Details
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.
