Outdoor – pelagic/benthic - freshwater
32 cylindrical insulated fibreglass outdoor mesocosms, each 1.0 m deep and 2.0 m in diameter (3000 L) arranged in four rows with eight mesocosms in each and 3 fibreglass tanks 1.0 m deep and 4.0 m in diameter (12000 L). The site was built in 2011 and is located around 2 miles from the CEH office.
We have 99 flat bottomed and 100 unique sloped mesocosms which are designed to simulate edge of field environments. Our sloped mesocosms were installed in 2013, are 2.6 m long, 1 m wide and 0.7 m deep and are used for herbicide studies. The sloped mesocosms are designed to enable the incorporation of a wide variety of plant species, providing a habitat which mimics the plant community found in edge of field environments. Our flat bottomed mesocosms were installed in 2009, are 1.8 m long, 0.9 m wide and 0.8 m deep and are predominantly used in pesticide studies.
96 freshwater mesocosms, 32 more coming in 2017
