EU network of mesocosms facilities for research on marine and freshwater ecosystems open for global collaboration.

SITES AquaNet – Bolmen Forskningsstation


The mesocosm facility does not open for Transnational Access (TA) in 2021.

For new TA opportunities please go to AQUACOSM-plus.

Years of Mesocosm Experiments
2017 - present
Description of Facility
  • Open access to national and international researchers.
  • Outdoor, freshwater, lake deployed in an adaptable jetfloat.
  • PE-film enclosures or 20 hardshell PE enclosures (ø = 0.9m, depth = 1.5m, volume = 700L).
Controlled Parameters
Research Topics

Advance general understanding in ecology. Topics: biodiversity-functioning-stability relationships, community ecology, food web interactions and benthic-pelagic dynamics. Possibility to combine experimental research with historical lake monitoring data from Lake Bolmen (e.g., phytoplankton, zooplankton, fish, temperature measurements and others).

Modality of access

Modality of access under AQUACOSM-plus: A total of 1600 person-days will be allocated to external users supported by an AQUACOSM-plus TA activity in year 3. At least 1600 person-days will be allocated to external users of AQUACOSM-plus TA provision. It is anticipated that AQUACOSM-plus will support a minimum of 5-6 persons for 57-60 days per year in M22-33. A typical experiment is expected to run for 6-8 weeks (excluding preparations). TA access is however recommended for longer stays for 3-5 users per station. The primary objective for access will be the implementation a coordinated experiment in all 5 lakes that addresses a grand scientific challenge as defined in Task 6.1. TA users will have the opportunity to be part of this synchronised experiment, which includes planning, on-site preparation, and implementation of experiments at the different field stations. One of the nodes (the Erken Laboratory) can also host participants during the sample analysis period after the experiment and can offer access to laboratories, instrumentation and the scientific environment at the Department of Ecology and Genetics at Uppsala University as well. The access costs are estimated based on real cost calculations.

Unit of access


What service and support facilities are available

Services currently offered by the infrastructure: External users have open access to equipment to run mesocosm experiments in one or more lakes spread across a geographical and climatic gradient in Sweden. This includes sensor calibrations and installations, support with installing and uninstalling of mesocosms, online-visualisation of sensor data, access to sensor data and lab space, equipment for sampling and sample preparation and sampling protocols. Data from lake and time series data is also available through SITES Water (coordinated by Skogaryd and Svartberget) comprising a multi-layered lake and stream monitoring program including hydrological, physical, chemical and biological parameters as well as GHG and C fluxes. Additional technical and analytical support by experienced staff is available when costs are covered, including the possibility for water analyses in accredited laboratories. The infrastructure was established in 2017 and has so far been used for experiments that manipulated fish predation, light, salinisation and browning. In addition, one station (Erken Laboratory) can also provide 20 1500 L polyethylene enclosures. Activities at the different stations include a large variety of long-term monitoring programs and research projects within the field of ecosystem science, which gives users the possibility to interact with technical staff and researchers working at the stations.

Support offered under AQUACOSM-plus: TA users will have full access to the mesocosm infrastructure and services described above, as well as training by technical staff in sampling procedures and use of equipment and instruments. Standard disposables as well as administrative and logistic support (cars and boats).


Capacity in site (Bolmen Forskningsstation) up to 5-6 people with general facilities needed for accommodation.
