The Sargassum APP lets you record the amount of seaweed which washes up on beaches. You report on the seaweed mat's coverage on the beach as well as its thickness. You can also take a photo if you wish. When you upload the information your coordinates are provided and scientists can use the information to document changes over time. Recent reports are shown on a map. You can use this information to help plan your beach day but remember, many communities clear their beaches daily.
