Project Abstract

Macroalgal blooms are a widespread ecological phenomenon in which algal species such as members of the green algal genus Ulva, brown ectocarpoid algae or other algal species can proliferate in freshwater, estuarine and coastal systems. These seaweeds can thrive to such an extent that they become a social and environmental problem in the form of persistent blooms, forming dense mats or drifts. Growth and accumulation of such blooms may result in anoxic decomposition and release of gaseous sulphur compounds (e.g. hydrogen sulphide, carbon disulphide, methyl sulphide), particularly in large casts. Exposure to these noxious gases can lead to health risks in both humans and wildlife. Environmental impacts of the development and degradation of algal blooms include impacts on local biogeochemistry and biodiversity. This project aims to develop and implement analytical methods for the better understanding of the local environmental conditions that result in the development of opportunistic macroalgal blooms. Furthermore, Sea-Mat will determine the physicochemical and eco-physiological characteristics and the temporal and spatial variations in environmental conditions that potentially influence the development, abundance and species composition of these blooms. The results will inform water management decisions to control blooms in coastal bays and estuaries. This project (Sea-Mat) has the potential to accelerate the development of methods for the better understanding of the local environmental conditions that result in the development of opportunistic macroalgal blooms, as well as the temporal and spatial variations in environmental conditions that influence their development, abundance and species composition. The deliverables of this project will include a final report that will inform and guide policy makers regarding management decisions to control opportunistic macroalgal blooms in coastal bays and estuaries. The generation of four international peer-review publications will increase our international capacity and reputation in coastal environmental monitoring. Sea-Mat will provide a strong basis for a range of dissemination and outreach activities to be delivered via website and social media platforms, school activities and presentations at significant outreach events (e.g. Annual Galway Science and Technology Festival). This study will address the societal needs for environmental monitoring of opportunistic macroalgal blooms and information services, notably in the context of informing environmental legislation and policy, e.g. delivering our green potential ( as per policy document Department of Jobs, Innovation and Enterprise, 2012), including the value of ecosystem services and biodiversity to the economy.
