    Description: Geoethics is born with the intent to highlight the social role of Geosciences, to encourage a critical analysis on the use of natural resources, to promote the enhancement and protection of the Geosphere, the correct information on risks, hoping the involvement of the scientific community in the idea of a common and shared “geological” heritage. But what is the deep meaning of the word “geoethics”, its origins, its use? The word derives from the combination of “geology” and “ethics”. “Geology” is simply “the study of Earth”. The etymological analysis of the word “ethics” is more complicated: it seems that at its origin there is a root of dual meaning: on the one hand it contains the sense of belonging to a community, it defines the relationship between men; on the other hand it expresses the individual, the ego in relationship to itself. It follows that ethics concerns what is common, but also what is personal, what distinguishes the individual. Ethics is both “being part” and “belonging to oneself”. In addition, a Semitic base assigns to this word the original meaning of “experience”. Thus, ethics is defined as the research of criteria that enable the individual to properly manage their freedom with respect for others, in the attempt to find the meaning of human life, understood as individual life and in relation with the Planet Earth. It is subjective when it deals with the subject acting, objective, when the action is related to common values and institutions. Consequently, we can define geoethics on the one hand as the investigation and reflection on the behaviour of men towards the Geosphere, on the other hand as the analysis of the relationship between the geologist who acts and his own action, with clear implications of responsibility both in scientific research and in professional practice. Starting from the etymology of some words related to the world of Geosciences, it will be tried to grasp the meaning of the geologist’s activity.

    Description: Monte Corchia is one of the most typical geological structure of the Alpi Apuane but this is not the only peculiar aspect of this territory. Within a very small area it is possible to combine structural geology, marble exploitation, geomorphology and ore deposits. The last point is of worth of interest because the area has been the subject of ore exploitation until the recent past. Within the marble succession of the Corchia synclinal core develops the longest Italian cave with 52 km of passages and galleries. Ongoing researches are exploring the huge paleoclimatic archives preserved within the carbonate concretion of the cave and are reconstructing, with extreme detail the climatic and environmental evolution of this sector of the Mediterranean basin.

    Description: The Holocene is the most recent geological epoch spanning from about 11700 years ago to the present day. The most important human civilizations appeared during the Holocene. From the Holocene onwards, environmental changes, and the hazards associated with them, became extremely important for their impact on historical events, in some cases blending with humanity’s vicissitudes and influencing the rise and decline of civilizations. This paper summarises the geological and climatic conditions of Northern Europe during the Holocene and tries to determine whether or not they support the hypothesis formulated by Felice Vinci (Vinci, 2003) about the migration of Baltic populations towards the Mediterranean in the Bronze Age at the end of the “climatic optimum” (Houghton et al., 1990; Rohling & De Rijk, 1999). This study presents data on glacio-eustatic changes and on isostatic uplift together with information on probable tsunamis that occurred in the North Atlantic, North Sea, Scandinavia and the Baltic Sea. Moreover, some data on catastrophic events that affected the Mediterranean region are reported, because these catastrophes could have favoured the settlement of “people coming from the sea” that took advantage of the demographic and socio-economic weakening of indigenous populations (Driessen, 2002). The paper aims to provide geological and palaeogeographic constraints to the hypotheses formulated by Felice Vinci on the migration of Scandinavians towards the Mediterranean. The data analysed have been collected from the available scientific literature (see references). The amount of information available for each geological phenomenon is vast and sometimes theories developed from the same data are in conflict. The comparison between the Mediterranean and the Baltic areas (one of which could have been the theatre of the Homeric events) will be useful to find evidence of geological phenomena within the Homeric texts, giving useful indications to better understand where the poems are set or at least to provide interesting discussion points related to Felice Vinci’s hypothesis (Vinci 2003).

    Description: A comprehensive study of the Late Neogene tectonostratigraphic development of the Crotone Basin is presented. The basin is situated on the accretionary wedge along the external side of the Calabrian Arc (Central Mediterranean). The results of our analysis provide detailed insight into the relative role of local tectonic activity of the thrust wedge and regional relative sea level fluctuations in the creation of unconformity bound depositional sequences. The tectonostratigraphic significances of the sequence boundaries of the Early-Late Miocene and Late Pliocene-middle Pleistocene sequences are remarkably similar. They reflect a “composite tectonic event” comprising an uplift/regression pulse, followed by a rapid subsidence/onlap. Each composite tectonic event, in turn, represents one pulse in the progressive evolution of the accretionary wedge system. We regard the middle Messinian-Early Pliocene phases of basin fill and tectonic inversion, and the Late Pleistocene-Recent uplift phase as reflections of the increase of regional stress in the Central Mediterranean.

    Description: The genus Ctenochaetus is reportad in the waters of the Colombian Pacific based on two specimens of C. marginatus (Valenciennes) collected in 1993 at Gorgona Island (2°59' N, 78° 12' W). These specimens differ inseveral morphometric characteristics from thosepreviously examined. Such differences appear to be an artifact of the small number of specimens formerly examined and the consequent narrow ranges reportad. We suggest that temperature variability affects the distribution of C. marginatus in the tropical eastern Pacific.

