- Open access to national and international researchers.
- Outdoor, freshwater, lake deployed in an adaptable jetfloat.
- PE-film enclosures or 20 hard-shell PE enclosures (ø = 0.9m, depth = 1.5m, volume = 700L).
- In addition, there is access to another set of 20 hard-shell PE enclosures (ø = 1m, depth = 2 m, volume = 1200L).
Advance general understanding in ecology by using modularized experiments across SITES-AquaNet stations (Sweden) or potential collaborators (Sweden, Europe and other continents). Topics: biodiversity-functioning-stability relationships, community ecology, ecological stoichiometry, food web interactions, benthic-pelagic dynamics, biochemistry (carbon cycling), cyanobacterial blooms and global change research. Possibility to combine mechanistic experiments with historical (decadal) lake monitoring data from Lake Erken (e.g., phytoplankton, zooplankton, fish, nutrients and high frequency temperature measurements).
Apogee SQ-500 (PAR), CTG Trilux fluorometer (chlorophyll-a, phycocyanin and turbidity) and Aanderaa 4531 optode (O2 and temperature) sensors fulltime deployed in each enclosure. CR1000 dataloggers and AM16/32B multiplexers. Possibility to develop Internet interface for collected data. One EXO2 Multiprobe (https://www.ysi.com/EXO2) one AP-2000 AquaRead Multiprobe (http://www.aquaread.com/portofolio/ap-2000/) and one Apogee MQ-500 (PAR) with handheld meters. Laboratory analytical services available in site (http://www.ieg.uu.se/erken-laboratory/analytical-services/) or at Uppsala University (http://www.ieg.uu.se/limnology/)
Capacity in site (Erken Laboratory) up to 60 people with fridges, freezers and cooking facilities (http://www.ieg.uu.se/erken-laboratory/.)
