     The `marphy' data frame has 68 rows (stations) and 4 columns. They
     are seawater measurements at a deep of 3 to 7 m at the same 68
     stations as `marbio'.

     This dataset corresponds to a single transect sampled 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 measurements where
     recorded. They correspond to the stations where zooplankton was
     collected in the `marbio' dataset. Water masses in the transect
     across the front where identified as:
