EU network of mesocosms facilities for research on marine and freshwater ecosystems open for global collaboration.

Nitrogen Cycling in Climate-impacted Lake Mesocosms (NCyCLMe)

Mark J. McCarthy, Shannon M. Collin, Erik Jeppesen, and Silvia E. Newell Wright State University, Department of Earth and Environmental Sciences Dayton, OH USA Cyanobacterial harmful algal blooms (cyanoHABs, also known as blue-green algae blooms) are a global problem, fouling water with surface scums and toxins. CyanoHABs are caused by excess nutrient loading (phosphorus and… Read more »

Weathering of polymeric particles in semi terrestrial environments – a mesocosm study with PVC

Unique and highly diverse properties of plastics, their easily processing and the low production costs have lead steadily increasing plastic production reaching 322 million tons worldwide in 2015. Plastics have delivered many benefits to society in various sectors; however global plastics pollution is a consequence of unsustainable use, uncontrolled and inadequate plastic disposal and waste… Read more »

TA access at the Artificial Pond and stream system of the Umweltbundesamt in 2018

Project title: Metformin Transformation in a Large Scale Artificial River System Project acronym: TransMet Project duration: May to August 2018 Metformin is one of the most commonly prescribed antidiabetic pharmaceuticals on the global scale and recent studies indicate that metformin might cause endocrine disrupting effects in fish. It enters the waste water untransformed as it… Read more »

Tracking the effects of reduced nitrogen loading

A mesocosm experiment at LMWE Silkeborg Denmark 2018 Whilst we know for certain that eutrophication in fresh waters is caused by increased nutrient levels, the relative influence of the two most important nutrients, phosphorus and nitrogen, is the subject of much debate. Recent work has asserted that eutrophication cannot be controlled by reduction in nitrogen,… Read more »
