What is a Seaweed Bloom?

Ireland has a long and varied coastline that is host to approximately 500 species of seaweeds. Most of these species live in intertidal and subtidal rocky habitats, often supporting amazingly complex marine ecosystems.

Occasionally, some seaweeds experience the perfect conditions for fast growth, particularly in estuaries. Higher temperatures, light levels and concentrations of seawater nutrients can often lead to sudden high density blooms of green, red and brown seaweeds. These blooms can be of nuisance to the public and harmful to the surrounding environment.


Our Project

The MACROMAN Project aims to understand the mechanisms behind macroalgal blooms in order to develop appropriate management tools.

We take a multi-disciplinary approach to this task, combining traditional and aerial survey techniques, molecular and biochemical analyses and laboratory growth experiments to answer our questions. 


Meet The Team

Who gets the muddiest in the field? Who knows their Ulva lactuca from their Ulva rigida? Meet the MACROMAN team - a busy band of researchers and volunteers!



We believe that learning about our environment through scientific research shouldn't stay just within universities. We are developing outreach resources and social media content to communicate our results to schools and the general public.
