Preliminary mapping of the alien seaweed Hypnea cornuta (Rhodophyta, Gigartinales) in the Mar Piccolo of Taranto (southern Italy, Mediterranean Sea)

Hypnea cornuta distribution was assessed by the high resolution multispectral satellite remote sensing technique in the Mar Piccolo of Taranto, on the basis of multi-temporal in situ data acquired during the entire growth season. Different in situ biomass values were recorded between two stations out of the four sampled in the same period. These differences allowed us to properly calibrate the remotely sensed data
