Askö laboratory

The Askö laboratory is located on the island and nature reserve Askö in the Trosa archipelago south of Stockholm. The field station is a national infrastructure resource open for anyone who wants to conduct research, environmental monitoring, arrange courses or host research meetings and workshops related to the sea. The Askö laboratory is part of the network European Marine Biological Resource Centre (EMBRC) and offers access to laboratory, research vessels and equipment.

At Askö, we have a team of five staff members who work weekdays on the island between 08:30-16:00. High-season for resarch and courses is between May and September, but there is activity during the entire year, not least within the national and regional environmental monitoring programs. The station accomodates about 40 guests and there are two well-equipped kitchens for self-service.

The Askö laboratory is home port for our research vessel R/V Electra af Askö.

Research and environmental monitoring

The knowledge about life below the surface is still almost rudimentary for the sea, compared to what we know about terrestrial environments. Researchers with with a wide range of projects come to the Askö Laboratory. Many work to improve our basic knowledge of ecology in different habitats. Others work to demonstrate the effect of different types of human disturbance on different species and ecosystems. About a third of our Askö visitors are researchers, the rest comprise course students or meeting members.

At the Askö Laboratory, researchers are offered several opportunities to study the sea, directly in field, inside the laboratory or in the middle, in the mesocosm experiment hall. Different methods suit different types of research.

Meetings and workshops

With its idyllic environment, Askö is in many ways an ideal place for creative meetings. The isolated location and the beautiful surroundings provide good opportunities to focus, exchange experiences and drive processes forward within a project.

At the station, everything needed for effective meetings is available, an environment that makes it easy to team-build and the opportunity for exciting activities. Maybe try the snorkeling trail during the break? Or take a bike ride to the most beautiful beach in the entire archipelago? Barbeque in the evening sun and have a sauna session in the moonlight! Feel free to contact us for advice and inspiration before your meeting!

Courses and education

Many different courses use the Askö Laboratory annually to let the students try out field work in practice. The majority are university students from undergraduate level programs to highly specialized doctoral courses.

Approximately 400 students spend shorter or longer time at the Askö Laboratory. In total, we host 20 different courses on the island yearly.

The laboratory is well-equipped for research and teaching, both in the field and indoors. Of course, we also have excellent facilities to hold different types of meetings.

For instance, the station offers running brackish water directly from the sea, climate room, experimental hall, multi-purpose laboratories, conference rooms and wireless internet. Of course we also have plenty of field equipment for sampling, our own diving room and complete snorkeling gear.

The nature on Askö is very beautiful, and there are plenty of berries, mushrooms and wonderful swimming sites with both rocky and sandy beaches. There is also a nice little sauna right by station.

There is no shop on Askö, most guests bring food that they prepare in one of our kitchens. It is also possible to order catering for your group, let our staff know if that is a request.

On the island, about 40 people can sleep in dormitories or cottages. Courses usually live in the "course corridor" where you share a room, and research groups usually live in our small houses. Get in touch if you want to know what suits you best! Always bring your own bed linen (sleeping bags are not allowed!) and slippers.
