Spain: location
Spain: seas and oceans
Mediterranean Sea: warmer than the others
Cantabric Sea
Atlantic Ocean
The mediterranean coasts: Mild temperatures Irregular rainfall
Spain: different climates
Inland : the climate is more extreme• Low temperatures in Winter and high in Summer• Irregular rainfall

Summer• Abundant rainfall
Situated in Northwestern Spain Area of 29,574 km² 1500 km of coast Four provinces: three of them are in the sea shore. Oceanic climate: Winters and Summers are mild with abundant rainfall
Galicia: our region
Ocean/Seas. Most important. They condition the climate
Rivers Lakes (fresh water) and lagoons (salt
water) Subterranean waters
Galicia’s bodies of water: types
The most important geographical feature of our coast
Inlet that advances into the ocean They coincide with the mouth of a river They are subject to the tides
Rias (estuaries)
Rivers that flow into the rias
Rias
Northern Rias: Ferrol, Coruña…
Southern Rias: Arousa, Pontevedra…
They are different in the height of the coast and in their size
They are very productive due to the rise of cold waters coming from Atlantic currents
Rias
Rias of Coruña, Betanzos and Ferrol
TIDES
The average tide is approximately 2.7 metersToday (March 15th) High tide: 1 m Low tide: 1,1 m
Ria of Ferrol: data
Average salt in sea: 34- 35,6/1000 g salt/kg water
Mix of fresh water and sea salt water.
Salinity suffers variations in Winter due to continental water.
This influence is much smaller at depths over 20 meters
Surface water temperature Minimum of 10-12 ºC in Winter Maximum of 18-20 ºC in Summer
