Acquisition de données sur l'expansion de Caulerpa taxifolia et Caulerpa racemosa en rade d'Hyères et en rade de Toulon (France)

The oceanographic cruise Califa 2000, as the previous cruise, which concerned the “Parc National de Port-Cros”, had for its principal objective to furnish some elements susceptible to help in the control of Caulerpa taxifolia expansion and in the protection of particularly sensitive areas (national parks, patrimonial sectors, regions of socio-economic importance). The cruise lasted from the 4th to the 21st of September 2000 in the rade d'Hyères, Porquerolles island included, and the rade of Toulon. This detailed prospection gives a location of C. taxifolia and C. racemosa, a new invasive seaweed.
