Case Studies


The Irish Atlantic Case Study is focused on shellfish aquaculture and associated industries and, the effect of climate change on harmful algal blooms (HABs), caused by biotoxin producing microalgae. In Ireland, the shellfish industry provides crucial employment and supports the livelihood of many local communities. A high number of businesses are located in the southwest coast, which is our main target area in this case study. READ MORE.



The French Atlantic Case Study is focused on the consequences of harmful algal blooms (HABs) such as Dinohysis and Alexandrium on shellfish aquaculture. READ MORE.




The Baltic Sea is a semi-enclosed regional sea in northern Europe with relatively low-saline water due to excess fresh water runoff and a narrow and shallow entrance from the North Sea. Irregular saline inflows cause a salinity stratification that prevents wind mixing and fall convection from ventilating the deepest layers. This unlucky natural design combined with many years of eutrophication has caused a situation with anoxic and hypoxic conditions in the deeper parts of the Baltic Sea and an excess of available phosphorous in the system.

Chemical pollution and severe eutrophication are important environmental problems on the northwestern shelf of the Black Sea. High biomass microalgal blooms (leading to low oxygen levels in the water column and sediments) and microbial pathogens threaten aquaculture and tourism activities. READ MORE



The participants at ICM-CSIC and IAEA-CSIC are studying the dynamics of Ostreopsis blooms in the NW Mediterranean, Catalan coast. In particular, their research is focused on a hot spot were recurrent events occur every summer and are associated to mild respiratory disorders in beach users, workers and inhabitants in the area. We are characterizing the ecology of the blooms, the chemical composition of some Ostreopsis metabolites and conducting epidemiology studies on the affected human population. READ MORE.


The study encompasses climate change effects on harmful algae in the North Sea area including the Kattegat and the Skagerrak. The goal is to develop climate services in this context. Stakeholders and end users include the aquaculture industry and coastal zone managers. READ MORE.
