Opis:
New particle formation and growth were observed at a coastal site (Preila station, Lithuania) during 1997 and 2000–2002. The total amount of data analysed covers 291 one-day periods, 45 (15%) of which were long-term, new particle formation days. Short-term nucleation events (from a few minutes to one hour) and long-term events (from one to eight hours) were identified. The mean particle growth rate, condensation sink and condensable vapour source rate during nucleation events were 3.9 nm h−1, 1.45 × 10−3 cm−3 s−1 and 7.5 × 104 cm−3 s−1 respectively. The average formation rate J10 was 0.4 cm−3 s−1. The nucleation events were accompanied mainly by air masses transported from the north (43%) and north-west (19%). Meteorological parameters and trace gas (O3, SO2, NO2) concentrations were also analysed. It was found that nucleation events are related to high levels of solar radiation.

Opis:
Within the framework of the MEDCORE project on the ecology and management of Mediterranean coastal areas we decided to include the local dissemination of scientific results in Tunisia. The involvement of a local public school, and the joint work of local teachers and of local and international researchers, was chosen as a dissemination method because of the role of the school as an educational centre and the natural interest and curiosity characterising the schoolchildren. As the subject of the experience of dissemination a beach-dune system was considered suitable because of it was near, familiar and easy to reach, and also because of the economic importance of such environments, which generate considerable income as a result of tourists frequenting them. In environmental education, however, less emphasis is placed on this particular environment. A test performed before and after a school trip to the beach showed an increase in knowledge among children about beach-dune systems. Correlations between the gender and background of the children with their previous knowledge and information acquired from the field experience were analysed, and found to be not significant. All the children were equally receptive to environmental issues, regardless of their gender or background (urban/rural environment). One of the main results obtained through this experience is the effectiveness of sharing knowledge with local people, as stakeholders of study sites. The next step in the process of disseminating scientific knowledge for the benefit of the local community should be to examine its possible long-term effects.

Opis:
Coastal storms as extreme hydrometeorological events have severe impacts on the coasts and consequently affect the coastal communities, attracting considerable research interest nowadays. Attempting to understand the risk of these extreme events, a coastal storm analysis is accomplished by studying the parameters which define a coastal storm and their properties, such as the wave height, the wave period, the duration, the calm period, and the storm energy. The frequency of occurrence of coastal storms, the thresholds of storm parameters and the way they are interrelating with each other draw a rough outline of wave climate during coastal storm events for a specific location. This information is valuable afterwards for the design of coastal structures and the coastal zone management. In this work, buoy datasets from 30 locations in the Mediterranean Sea are analysed for describing coastal storm activity. A sample of 4008 coastal storms is identified. Each location faces around 10—14 coastal storms per year, with most of them to occur in winter months and their characteristics to be sitedependent. Their average duration is lower than 30 hours, and 25% of them are consecutive events which hit the same location in less than a day. Furthermore, the wave period and the main direction present no remarkable fluctuations during a coastal storm. With this analysis, a deeper understanding of coastal storm severity is pursued, gaining knowledge about their past activity, in order to be prepared in the future and to protect the coastal areas.

Opis:
Trophic models of the micro and meiobenthic community of six sandy beaches on the Ligurian coast (north-western Mediterranean Sea) have been performed to assess variations in structure and function of the ecosystem. A novel approach based on the determination of the feeding predisposition of the benthic community revealed that there is a significant shift in the trophodynamics of the system with respect to environmental constraints. Along an emerged-submerged gradient the benthic community displayed a clear trend from a fundamentally detritusdependent structure to an autotrophic, more balanced and diversified one. The trends analysed focus on the importance of the swash zone as a transitional area between the land and the sea that is characterised by a high diversity and activity of the trophic network.
