The beginning of 10 intense days

It’s August 1, 2018 and there are a lot of enthusiastic students in the normally quiet Tjärnö. The reason for their excitement is the beginning of the Joint School. For ten days they will work together in groups at the Sven Lovén Centre for Marine Infrastructure to conduct a small research project. Of course, they are also very excited to see each other again after one month of separation.

As the day passes by, it gets more and more active on the island. And soon the little groups start to chat about a possible research topic. There is a welcome presentation and a nice first dinner, and after, the groups start brainstorming. This blog will follow a particular group of students. Our group consists of six students that want to dedicate these ten days to rocky shores, and more importantly what lives on these shores. That’s why we call ourselves ‘The Rockers’. As it gets darker and some are seeking for b e e r, our plan starts to form.

The second day is a whole day dedicated to writing the proposal of the project. There are some discussions and some good advice from our very helpful supervisor, Gauthier. Finally at four o’clock our proposal is ready, with the title: ‘Biotic and abiotic factors affecting community composition of the rocky shores of Saltӧ’. For abiotic factors we will go in the field and do a survey of two types of rocky shores: exposed rocky shores, located on the West side of the island and exposed to wind and waves, and sheltered rocky shores, located on the East side. Wave action, substrate type and depth are the abiotic factors of our main interest. A lab experiment including crabs (Carcinus maenas) and snails (Littorina saxatilis) will be conducted to look at biotic factors such as the influence of predation on habitat choice.

Besides this experiment we as The Rockers will carry out, we will also explore the beautiful surroundings and enjoy ourselves. Therefore, the third day started with a refreshing dip in the salty water in front of the research centre before breakfast.

IMBRSea Summer School embarks in Tjärnö

The International Master of Science in Marine Biological Resources (IMBRSea - www.imbrsea.eu ), this year organizes the first summer schools at the Tjärnö Marine Laboratory in Sweden. From 1 till 11 August 39 students and 10 teachers are working on seven challenging research projects. Follow the adventures of the seven research teams in the coming weeks via this blog!

Sampling Tjärnö Bay

Professor Karim and Lucy after our last deployment, hurray!! Our experiments are finally finished! We were able to deploy BRUV (see our Finding Fish in Tjärnö Bay post for a description :) ) at all of our sampling locations, plus a few bonus ones. We sampled three different habitat types: sandy, muddy/algae, and harbour areas. Map of Tjärnö Bay with our sampling locations At all of our habitats we sampled at a depth of approximately 1.5 meters to assess what animals are typically found in the littoral zone of Tjärnö Bay - the littoral zone is the region of the sea closest to the shoreline. On our final day of sampling we decided to do a few extra deployments at 10 meters to search for species we didn’t find at shallower depths. We’re working on analyzing all our video footage now - stay tuned for an upcoming creature feature post!

Goodbye my BRUVver, Goodbye my friend

Just a few hours are left of the summer school, the report is done, presentation complete, video shown (to mixed reviews…philistines). We’ve had an incredible time here in Sweden and have learned a lot, about fish, BRUV devices, and ourselves… One of the many beautiful sunsets of Tjärnö Surprisingly our experiments worked out well, we discovered that the most complex habitats did indeed have the most fish. They like structures and hiding places, but not as much as they like mussels…which is why we managed to actually see them on the video! We watched many clips like this screenshot to count so many fish Thank you for keeping up with Team eFISHency over the past 10 days! We’ve enjoyed every moment (well mostly…), and are really happy with our work! xoxo Gossip Pearl
