| Definition | Surface of sea and ground covered by the blade morphotype of the macroalgal genus Ulva estimated by aerial photography and GIS processing, estimated by excluding area within the bloom where the target organism was absent or not dominant. This parameter can sometimes be referred as 'Theoretical area' or 'Theoretical surface'. This kind of parameters is used in the monitoring of opportunistic macroalgal blooms such as 'green tides'. | ||
