Station 1:
Punta del Hidalgo. Rocky shore with a wide terrace plenty of pools of different sizes (from ±0.5 to over ±30 m2and depths ranging between ±10 cm and ±3 m). Some village settlements and banana plantations are closer to this site and marine current system should imply risky pollution (petroleum crude and distilled products from north-east area). Marine dynamics (currents, tides and waves) should be important along all seasons (autumn and winter all over).
