Controlled Parameters
Research Topics

Advanced general understanding in ecology by using modularized experiments across SITES-AquaNet stations (Sweden) or potential collaborators (Sweden, Europe and other continents). Topics: Forest stand development, plant physiology, systemic water transport, forest management strategies, nutrient limitation, biodiversity-functioning-stability relationships, community ecology, biogeochemistry, atmospheric flux, global change research. On-site climate data, incl. temperature profile measurements. Possibility to combine experimental research with historical lake monitoring data from Lake Bolmen (e.g., phytoplankton, zooplankton, fish, temperature measurements and others).

Description

Description of the infrastructure: SITES AquaNet is a standardised infrastructure for national and international researchers to run mesocosm experiments in lakes that are associated to 5 field stations that are part of the SITES (Swedish Infrastructure for Ecosystem Sciences). The infrastructure is located in four SITES stations (Svartberget, Erken, Skogaryd and Asa) and in one associated station at lake Bolmen, which is operated by Swedish Water Research. Hence, SITES AquaNET enables modularised experimental manipulations in lakes that vary in local environmental conditions along a latitudinal gradient in Sweden. Each site is equipped with a jetfloat raft system deployed in its local lake with 16-20 polyethylene cylindrical enclosures (700 L, 1.5 m deep, 0.8 m Ø). The experimental facilities have sensor and data logging systems in each mesocosm for real-time measurements of environmental parameters, such as oxygen, temperature, photosynthetic active radiation (PAR), chlorophyll, phycocyanin and turbidity. In addition, handheld sensor units offer the possibility to measure in situ pH and conductivity. SITES AquaNet has established protocols to standardise both field and laboratory work. Each station is equipped with field equipment for collection of samples and there is access to cold storage, freezing rooms and laboratory facilities for filtering and extraction of samples for a wide range of analyses. The versatility of the experimental facility enables users to address questions in many different topics: biodiversity-functioning-stability relationships, community ecology, ecological stoichiometry, food web interactions, benthic-pelagic dynamics, biogeochemistry (e.g., nutrient cycling), land-water- air gas exchange, cyanobacterial blooms and global change research.

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.

What is available and when
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).

Accommodation

Lodging at or close to the stations will also be provided.
