||Available hydrographic data for the Catalano-Balearic sea indicate the presence of a ridge-shaped elevation of the isopycnals, forming a front parallel to the Catalan coast, approximately mid-way between the Iberian peninsula and the Balearic islands. This structure appears as a divergence between the southwest-flowing coastal current on the Catalan side and a flow to the northeast on the island side, and is associated with consistent regularities in the biological distributions. Repeated studies of the mesoscale distribution of phytoplankton organisms have shown patterns that may be interpreted in relationship with the presence of the front.
