den solch eine Reise mit sich bringt, können wir von teilnehmenden ForscherInnen mit unterschiedlichen Hintergründen und Interessen lernen, neue wissenschaftliche Horizonte […]
FYORD Travel Grant Reports: Master’s students travelling to international conferences
Visiting an international conference as a Master’s student In July, the International Conference on Seafloor Landforms, Processes and Evolution (ICSLPE) was held for the second time. This year it took place on the beautiful island of Lipari. My name is Luisa Rollwage and I am a Master’s student of geophysics at Kiel University. During my […]
The beauty of plankton
by Eleonora Puccinelli You’ll find some of the smallest things on earth living in the ocean from the surface to the seafloor. Despite their teeny tiny size, these organisms are the ones literally getting the ball rolling. We call them plankton, and we can separate them into phytoplankton and zooplankton. Phytoplankton are microscopic plant-like organisms, […]
Die schöne Welt des Planktons
von Eleonora Puccinelli Im Ozean, von der Oberfläche bis zum Meeresboden, leben einige der kleinsten Lebewesen der Erde. Trotz ihrer winzigen Größe sind diese Organismen diejenigen, die buchstäblich den Ball ins Rollen bringen. Wir nennen sie Plankton, und wir unterteilen sie in Phytoplankton und Zooplankton unterteilen. Phytoplankton sind mikroskopisch kleine pflanzenähnliche Organismen, die man sich […]
eDNA Team
If you ever had sleepless nights, wondering what were the most important samples taken during this METEOR cruise, don’t dispair – we got you! The simple answer is: eDNA water samples! Okay, we admit it, we might be a bit biased as we are part of the eDNA sampling team; most likely the answer will […]
