| Summary: | 27 páginas, 24 figuras, 3 cuadros [EN] On the basis of data provided by the cruises «Galicia I, II, III and IV», water bodies off the Galician coast [Northwest of Spain) from a depth of 1500 m to the surface are described herein in the period from June to October. The Mediterranean Water vein (MW) is very clear in the western coast at the level of 1200 m. A proportion ol 77% MW is still found at this area, though it decreases at the northern coast of Galicia. Its distribution is similar to the one previously described by other authors. Central Water is located between 75 m and 400 m. It presents two clearly different bodies: while in the western cuast the North Atlantic Central Water (NACW) is found, highly modified Central Water is observed in the northern coast. Its upper part is homogeneous with salinity values between 35,56 and 35.58 %o and temperature values between 11.0 antl 11,6ºC. The most representative T-S diagrams are those corresponding to stations 16-III and 56-III in figure 8. The water off the northern coast is supposed to have its origin in the Celtic Sea, but the water off the western coast of Galicia is thought to come from a latitude inferior than 40ºN. A circulation for these two water bodies is proprised as it is shown in figure 3. The very clear boundary between them is indicated by the dotted zone. The variations of surface water characteristics are due to meteorological conditions. Temperature decreases against the coast as an effect of the upwelling of Central Water. This effect is specially important in the northern zone of Cape Finisterre and can be explained by the intensification of the upwelling in that zone. Surface cirulation also varies. In this months it borders the coast prcedominantly from the northest to the south [ES] Se describen los cuerpos de agua de la costa de Galicia (NO de España) desde la superficie hasta una profundidad de 1500 m, durante los meses de verano, de junio a octubre, utilizando los datos de las campañas oceanográficas "Galicia I, II, III y IV".
