The STREAM (Sensor Technologies for Remote Environmental Aquatic Monitoring) project will bring together partners on both sides of the Irish Sea to better understand the impact of climate change; lower the cost of marine observation and accelerate the process of data provision. STREAM will develop sensors capable of providing real-time environmental data through web portals, mobile applications and mass-produced sensors for organisations responsible for protecting and improving Welsh and Irish waters. Data collected will be shared locally to keep coastal communities informed about the local impacts of climate change.