Estos ejemplares difieren inseveral características morfométricas de thosepreviously examinados. Estas diferencias parecen ser un artefacto del pequeño número de muestras examinadas anteriormente y reportad los rangos estrechos consecuente. Sugerimos que la variabilidad de la temperatura afecta la distribución de marginatus C en el Pacífico tropical oriental.

    Description: Over the last decade eutrophication of freshwater artificial reservoirs in Cuba occurred in parallel to oligotrophication of estuarine and coastal waters. These two processes influenced both freshwater and marine fisheries. A dramatic shift in species composition in freshwater fisheries has occurred, from dominance by cichlids (tilapia) to dominance by cyprinids. The high fishery yield from some reservoirs, and shift in species composition, seems related to progressive eutrophication of reservoirs by nutrient subsidies from different anthropogenic activities; particular those related to the size of urban areas within their watersheds. On the other hand, marine landings of estuarine-dependent species declined more significantly than for other groups associated with seagrass beds–coral reefs and oceanic waters. The ratio between catches of estuarine-dependent species and those associated with seagrass beds and coral reefs, decreased significantly over the last 20 years. The decrease in landings was more evident in typical estuarine species, such as shrimps (Litopenaeus schmitti and Farfantopenaeus notialis), mangrove oyster (Crassostrea rhizophorae) and mullets (Mugil spp.). River damming increased during the same period and is significantly correlated with these decreases. It is hypothesized that two different processes acted synergistically, leading to dramatic decreases of several orders of magnitude, in the catches of estuarine species over the last decade: the trapping of nutrients and sediments by river damming, and a drastic reduction in nutrient inputs from land-based sources due to reduced fertilizer use. These are postulated to have affected not only estuarine resources, but also the whole coastal ecosystem.
    Description: Durante la última década, la eutrofización de los embalses artificiales de agua dulce en Cuba se produjo en paralelo a oligotrophication de estuarios y costeras aguas. Estos dos procesos de influencia de agua dulce y la pesca marina. Un cambio dramático en la composición de las especies en la pesca de agua dulce se ha producido, de la dominación de los cíclidos (tilapia) a la dominación de ciprínidos. La alta producción de la pesca de algunos embalses, y el cambio en las especies composición, parece relacionada con la progresiva eutrofización de los embalses de las subvenciones de nutrientes de diferentes actividades antropogénicas, especialmente las relacionado con el tamaño de las zonas urbanas dentro de sus cuencas. Por otro lado, los desembarques de especies marinas de estuario-dependientes disminuyeron significativamente más que para otros grupos asociados con algas marinas Los arrecifes de coral-camas y las aguas oceánicas. La relación entre las capturas de las especies que dependen de los estuarios y las asociadas a las praderas marinas y Los arrecifes de coral, se redujo significativamente en los últimos 20 años. La disminución en los desembarques fue más evidente en especies típicas de estuarios, tales como camarones (Litopenaeus schmitti y Farfantopenaeus notialis), ostra de mangle (Crassostrea rhizophorae) y la lisa (Mugil spp.). El represamiento del Río aumentó durante el mismo período y se correlaciona significativamente con estas disminuciones. Se planteó la hipótesis de que dos procesos diferentes actúan de forma sinérgica, que conduce a una disminución drástica de varios órdenes de magnitud, en las capturas de las especies de estuario en la última década: la captura de nutrientes y sedimentos por represas río, y una reducción drástica de los aportes de nutrientes de fuentes terrestres, debido a la reducción del uso de fertilizantes. Se postula que han afectado no sólo a los recursos estuarinos, sino también todo el ecosistema costero.

    Description: Production of mangrove oyster (Crassostrea rhizophorae Guilding, 1828), north of Villa Clara, Cuba Province, tends to decline since 1980, accentuating from 2003 on. Despite regulations to protect the resource, minimum legal size and catch closures, the year 2008 presents the landing smaller volumes of the past 50 years. An analysis of the variability of catches in relation to natural and human factors, allows for precipitating causes of low productivity of this fishery resource; between the most representatives are expanding storage capacity of river water, salinity increment, the increase in frequency and intensity of hurricanes and the mismanagement of the extraction of oyster.
    Description: La producción de ostión de mangle (Crassostrea rhizophorae, Guilding, 1828), al norte de la provincia de Villa Clara, Cuba, tiende a la disminución desde de 1980, acentuándose a partir del año 2003. A pesar de regulaciones para la protección del recurso, talla mínima legal y vedas de captura, el año 2008 presenta los menores volúmenes de desembarque de los últimos 50 años. Un análisis de la variabilidad de las capturas, en relación con factores naturales y antrópicos, permite establecer causas desencadenantes de la baja productividad de este recurso pesquero; las más representativas son, la ampliación en la capacidad de embalse de aguas fluviales, aumentos de la salinidad, el incremento en la frecuencia e intensidad de los huracanes y un manejo inadecuado de la actividad extractiva de ostión.
