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

First cruise with our new M.Sc. students in Biological Oceanography @geomarkiel.bsky.social @uni-kiel.de to sample sediment cores for organic carbon & DNA, image ammunition dumpsites and investigate macrofauna! Thanks to Jens Greinert, Mirjam Perner and teams - and the excellent crew of RV Alkor

2 years of data in one of the most extreme Fucus habitats in the Baltic - locating stones with loggers always is a challenge.

And: with our new drawing booklet designed by the very talented @katjasee.bsky.social and Alexandra Hahn @geomarkiel.bsky.social

Busy week Fucus sampling with our colleagues @gloriareithmaier.bsky.social @lies-nerd.bsky.social @karikaphegyi.bsky.social and lots of others for #Fubluc and getting ready for outreach with kids for #TheOceanRaceEurope @geomarkiel.bsky.social

Doctoral position on genomic basis of Fucus (brown algal) local adaptation - join our exciting #Fubluc team! Fully funded for 3.5 years & we also consider candidates with strong molecular or bioinformatic skillls but no marine / algal experience, see www.geomar.de/en/karriere/...

Including close ups of aliens from inner space…

Still 5 hours left to meet us and various marine critters on board if RV Alkor & the Kiel Outdoor Benthocosms with an experiment on carbon storage potential of brown algae with @lies-nerd.bsky.social @geomarkiel.bsky.social #FUBLUC - and the sun is out now!

Finally some practical #bioc-202 work for our MSc students in Biological Oceanography at #Geomar! Exposing bladderwrack populations to heat stress regimes to study photophysiology & local adaptation! Real science projects to support meadow conservation #ANK #FUBLUC with @lies-nerd.bsky.social

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
