     This dataset corresponds to a single transect sampled with a
     plankton net across the Ligurian Sea front in the Mediterranean
     Sea, between Nice (France) and Calvi (Corsica). The transect
     extends from the Cap Ferrat (close to Nice) to about 65 km
     offshore in the direction of Calvi (along a bearing of 123). 68
     regularly spaced samples where collected on this transect. For
     more information about the water masses and their physico-chemical
     characteristics, see the marphy dataset.
