10,000 miles on #Polarstern: from Namibia across the Weddell Sea to the Falklands 🇦🇶

We deployed autonomous samplers and filtered 2,000L of seawater to study microbial seasonality and ecology, in a team of 100 lovely people.

🚨Our book is now available for pre-order🚨

It was such an honour to contribute to this, as this was the book that opened my eyes to, and inspired me to study #marine #microbiology!

Highly recommend for students/academics wishing to learn about marine microbes.

I just wanted to send a quick update and thank the 70+ people who applied for the upcoming #anvio workshop and ECR symposium in Oldenburg so far.

We are very encouraged with the geographical diversity, which has been one of our main concerns. The applications are open until January 10.
