Years of Mesocosm Experiments
Established 1902; Large field mesocosms run periodically since 1988

Description of Facility

pelagic – marine – outdoor

A large nature reserve surrounding TZS is dedicated to research, providing access to a pristine environment for field mesocosms. Research vessels and technical services support sampling and maintenance; a hovercraft allows winter-studies. Aquarium facilities with natural or artificial light are available for flow-through experiments at up to 100 000 m3 daily water capacity. A marine laboratory provides analytical services.

Controlled Parameters

Temperature, light, pH, pCO2, nutrient levels, community composition, turbidity

Research Topics

Biodiversity, stoichiometry, benthic ecology, plankton ecology, seagrass ecology, ice studies, reproductive evolution in fishes
