Da a conocer las condiciones hidrológicas, características hidroquímicas, distribución del estado biológico de los peces frente a la costa y estudia las corrientes en las aguas peruanas durante la primavera de 1972.

Cuarto crucero del barco de exploración científica Profesor Mesiatsev (VNIRO). 12 de diciembre 1972 - 8 enero 1973. Informe sobre los trabajos científico-pesqueros en las aguas adyacentes a la costa del Perú

Informa sobre los resultados de los trabajos conjuntos del VNIRO (URSS) e IMARPE (Perú) como parte de un convenio de cooperación técnica Peruano-Soviético, que tuvo por finalidad estudiar los recursos pesqueros del litoral peruano.

Condiciones hidroquímicas frente a la costa norte-centro del Perú durante agosto-setiembre 2001

Estudio de la superficie del mar, el oxígeno disuelto y los nutrientes presentaron valores propios de las Aguas Costeras Frias (ACF). Se hallaron dos áreas más frías, relacionadas con los procesos de afloramiento, una desde Punta Falsa hasta el norte del Callao y la otra al Sur de Cerro Azul hasta Pisco, hambas con concentraciones de oxígeno <4mL/L y valores altos de nutrientes.

Aportació al coneixement de la dinàmica fluvial en la conca del riu Onyar (Girona)

Two decay rates are distinguished in the discharge hydrograph of the Onyar River, using Maillet's formula. In this way, we can know which Kina of influence is made by geomorphology and rainfall distribution on fluvial processes

Anàlisi geomètrica del Diaclasat de les Guilleries en el sector de la Vall del Ter entre els embassaments del Pasteral i Susqueda (Girona)

The Guilleries are a small and mountainous area located in the north-westem part of the Catalonian Coastal Ranges where metamorphic and igneous Paleozoic rocks are exposed. After the main hercynian folding this area was affected by a brittle deformation that is mainly manifested by the intrusion of a very large number of dykes of granodiorite and the development of a complex joint system. Trends of dykes indicate that their intrusion was related to a SE-NW extension, whose estimated value is 40% on an average. This extension seems to stand, although without any associated igneous event, with the development of NE-SW directed joints which make the main set. Five families more were developed later, onegently-dipping and fou upright; the latter trending roughly SE-NW, ENE-WSW, ESE-WNW and N-S. AU the joint sets appear in the metasedimentary Paleozoic rocks and in the hercynian intrusive bodies. Concerning the ages, joints that belong to the NE-SW and SE-NW directed sets and also those slightly dipping have been attributed to the late-hercynian times and all the other are considered to be later

Característiques geomorfològiques de la Pedralta (Baix Empordà, Girona)

Descripció de les característiques geomorfològiques de La Pedralta, entre els municipis de Santa Cristina d'Aro i de Sant Feliu de Guíxols

Aportaciones al conocimiento de la geología de Bac Grillera (prepirineo, Girona)

The Bac Grillera nappe (Prepirenean of Girona) shows a stratigraphic section composed of two unconformi ty-bounded units. The lower unit is composed by rethian (marly limestones) and liassic (brechoid marly limestones and limestones). The upper unit (sandstones and marly limestones) belongs to the upper Cretaceous (Campanian)

Las formas graníticas de los macizos de les Gavarres i de Begur (Girona)

In the present paper the granite landforms of the Les Gavarres and Begur massifs (Girona) are described. Also the relationship between this landforms and the lithology are analysed

The geophysical electromagnetic prospecting in the spatial location of the travertine deposits of the Banyoles Depression (Girona)

The results of the application of the geophysical electromagnetic prospection methods in the resolution of the problems of the spatial location of the travertine quaternary formations of the Banyoles depression are presented

La Pedralta, un ejemplo de patrimonio geológico de Girona

Pedralta is a very large rocking stone shaped in monzonitic granite. Its volume and weight are approximately 34 m3 and 90 Tm. The fall of such block has supposed the loss of a worthy geotipe

Aportaciones al conocimiento del Cretácico del macizo del Montgrí (Girona)

ln this paper we describe a stratigraphic column of the Cretaceous of the Montgrí. This description is based on several partial stratigraphic cross sections as well as on the lithological characterof the different levels and their faunal content, specially megafossils

Morfolitología de las terrazas del Ter en Girona

It is a contribution to the study of the terraces of the river Ter along its mid-course in the town of Girona, since that is the last speace where it is still possible to observe four of these terraces with clear characteristics of climatical deposition. Itsmorphological peculiarities are described as well as the morphometrical and lithological parameters of its pebbles. These terraces are compared with others which have been studied in other areas of the regions and conclusions are drawn concerning deposition, source àrea and chronology

Presencia del paleogeno bajo los sedimentos neogénicos de Vilablareix (Girona)

This study makes clear the existence of a paleogenical red basal level (Pontils Fm.) in the Vilablareix àrea, under the mio-pliocenical cover of the Girona plain, enlargening the surface known go far of that level
