Years of Mesocosm Experiments
2009 to present
Description of Facility

outdoor – pelagic/benthic – marin

12 polyethylene mesocosm-bags up to 5 m3 (1.32 m diameter) incubated in two large volume concrete tanks (one with volume 150 m³ and 3 m depth and a second one with volume 350 m³ and 5 m depth)

9 benthocosms combining water column (1.5 m3, 4 m deep, 0.64 m diameter) and sediment (85 L) in the same polyethylene mesocosm-bag

The smaller (150 m³) tank is equipped by a sophisticated, fully-automated heating/cooling water system with electric valves, resistances and temperature sensors that allow water heating/cooling and temperature control at ±0.5 ºC of targeted temperature

Controlled Parameters

Temperature, light, nutrients

Research Topics

Response of the ultra-oligotrophic food web of the Eastern Mediterranean to perturbations, climate change scenarios (simultaneous effect of warming & acidification), impact of aerosol input, effect of silver nanoparticles, benthic-pelagic coupling at benthocosms, hypoxia
