Researchers and students involved in the Vent and Seep Fauna project recently presented our work at the Science by the Sea event organized by the Centre for Deep Sea Research at the University of Bergen. The event was a full day seminar with presentations by researchers from the centre on a broad range of topics including geology, geochemistry, microbiology and biology, followed by a poster session where students could present their work.
We currently have three students involved in the Vent & Seep Fauna project, two master students and one PhD student. Tomine is writing her master thesis on the fauna of the Jan Mayen vent fields. Based on new material collected in 2021 she will make a taxonomically updated species inventory for the vent fields and assess if the previous conclusion that these relatively shallow vent fields have very little specialized fauna still holds true. Amalie is writing her master thesis on the fauna of the Ægirs Kilde, and will characterize the fauna of this vent field for the first time, and compare it to other vents on the Arctic Mid-Ocean Ridge.
Brendas PhD project focuses on snails in the family Rissoidae, which are very abundant in Arctic chemosynthesis-based ecosystems. Firstly, will assess the diversity, phylogenetic position, geographic distribution and habitat specificity of these snails. Then she will explore the genetic connectivity between populations using RADseq and a biophysical dispersal model, and also sequence their microbiome to understand more about their adaptations to living in chemosynthesis-based ecosystems in the deep sea.
