Deploying the sediment corer at Boknis Eck to study organic carbon burial for the @bfn-de.bsky.social ROVKA project

Including close ups of aliens from inner space…

My favorite sequence of our just completed #bioc102 class at #Geomar: pedicellariae in betweeb sea urchin spines cleaning all surfaces. Inspiration galore for sci fi #Marinelife

In between, unicellular ciliates in green tubes catch even smaller prey #bioc102

Zooming into the wilderness on the shell margin: colonies of bryozoans capturing plankton with their tentacles #bioc102 #Geomar

You can see the gill much better in very young mussels (1 mm) with transparent shells, gill filaments form the sieve and the hairs (cilia) attached to them create the water flow - several liters per hour in fully grown mussels. Mussels have a foot that they can use to reach good spots #MarineLife

Compiling some videos for our upcoming #bioc102 class with MSc Biological Oceanography students at Kiel University and #Geomar. Critter of the week: blue mussels with forests of small creatures living on their shells. We‘ll zoom into these forests in the next weeks… 🦑

Good fun with our 1st sem MSc Biological Oceanography students sampling muddy Kiel Bight sediments using grabs and corers last week with Mirjam Perner and Renate Schütt! Thanks to Crew of RV Alkor for excellent support. #Geomar #smellyscience
