The determination of the scheduling and quantity of irrigation is a research activity of great importance because of the intimate relationship between water and production. This relationship varies as a fuction of the climate and crop in question. The purpose of this study was to determine the relationship between the evapotranspiration of different crops and the evaporation of a class A tank as an integrator of climatological characteristics. For each crop under study, an analysis was made of the dependence on the environment, differences between consumption patterns, and the efficiency of evapotranspiration.

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". La vena de Agua Mediterránea (AM) es muy clara en el nivel de 1200 m en la costa oeste, en la que todavia alcanza el 77% de AM referido al agua tipo que se encuentra en este nivel y fuera del estrecho de Gibraltar. La proporción decrece en la costa norte de Galicia y su distribución es similar a la descrita anteriormente por otros autores. El Agua Central está localizada entre 75 y 400 m; a niveles inferiores está mezclada con cantidades crecientes de AM. El Agua Central en la costa de Galicia presenta dos cuerpos de agua bien diferenciados. En la costa oeste es Agua Central Nor-Atlántica (ACNA) típica, mientras que en lo costa norte es Agua Central muy modificada con una fuerte homogeneización vertical, con valores de salinidad entre 33,56 y 35,58%o y la temperatura entre 11,Oº y 11,6ºC. | Los diagramas T-S más representativos de estos dos cuerpos de agua son los de las estaciones 16-III y 56-III de la figura 8a. El cuerpo de agua de la costa norte se supone que tiene su origen en el mar Céltico durante el invierno, mientras que el de la costa oeste viene de latitudes inferiores a 40 N. En la figura 3 del texto se propone la circulación probable de estos dos cuerpos de agua entre los que hay una zona limítrofe indicada con punteado. Las características del agua superficial son variables, puesto que dependen de las condiciones meteorológicas, pero hay un decrecimiento dee Iti temperatura contra la costa debido al Agua Central aflorada, que tiene su máxima intensificación un poco al norte del cabo Finisterre. La circulación superficia1 también es variable: estos meses es predominantemente del nordeste hacia el sur, bordeando la costa. | Peer reviewed
