Microplankton and Metazooplankton from the Catalan Coast, December 15th, 2022

In these 3 videos you will find a summary of the most relevant findings from PUDEM sampling in front Barcelona. The community was rather surprising, because it seemed an end of summer one, with cladocera (Penilia avirostris and Evadne spp.) and Oithona spp. combined with a diatom bloom of very large and diverse species. I guess this community reflects the unusually warm temperatures we had this year.

I highlight the presence of the pennate diatom Bacillaria paxillifer that forms colonies in which adjacent cells glide using filamentous structures.
