Years of Mesocosm Experiments
2011 - present
Description of Facility

Outdoor – pelagic/benthic – freshwater

24 large lake mesocosms, each 9 m diameter, 20 m depth, reaching into the sediment, water volume 1,270 m3 per mesocosm, one additional central unit 30 m diameter, volume 14,000 m3

Controlled Parameters

e.g. thermocline depth, stratification, extreme wheather events, browning, nutrients

Research Topics

Responses of the planktonic food web, biodiversity patterns, and biogeochemical processes and fluxes under climate change scenarios

Primary interests
Specialist areas
Equipment

Each of the 24 mesocosms is equipped with:

  • an automatic profiler recordimg PAR, temperature, pH, oxygen, redox potential, conductivity, turbidity, and pigments to distinguish four major algal groups
  • an industrial computer recording and transmitting the collected data to servers at IGB
  • sediment traps
  • a height-adjustable water recirculation system with a perforated ring, rising conduit and pump
Lodging

IGB guesthouse, 20 beds, kitchen; local B&B
